[ios] How to change Status Bar text color in iOS

My application has a dark background, but in iOS 7 the status bar became transparent. So I can't see anything there, only the green battery indicator in the corner. How can I change the status bar text color to white like it is on the home screen?

Here is Apple Guidelines/Instruction about status bar change. Only Dark & light (while & black) are allowed in status bar.

Here is - How to change status bar style:

If you want to set status bar style, application level then set UIViewControllerBasedStatusBarAppearance to NO in your `.plist' file.

if you wan to set status bar style, at view controller level then follow these steps:

1. Set the UIViewControllerBasedStatusBarAppearance to YES in the .plist file, if you need to set status bar style at UIViewController level only.

2. In the viewDidLoad add function - setNeedsStatusBarAppearanceUpdate

3. override preferredStatusBarStyle in your view controller.

-

override func viewDidLoad() {
    super.viewDidLoad()
    self.setNeedsStatusBarAppearanceUpdate()
}

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

Set value of .plist according to status bar style setup level.

Here is some hacky trick to change/set background color for status bar during application launch or during viewDidLoad of your view controller.

extension UIApplication {

    var statusBarView: UIView? {
        return value(forKey: "statusBar") as? UIView
    }

}

// Set upon application launch, if you've application based status bar
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        UIApplication.shared.statusBarView?.backgroundColor = UIColor.red
        return true
    }
}


or 
// Set it from your view controller if you've view controller based statusbar
class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        UIApplication.shared.statusBarView?.backgroundColor = UIColor.red
    }

}

Here is result:

• Delete the View controller-based status bar appearance in .plist file (if u have create) and recreate it.

• set Status Bar style to Opaque black style

In appDelegate add the following code under didFinishLaunching.

 [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

Just two steps as following:

Step 1:

Under the Info tab of the project target, Add Row:

UIViewControllerBasedStatusBarAppearance, set value NO.

Step 2:

In the project AppDelegate.m:

- (BOOL)application:(UIApplication *)application 
        didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
    …
    [application setStatusBarStyle:UIStatusBarStyleLightContent];
    …
}

In Info.plist set 'View controller-based status bar appearance' as NO

In AppDelegate add

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

In case your UIViewController is inside a UINavigationController you will have to set the BarStyle:

-[UINavigationBar setBarStyle:UIBarStyleBlack]

Original Answer is here

In iOS 8: add NavigationController.NavigationBar.BarStyle = UIBarStyle.Black; to viewDidLoad

The key to making this work is that only the fullscreen view controller get's to dictate the style of the status bar.

If you are using a navigation controller and want to control the status bar on a per view controller basis, you'll want to subclass UINavigationController and implement preferredStatusBarStyle such that it returns the topViewController's preference.

Make sure you change the class reference in your storyboard scene fromUINavigationController to your subclass (e.g. MyNavigationController in the example below).

(The following works for me. If your app is TabBar based, you'll want to do something similar by subclassing the UITabBarController but I haven't tried that out).

@interface MyNavigationController : UINavigationController

@end

@implementation MyNavigationController

- (UIStatusBarStyle)preferredStatusBarStyle
{
    return self.topViewController.preferredStatusBarStyle;
}

@end

1. Go to Project -> Target,

2. Then set Status Bar Style to Light. It makes status-bar white from the launch screen.

3. Then set View controller-based status bar appearance equal to NO in Info.plist.

Let me give you a complete answer to your question. Changing the status bar text color is very easy but its a little confusing in iOS 7 specially for newbies.

If you are trying to change the color from black to white in Storyboard by selecting the view controller and going to Simulated Metrics on the right side, it won't work and i don't know why. It should work by changing like this but any how.

Secondly, you won't find UIViewControllerBasedStatusBarAppearance property in your plist but by default its not there. You have to add it by yourself by clicking on the + button and then set it to NO.

ios 7 status bar text color

Lastly, you have to go to your AppDelegate.m file and add the following in didFinishLaunchingWithOptions method, add the following line:

     [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

This will change the color to white for all your view controllers. Hope this helps!

