Setting device orientation in Swift iOS

Question

I am working on a swift app for iPhone  There is a modal view in my application that I want only to be in portrait view   My question is  how do I programmatically force the phone to not allow rotation  In other words  I am looking for code that will not allow a modal view to be displayed in landscape mode  turning on portrait rotation lock    This is just for 1 modal view  so I can t turn off rotation for the entire app  otherwise I would just disable rotation altogether   I found code in my research here But it is in objective C  in case that helps  Thanks

Hi for LandscapeLeft and LandscapeRight (Update Swift 2.0)

enter image description here And you have this in info

enter image description here

And UIController

override func shouldAutorotate() -> Bool {
    return true
}

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
    return [UIInterfaceOrientationMask.LandscapeLeft,UIInterfaceOrientationMask.LandscapeRight]
}

For PortraitUpsideDown and Portrait use that enter image description here

override func shouldAutorotate() -> Bool {
    if (UIDevice.currentDevice().orientation == UIDeviceOrientation.LandscapeLeft ||
        UIDevice.currentDevice().orientation == UIDeviceOrientation.LandscapeRight ||
        UIDevice.currentDevice().orientation == UIDeviceOrientation.Unknown) {
            return false
    }
    else {
        return true
    }
}

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
    return [UIInterfaceOrientationMask.Portrait ,UIInterfaceOrientationMask.PortraitUpsideDown]
}

Message from France, Merry Christmas !

Edit :

Other solution :

extension UINavigationController {
    public override func shouldAutorotate() -> Bool {
        if visibleViewController is MyViewController {
            return true   // rotation
        } else {
            return false  // no rotation
        }
    }

    public override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
        return (visibleViewController?.supportedInterfaceOrientations())!
    }
}

If someone wants the answer  I think I just got it  Try this    Go to your  plist file and check all the orientations  In the view controller you want to force orientation  add the following code    override func supportedInterfaceOrientations   - gt  UIInterfaceOrientationMask       return UIInterfaceOrientationMask Portrait toRaw   hashValue   UIInterfaceOrientationMask PortraitUpsideDown toRaw   hashValue     Hope it helps    EDIT    To force rotation  use the following code    let value   UIInterfaceOrientation LandscapeRight rawValue UIDevice currentDevice   setValue value  forKey   orientation     It works for iOS 7  amp  8

I ve been struggling all morning to get ONLY landscape left right supported properly  I discovered something really annoying  although the  General  tab allows you to deselect  Portrait  for device orientation  you have to edit the plist itself to disable Portrait and PortraitUpsideDown INTERFACE orientations - it s the last key in the plist   Supported Interface Orientations    The other thing is that it seems you must use the  mask  versions of the enums  e g   UIInterfaceOrientationMask LandscapeLeft   not just the orientation one  The code that got it working for me  in my main viewController    override func shouldAutorotate   - gt  Bool       return true    override func supportedInterfaceOrientations   - gt  Int       return Int UIInterfaceOrientationMask LandscapeLeft rawValue    Int UIInterfaceOrientationMask LandscapeRight rawValue      Making this combination of plist changes and code is the only way I ve been able to get it working properly

Go to your pList and add or remove the following as per your requirement    Supported Interface Orientations  - Array  Portrait  bottom home button   - String  Portrait  top home button   - String  Supported Interface Orientations  iPad   - Array  Portrait  bottom home button   - String  Portrait  top home button   - String  Landscape  left home button   - String  Landscape  right home button   - String   Note  This method allows rotation for a entire app    OR  Make a ParentViewController for UIViewControllers in a project   Inheritance Method        UIappViewController swift  import UIKit  class UIappViewController  UIViewController             super viewDidLoad              Making methods to lock Device orientation      override func supportedInterfaceOrientations   - gt  UIInterfaceOrientationMask           return UIInterfaceOrientationMask Portrait           override func shouldAutorotate   - gt  Bool           return false                                                                                                                                                  override func didReceiveMemoryWarning                 super didReceiveMemoryWarning                  Dispose of any resources that can be recreated                    Associate every view controller s parent controller as UIappViewController       LoginViewController swift  import UIKit import Foundation  class LoginViewController  UIappViewController       override func viewDidLoad                 super viewDidLoad              override func didReceiveMemoryWarning             super didReceiveMemoryWarning

Two suggestions with  Vivek Parihar s solution     If we are presenting any viewController we should check nil for    visibleViewController    in navigationController extension     extension UINavigationController   public override func shouldAutorotate   - gt  Bool       var shouldAutorotate   false     if visibleViewController    nil           shouldAutorotate   visibleViewController shouldAutorotate             return shouldAutorotate    public override func supportedInterfaceOrientations   - gt  Int       return visibleViewController supportedInterfaceOrientations        If We are using any action sheet to present and user will rotate upsideDown  Your action sheet will open from top edge of the screen  P  to solve this  we should take Portrait only  override func shouldAutorotate   - gt  Bool   if  UIDevice currentDevice   orientation    UIDeviceOrientation Portrait        UIDevice currentDevice   orientation    UIDeviceOrientation Unknown            return true   else       return false        override func supportedInterfaceOrientations   - gt  Int       return Int UIInterfaceOrientationMask Portrait rawValue

