Displaying splash screen for longer than default seconds

Question

Is it possible to display the Default png for a specified number of seconds  I have a client that wants the splash screen displayed for longer than its current time   They would like it displayed for 2 - 3 seconds

User · Answer

Use following line in didFinishLaunchingWithOptions  delegate method    NSThread sleepForTimeInterval 5 0     It will stop splash screen for 5 0 seconds

No  the default png is shown while your app starts up   You can add a new viewcontroller which will display the default png in the application didFinishLoading   This way you display the default png a bit longer   You should only show the default png if you are loading data  which could take some time  As the appstore guidelines state  you should not delay starting of you are any longer than necessary

If you are using the LaunchScreen storyboard you can obtain the same view controller and present it   remember to set the storyboard id  for example  LaunchScreen    func applicationDidBecomeActive application  UIApplication             let storyboard   UIStoryboard name   LaunchScreen   bundle  nil          let vc   storyboard instantiateViewControllerWithIdentifier  LaunchScreen   self window  rootViewController  presentViewController vc  animated  false  completion  nil              SWIFT 4  let storyboard   UIStoryboard name   LaunchScreen   bundle  nil  let vc   storyboard instantiateViewController withIdentifier   LaunchScreen    self window  rootViewController  present vc  animated  false  completion  nil

1 Add a another view controller in    didFinishLaunchingWithOptions      UIStoryboard  storyboard    UIStoryboard storyboardWithName   Main  bundle nil    UINavigationController  homeNav    storyboard instantiateViewControllerWithIdentifier   NavigationControllerView    UIViewController  viewController    storyboard instantiateViewControllerWithIdentifier   SplashViewController     self window     UIWindow alloc  initWithFrame   UIScreen mainScreen  bounds    self window rootViewController   homeNav   self window makeKeyAndVisible      UINavigationController   self window rootViewController pushViewController viewController animated NO       2 In view did load of SplashView Controller     self performSelector  selector removeSplashScreenAddViewController  withObject nil afterDelay 2 0     3 In removeSplashScreenAddViewController method you can add your main view controller for eg -  -  void  removeSplashScreenAddViewController     UIStoryboard  storyboard    UIStoryboard storyboardWithName   Main  bundle nil   UINavigationController  homeNav    storyboard instantiateViewControllerWithIdentifier   HomeNav    UIViewController  viewController    storyboard instantiateViewControllerWithIdentifier viewControllerName    UIWindow  window     StaticHelper mainWindow   window rootViewController   homeNav   window makeKeyAndVisible      UINavigationController   window rootViewController pushViewController viewController animated NO

This works     -  BOOL application  UIApplication   application didFinishLaunchingWithOptions  NSDictionary   launchOptions          Load Splash View Controller first     self window     UIWindow alloc  initWithFrame UIScreen mainScreen bounds       UIStoryboard  storyboard    UIStoryboard storyboardWithName   MainStoryboard  bundle nil       UIViewController  viewController    storyboard instantiateViewControllerWithIdentifier   Splash        self window rootViewController   viewController       self window makeKeyAndVisible           Load other stuff that requires time         Now load the main View Controller that you want

The simplest way to achieve this is to creat an UIImageView with  Default png  on the top of your first ViewController s UIView    And add an Timer to remove the UIImageView after seconds you expected

You can also use NSThread    NSThread sleepForTimeInterval  NSTimeInterval      You can put this code in to first line of applicationDidFinishLaunching method   For example  display default png for 5 seconds   -  void  applicationDidFinishLaunching  UIApplication  application       NSThread sleepForTimeInterval 5 0

You can simple specify number of seconds to sleep in the AppDelegate didFinishLaunchingWithOptions method   Or alternatively use another ImageView to customize the splash screen    See details for the latter at the following link by me   Splash Screen Problem

User · Answer

The simplest solution here is to add sleep   to didFinishLaunchingWithOptions method in your AppDelegate class    Swift 4   sleep 1     delays the LaunchScreen by 1 second    If you wanna do something fancier you can also extend the current RunLoop in the same method   Swift 4   RunLoop current run until  Date timeIntervalSinceNow  1

Put your default png in a UIImageView full screen as a subview on the top of your main view thus covering your other UI  Set a timer to remove it after x seconds  possibly with effects  now showing your application

User · Answer

You can create your own view and display it when application starts and hide it with timer  Please avoid delaying app start as its bad idea

Swift 3  This is doable in a safe way by presenting the splash controller for what ever time you specify then remove it and display your normal rootViewController    First in LaunchingScreen storyboard give your controller a StoryBoard identifier let s say  splashController  In Main storyboard give your initial viewController a StoryBoard identifier let s say  initController   -This could be nav or tab bar etc   -   In AppDelegate you can create these 2 methods    private func extendSplashScreenPresentation           Get a refernce to LaunchScreen storyboard     let launchStoryBoard   UIStoryboard init name   LaunchScreen   bundle  nil         Get the splash screen controller     let splashController   launchStoryBoard instantiateViewController withIdentifier   splashController          Assign it to rootViewController     self window  rootViewController   splashController     self window  makeKeyAndVisible          Setup a timer to remove it after n seconds     Timer scheduledTimer timeInterval  5  target  self  selector   selector dismissSplashController   userInfo  nil  repeats  false       2    objc private func dismissSplashController            Get a refernce to Main storyboard     let mainStoryBoard   UIStoryboard init name   Main   bundle  nil         Get initial viewController     let initController   mainStoryBoard instantiateViewController withIdentifier   initController          Assign it to rootViewController     self window  rootViewController   initController     self window  makeKeyAndVisible       Now you call    self extendSplashScreenPresentation     in didFinishLaunchingWithOptions   You are set to go
