Change device orientation, swift, iOS,

Question

How I could change the device orientation to Portrait with code?

In order to open the camera and library in portrait from the view controller.

I would like to include in this button:

@IBAction func openCamera(sender: AnyObject) { ///accion del boton Camara

  // Create image picker controller let image = UIImagePickerController() image.delegate = self image.sourceType = UIImagePickerControllerSourceType.Camera image.cameraDevice = UIImagePickerControllerCameraDevice.Front self.presentViewController(image, animated: true, completion: nil) } 

I got this error:

Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and [PLUICameraViewController shouldAutorotate] is returning YES' *** First throw call stack: (0x18150ee38 0x180b73f80 0x18150ed80 0x1866d1af0 0x1866db150 0x1866db0c8 0x1866d9bb0 0x186653910 0x1866536ac 0x1866536ac 0x1866536ac 0x186652c40 0x181e40d50 0x186652ac4 0x186660578 0x18675a11c 0x186759a40 0x1869b8740 0x18690afd8 0x186918990 0x18664a4a4 0x1814c47b0 0x1814c2554 0x1814c2984 0x1813ecd10 0x182cd4088 0x1866c1f70 0x1000675ac 0x180f8a8b8) libc++abi.dylib: terminating with uncaught exception of type NSException (lldb)

When I use

> presentViewController(cameraViewController, animated: true,
> completion: nil)
>     }
>     */
>     
>         // Create image picker controller
>         
>         
>         let image = UIImagePickerController()
>         
>         image.delegate = self
>         
>         image.sourceType = UIImagePickerControllerSourceType.Camera
>         image.cameraDevice  = UIImagePickerControllerCameraDevice.Front
>         self.presentViewController(image, animated: true, completion: nil)
>     }

Answer 1

In order to change orientation programmatically, use this :

let value = UIInterfaceOrientation.Portrait.rawValue
UIDevice.currentDevice().setValue(value, forKey: "orientation")

Answer 2

forcing the device orientation is not the way to go. the problem is also not the device but the interface orientation :) there is a distinction to read about

but to solve the issue, just allow portrait mode in your app and that you specify in your AppDelegate or your app's plist. :)

//allow rotation for app
- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(nullable UIWindow *)window {
    return UIInterfaceOrientationMaskAll;
}

... you can THEN forbid it for certain VCs instead of for everything ...

//for a vc
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscapeLeft;
}
- (BOOL)shouldAutorotate {
    return YES;
}

Answer 3

Use setter method for setting up orientation

  private var orientations = UIInterfaceOrientationMask.landscapeLeft
    override var supportedInterfaceOrientations : UIInterfaceOrientationMask {
        get { return self.orientations }
        set { self.orientations = newValue }
    }