Swift 3  Orientation rotation is more complicated if a view controller is embedded in UINavigationController or UITabBarController the navigation or tab bar controller takes precedence and makes the decisions on autorotation and supported orientations   Use the following extensions on UINavigationController and UITabBarController so that view controllers that are embedded in one of these controllers get to make the decisions   UINavigationController extension  extension UINavigationController    override open var shouldAutorotate  Bool       get           if let visibleVC   visibleViewController               return visibleVC shouldAutorotate                   return super shouldAutorotate          override open var preferredInterfaceOrientationForPresentation  UIInterfaceOrientation      get           if let visibleVC   visibleViewController               return visibleVC preferredInterfaceOrientationForPresentation                   return super preferredInterfaceOrientationForPresentation          override open var supportedInterfaceOrientations  UIInterfaceOrientationMask      get           if let visibleVC   visibleViewController               return visibleVC supportedInterfaceOrientations                   return super supportedInterfaceOrientations             UITabBarController extension  extension UITabBarController    override open var shouldAutorotate  Bool       get           if let selectedVC   selectedViewController              return selectedVC shouldAutorotate                   return super shouldAutorotate          override open var preferredInterfaceOrientationForPresentation  UIInterfaceOrientation      get           if let selectedVC   selectedViewController              return selectedVC preferredInterfaceOrientationForPresentation                   return super preferredInterfaceOrientationForPresentation          override open var supportedInterfaceOrientations  UIInterfaceOrientationMask      get           if let selectedVC   selectedViewController              return selectedVC supportedInterfaceOrientations                   return super supportedInterfaceOrientations            Now you can override the supportedInterfaceOrientations  shouldAutoRotate and preferredInterfaceOrientationForPresentation in the view controller you want to lock down otherwise you can leave out the overrides in other view controllers that you want to inherit the default orientation behavior specified in your app s plist   Lock to Specific Orientation  class YourViewController  UIViewController   open override var supportedInterfaceOrientations  UIInterfaceOrientationMask      get           return  portrait            Disable Rotation      class YourViewController  UIViewController   open override var shouldAutorotate  Bool       get           return false            Change Preferred Interface Orientation For Presentation  class YourViewController  UIViewController   open override var preferredInterfaceOrientationForPresentation  UIInterfaceOrientation      get           return  portrait

From ios 10 0 we need    set   self orientations   newValue   for setting up the orientation  Make sure landscape property is enabled in your project   private var orientations   UIInterfaceOrientationMask landscapeLeft override var supportedInterfaceOrientations   UIInterfaceOrientationMask       get   return self orientations       set   self orientations   newValue

Swift 4   The simplest answer  in my case needing to ensure one onboarding tutorial view was portrait-only   extension myViewController         manage rotation for this viewcontroller     override open var supportedInterfaceOrientations  UIInterfaceOrientationMask           return  portrait           Eezy-peezy

User · Answer

This will disable autorotation of the view   override func shouldAutorotate   - gt  Bool       return false      Update  override func shouldAutorotate   - gt  Bool       if  UIDevice currentDevice   orientation    UIDeviceOrientation LandscapeLeft            UIDevice currentDevice   orientation    UIDeviceOrientation LandscapeRight            UIDevice currentDevice   orientation    UIDeviceOrientation Unknown                return false            else           return true            If app is in landscape mode and you show a view which must be showed in portrait mode  this will allow app to change it s orientation to portrait  of course when device will be rotated to such orientation

Above code might not be working due to possibility if your view controller belongs to a navigation controller  If yes then it has to obey the rules of the navigation controller even if it has different orientation rules itself  A better approach would be to let the view controller decide for itself and the navigation controller will use the decision of the top most view controller       We can support both locking to current orientation and autorotating to lock on a specific orientation with this generic extension on UINavigationController  -    extension UINavigationController               public override func shouldAutorotate   - gt  Bool                   return visibleViewController shouldAutorotate                          public override func supportedInterfaceOrientations   - gt  UIInterfaceOrientationMask               return  visibleViewController  supportedInterfaceOrientations                       Now inside your view controller we can   class ViewController  UIViewController          MARK  Autoroate configuration      override func shouldAutorotate   - gt  Bool           if  UIDevice currentDevice   orientation    UIDeviceOrientation Portrait                UIDevice currentDevice   orientation    UIDeviceOrientation PortraitUpsideDown                UIDevice currentDevice   orientation    UIDeviceOrientation Unknown                    return true                   else               return false                      override func supportedInterfaceOrientations   - gt  Int           return Int UIInterfaceOrientationMask Portrait rawValue    Int UIInterfaceOrientationMask PortraitUpsideDown rawValue            Hope it helps  Thanks