Just Change in 1) Info.plist View controller-based status bar appearance -> NO and write 2)

  [[UIApplication
 sharedApplication]setStatusBarStyle:UIStatusBarStyleLightContent]; 

in

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

In Swift 3 is very easy just with 2 steps. Go to your info.plist and change the key View controller-based status bar appearance to "NO". Then in the Appdelegate just add this line in didfinishlaunchingwithoptions method

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        UIApplication.shared.statusBarStyle = .lightContent
        return true
    }

this has been deprecated in iOS9 now you should do override this property in the rootviewcontroller

doing this has been deprecated in iOS 9 should do this on the rootviewcontroller

override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
 }

Just to summarize, edit your project Info.plist and add:

View controller-based status bar appearance : NO

Status bar style : Opaque black style

or if you have raw key/value plist

UIViewControllerBasedStatusBarAppearance : NO

UIStatusBarStyle : Opaque black style

For Xcode 5.1:

Add "View controller-based status bar appearance" to NO in the .plist.

In AppDelegate, add:

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

That's all!

The easiest way to do this from Xcode (without any coding) is:

• Add View controller-based status bar appearance to your Info.plist and set the value to NO.
• Now, go to your project target and inside Deployment Info you'll find an option for Status Bar Style. Set the value of this option to Light.

You'll have the White status bar.

You can use this for iOS 6 and 7:

#ifdef __IPHONE_7_0
# define STATUS_STYLE UIStatusBarStyleLightContent
#else
# define STATUS_STYLE UIStatusBarStyleBlackTranslucent
#endif

[[UIApplication sharedApplication] setStatusBarStyle:STATUS_STYLE animated:YES];

change the status bar text color for all ViewControllers

swift 3

if View controller-based status bar appearance = YES in Info.plist

then use this extension for all NavigationController

extension UINavigationController
{
    override open var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
     }
 }

if there is no UINavigationController and only have UIViewController then use Below code:

extension UIViewController
{
    override open var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
     }
 }

objective c

create category class

For UIViewController

In UIViewController+StatusBarStyle.h

 @interface UIViewController (StatusBarStyle)
 @end

In UIViewController+StatusBarStyle.m

 #import "UIViewController+StatusBarStyle.h"

 @implementation UIViewController (StatusBarStyle)
 -(UIStatusBarStyle)preferredStatusBarStyle
 {
  return UIStatusBarStyleLightContent;
 }
 @end 

For UINavigationController

In UINavigationController+StatusBarStyle.h

 @interface UINavigationController (StatusBarStyle)
 @end

In UINavigationController+StatusBarStyle.m

 #import "UINavigationController+StatusBarStyle.h"

 @implementation UINavigationController (StatusBarStyle)
 -(UIStatusBarStyle)preferredStatusBarStyle
 {
  return UIStatusBarStyleLightContent;
 }
 @end  

I did some things different and it works for me.

With no changes in code, I did config my .plist file like this:

• View controller-based status bar appearance > NO
• Status bar style > UIStatusBarStyleLightContent (simple string)

I hope it helps.

edit

For each view controller I change the "status bar"'s Simulated Metrics property, in storyboard, from "inferred" to "Light Content"

This worked for me:

1. Set the UIViewControllerBasedStatusBarAppearance to YES in the plist

2. The rootViewController needs the method implementation for

   -(UIStatusBarStyle)preferredStatusBarStyle
   

Because my rootViewController is managed by Cocoapods (JASidePanelController) I added this method through a category:

#import "JASidePanelController+StatusBarStyle.h"

@implementation JASidePanelController (StatusBarStyle)

- (UIStatusBarStyle)preferredStatusBarStyle
{
    return UIStatusBarStyleLightContent;
}

@end

Well, this is really working like a piece of cake for me.

Go to your app's info.plist.

1. Set View controller-based status bar appearance to NO
2. Set Status bar style to UIStatusBarStyleLightContent

Then go to your app's delegate and paste in the following code where you set your windows's RootViewController.

#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
    UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0,320, 20)];
    view.backgroundColor=[UIColor colorWithRed:0/255.0 green:0/255.0 blue:0/255.0 alpha:1.0];
    [self.window.rootViewController.view addSubview:view];
}

Bingo. It's working for me.

None of that worked for me, so here is a working solution...

In Info.plist, add a row:

UIViewControllerBasedStatusBarAppearance, and set the value NO.

