UIImagePickerController how to do animated switch from rear to front camera?

Question

I have been using custom overlay for UIImagePickerController controller, and everything is working fine. I have added button to switch between front and rear camera

Answer 1

I was trying to do this today, and I was able to get it working with the following code:

[UIView transitionWithView:imagePickerController.view duration:1.0 options:UIViewAnimationOptionAllowAnimatedContent | UIViewAnimationOptionTransitionFlipFromLeft animations:^{
            imagePickerController.cameraDevice = UIImagePickerControllerCameraDeviceRear;
        } completion:NULL];

I hope this helps anyone who comes across this question.

Answer 2

Here's the Swift code for the accepted answer in case someone needs it:

UIView.transitionWithView(imagePickerController.view!, duration: 1.0, options: [.AllowAnimatedContent, .TransitionFlipFromLeft], animations: {() -> Void in
            imagePickerController.cameraDevice = .Rear
            }, completion: nil)

Thanks Pablo!
