UIImagePickerController.frame is not full screen

Question

Hi!

I'm initializing an UIImagePickerController like this:

    self.cameraController = [[UIImagePickerController alloc] init];

    self.cameraController.sourceType = UIImagePickerControllerSourceTypeCamera; 
    self.cameraController.showsCameraControls = NO;
    self.cameraController.navigationBarHidden = YES;
    self.cameraController.wantsFullScreenLayout = YES;

The problem is that when this is shown, instead of the camera controls, I get a black bar in its place.

How can I make UIImagePickerController.frame take all the screen space?

Thanks!

The iPhone's camera has a 4:3 aspect ratio whereas the iPhone's screen's aspect ratio is 3:2. Therefore, the live camera picture does not cover the entire screen. If you want to get rid of the black bars, you have to apply a small scaling transform (e.g. 110%) to the camera view.