Then in AppDelegate in didFinishLaunchingWithOptions, add these rows:

[application setStatusBarHidden:NO];
[application setStatusBarStyle:UIStatusBarStyleLightContent];

Simply In Appdelegate

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

If your application needs to have UIStatusBarStyleLightContent by default, but you still want to have the ability to use UIStatusBarStyleDefault on some screens, you could choose to manage the status bar color on the controller level, but in this case you'll have to overwrite preferredStatusBarStyle in every view controller (or implement it in a base view controller, from which all your other view controllers will inherit). Here's another way of solving this problem:

• Set the UIViewControllerBasedStatusBarAppearance to NO in the plist
• Set the UIStatusBarStyle to UIStatusBarStyleLightContent

All view controllers will use white text for the status bar. Now add this methods only in the view controllers that need the status bar with black text:

-(void)viewWillAppear:(BOOL)animated  
{  
  [super viewWillAppear:animated];  
  [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
}    

-(void)viewWillDisappear:(BOOL)animated  
{  
  [super viewWillAppear:animated];  
  [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}    

in info.plist set the field value NO View controller-based status bar appearance and set statusbar style light in target > general setting.

If you still want to use View controller-based status bar appearance in info.plist set to YES, meaning that you can change the statusbar for each view-controller, use the following for white text in the status-bar in ViewDidLoad:

[[[self navigationController] navigationBar] setBarStyle:UIBarStyleBlackTranslucent];

This is documented in the iOS 7 UI Transition Guide, which you need an Apple developer ID to access directly. The relevant excerpt:

Because the status bar is transparent, the view behind it shows through. [...] Use a UIStatusBarStyle constant to specify whether the statusbar content should be dark or light:

UIStatusBarStyleDefault displays dark content. [...]

UIStatusBarStyleLightContent displays light content. Use when dark content is behind the status bar.

Also possibly of interest:

In iOS 7, you can control the style of the status bar from an individual vew controller and change it while the app runs. To opt in to this behavior, add the UIViewControllerBasedStatusBarAppearance key to an app's Info.plist file and give it the value YES.

I'd definitely recommend having a look through the document, which, again, you can access with your Apple developer ID.

iOS 13 Solution(s)

UINavigationController is a subclass of UIViewController (who knew )!

Therefore, when presenting view controllers embedded in navigation controllers, you're not really presenting the embedded view controllers; you're presenting the navigation controllers! UINavigationController, as a subclass of UIViewController, inherits preferredStatusBarStyle and childForStatusBarStyle, which you can set as desired.

Any of the following methods should work:

1. Opt out of Dark Mode entirely
   • In your info.plist, add the following property:
     • Key - UIUserInterfaceStyle (aka. "User Interface Style")
     • Value - Light

2. Override preferredStatusBarStyle within UINavigationController

   • preferredStatusBarStyle (doc) - The preferred status bar style for the view controller

   • Subclass or extend UINavigationController

     class MyNavigationController: UINavigationController {
         override var preferredStatusBarStyle: UIStatusBarStyle {
             .lightContent
         }
     }
     

     OR

     extension UINavigationController {
         open override var preferredStatusBarStyle: UIStatusBarStyle {
             .lightContent
         }
     }
     

3. Override childForStatusBarStyle within UINavigationController

   • childForStatusBarStyle (doc) - Called when the system needs the view controller to use for determining status bar style
   • According to Apple's documentation,

     "If your container view controller derives its status bar style from one of its child view controllers, [override this property] and return that child view controller. If you return nil or do not override this method, the status bar style for self is used. If the return value from this method changes, call the setNeedsStatusBarAppearanceUpdate() method."

   • In other words, if you don't implement solution 3 here, the system will fall back to solution 2 above.

   • Subclass or extend UINavigationController

     class MyNavigationController: UINavigationController {
         override var childForStatusBarStyle: UIViewController? {
             topViewController
         }
     }
     

     OR

     extension UINavigationController {    
         open override var childForStatusBarStyle: UIViewController? {
             topViewController
         }
     }
     

   • You can return any view controller you'd like above. I recommend one of the following:

     • topViewController (of UINavigationController) (doc) - The view controller at the top of the navigation stack
     • visibleViewController (of UINavigationController) (doc) - The view controller associated with the currently visible view in the navigation interface (hint: this can include "a view controller that was presented modally on top of the navigation controller itself")

Note: If you decide to subclass UINavigationController, remember to apply that class to your nav controllers through the identity inspector in IB.

P.S. This works on iOS 13

I think all the answers do not really point the problem because all of them work in specific scenarios. But if you need to cover all the cases follow the points bellow:

Depending on where you need the status bar light style you should always have in mind these 3 points:

1)If you need the status bar at the launch screen or in other places, where you can't control it (not in view controllers, but rather some system controlled elements/moments like Launch Screen) You go to your project settings

2) if you have a controller inside a navigation controller You can change it in the interface builder as follows:

a) Select the navigation bar of your navigation controller

b) Then set the style of the navigation bar to "Black", because this means you'll have a "black" -> dark background under your status bar, so it will set the status bar to white

Or do it in code as follows

navigationController?.navigationBar.barStyle = UIBarStyle.Black

3) If you have the controller alone that needs to have it's own status bar style and it's not embedded in some container structure as a UINavigationController

Set the status bar style in code for the controller:

If you want to set it to any color, use below code.

id statusBarWindow = [[UIApplication sharedApplication] valueForKey:@"statusBarWindow"];
id statusBar = [statusBarWindow valueForKey:@"statusBar"];

SEL setForegroundColor_sel = NSSelectorFromString(@"setForegroundColor:");
if([statusBar respondsToSelector:setForegroundColor_sel]) {
    // iOS 7+
    [statusBar performSelector:setForegroundColor_sel withObject:YourColorHere];
                                                                 ^^^^^^^^^^^^^
}

I know I am accessing private API, but I have used this in many projects and Apple have approved it.

Just while submitting the app, send this code to Apple in Comments section and inform that you are using this code to change the status bar color.

And yes, don't forget below too.

I'm using Xcode 6 beta 5 on a Swift project, for an iOS 7 app.

Here is what I did, and it works:

info.plist:

Swift 3 - Xcode 8.

If you want status bar to initially hidden on Launch screen then try this,

Step 1: Add following to info.plist.

• View controller-based status bar appearance value NO
• Status bar is initially hidden value YES

Step 2: Write this in didFinishLaunchingWithOptions method.

UIApplication.shared.isStatusBarHidden = false
UIApplication.shared.statusBarStyle = UIStatusBarStyle.lightContent

iOS 7 allows individual view controllers to determine the appearance of the status bar, as described by the Apple developer documentation:

iOS 7 gives view controllers the ability to adjust the style of the status bar while the app is running. A good way to change the status bar style dynamically is to implement preferredStatusBarStyle and—within an animation block—update the status bar appearance and call setNeedsStatusBarAppearanceUpdate.

Setting the status bar appearance globally is a two-step process.

First, you need to tell iOS that you don't want to set the status bar appearance on a view-by-view basis.

Then you need to take charge and actually set the new global status bar style.

To disable view-by-view status bar control, you'll need to set the View controller-based status bar appearance property in Info.plist.

Open the Project Navigator and select the project for your iOS app, then select the Info tab.

Hover over a row, then click the plus sign that appears to add a new property to your .plist.

Enter View controller-based status bar appearance in the Key field, then make sure the Type field is set to Boolean. Finally, enter NO in the Value field.

To set a global style for the status bar, add another property under the Info tab with a key of Status bar style, a Type of String and a Value of Opaque black style.

Here's a blog post with a little more detail and some sample code:

http://codebleep.com/setting-the-status-bar-text-color-in-ios-7/

Very Easy way To change the status bar color. Create the subclass of navigation Controller.

Write this code in view didload method. Effect this code in all view controller

self.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName :
                                                                        [UIColor whiteColor],
                                               NSFontAttributeName:[UIFont boldSystemFontOfSize:19]};

In Plist, add this:

• Status bar style: UIStatusBarStyleLightContent
• View controller-based status bar appearance: NO

What I had to do for swift and navigation controller

extension UINavigationController {
    override open var preferredStatusBarStyle: UIStatusBarStyle {
       return .lightContent
    }   
}

You can do this from info.plist:

1) "View controller-based status bar appearance" set to "NO"

2) "Status bar style" set to "UIStatusBarStyleLightContent"

done

You dont need to do any code for this

You need to add "View controller-based status bar appearance" key in info.plist as follows:

& set its value type to Boolean & value to NO. Then click on project settings,then click on General Tab & under Deployment Info set the preferred status bar style to .Light as follows:

Thats it.

I make this in iOS 9 and Swift 2.0 if I use UINavigationController

self.navigationController?.navigationBar.barStyle = UIBarStyle.Black

And I make this if I use modal segue

override func preferredStatusBarStyle() -> UIStatusBarStyle {
    return .LightContent
}

For me, nothing happened with using all the things in the other answers (and from other sources/documentation). What did help was to set the Navigation Bar Style to "Black" in the XIB. This changed the text to white without any code at all.

Simply calling

[[UINavigationBar appearance] setBarStyle:UIBarStyleBlack];

in the

-(BOOL)application:(UIApplication *)application 
           didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
}

method of my AppDelegate works great for me in iOS7.

On iOS 7, if you want to use UIViewControllerBasedStatusBarAppearance == YES, and your root view controller is UINavigationController, you should subclass it and overload childViewControllerForStatusBarStyle, for example, like this:

- (UIViewController*) childViewControllerForStatusBarStyle
{
    return self.viewControllers.lastObject;
}

After this, preferredStatusBarStyle will be called on pushed view controllers.

If you want the same result with Swift, you can use this code in your AppDelegate.swift file :

UINavigationBar.appearance().barStyle = .BlackTranslucent

And the text of your status bar will be white :-) !

Please try this

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
    [application setStatusBarHidden:NO];
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
    UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"];
    if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) {
        statusBar.backgroundColor = [UIColor blackColor];
    }

If you have an embedded navigation controller created via Interface Builder, be sure to set the following in a class that manages your navigation controller:

-(UIStatusBarStyle)preferredStatusBarStyle{ 
    return UIStatusBarStyleLightContent; 
} 

That should be all you need.

Alternatively, you can opt out of the view-controller based status bar appearance:

1. Set View controller-based status bar appearance to NO in your Info.plist.
2. Call [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

Note: This method has been deprecated in iOS9. Use preferredStatusBarStyle on the UIViewController instead. (see Apple Developer Library)

No need do some extra , just write this code in your viewController and get status bar color white

- (UIStatusBarStyle)preferredStatusBarStyle{return UIStatusBarStyleLightContent;}

Answer updated for for Xcode GM Seed:

1. In Info.plist put View controller-based status bar appearance as NO

2. In the project, set:

   

3. In ViewDidLoad:

   [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

Here is a better solution extend Navigation controller and put in storyboard

class NVC: UINavigationController {

    override var preferredStatusBarStyle: UIStatusBarStyle {
              return .lightContent
    }

    override func viewDidLoad() {
        super.viewDidLoad()

    self.navigationBar.isHidden = true
    self.navigationController?.navigationBar.isTranslucent = false
      
     self.navigationBar.barTintColor = UIColor.white
     setStatusBarColor(view : self.view)
    }
    

    func setStatusBarColor(view : UIView){
             if #available(iOS 13.0, *) {
                 let app = UIApplication.shared
                 let statusBarHeight: CGFloat = app.statusBarFrame.size.height
                 
                 let statusbarView = UIView()
              statusbarView.backgroundColor = UIColor.black
                 view.addSubview(statusbarView)
               
                 statusbarView.translatesAutoresizingMaskIntoConstraints = false
                 statusbarView.heightAnchor
                     .constraint(equalToConstant: statusBarHeight).isActive = true
                 statusbarView.widthAnchor
                     .constraint(equalTo: view.widthAnchor, multiplier: 1.0).isActive = true
                 statusbarView.topAnchor
                     .constraint(equalTo: view.topAnchor).isActive = true
                 statusbarView.centerXAnchor
                     .constraint(equalTo: view.centerXAnchor).isActive = true
               
             } else {
                 let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
              statusBar?.backgroundColor = UIColor.black
             }
         }
}

status bar color will be black and text will be white

This works in Golden Master iOS 7 and Xcode 5 GM seed and iOS7 SDK released on September 18th, 2013 (at least with navigation controller hidden):

1. Set the UIViewControllerBasedStatusBarAppearance to NO in the Info.plist.

2. In ViewDidLoad method or anywhere, where do you want to change status bar style: [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

In AppDelegate.m, add the following.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

} 

And in the Plist file, set 'View controller-based status bar appearance' to NO.

This does seem to be an issue with the current build of Xcode and iOS 7.

Some related content on Apple's Developer Forums is in a search for UIStatusBarStyleLightContent in "iOS 7 Beta Livability" on the Apple Developer Forums* (currently 32 posts).

I came across it trying to set it to the light version.

(This is just a follow up on Aaron's answer.)

You can do this without writing any line of code!
Do the following to make the status bar text color white through the whole app

On you project plist file:

• Status bar style: Transparent black style (alpha of 0.5)
• View controller-based status bar appearance: NO
• Status bar is initially hidden: NO

extension UIApplication {

    var statusBarView: UIView? {
        return value(forKey: "statusBar") as? UIView
    }
}

In my case for Swift 5, I added these lines:

override func viewDidAppear(_ animated: Bool) {
    navigationController?.navigationBar.barStyle = .black
}

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

Note: Most upvoted answer does not work for iOS 7 / 8

In Info.plist set 'View controller-based status bar appearance' as NO

In AppDelegate add

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

to

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
   ......
   ...
}    

This solution works for iOS 7 / 8
