There is a black bottom space below the camera

Question

I am presenting an UIImagePickerController from a UITabBarController.

        let imagePicker = UIImagePickerController()
        imagePicker.delegate = self
        imagePicker.sourceType = .Camera
        imagePicker.allowsEditing = false
        imagePicker.showsCameraControls = false

        presentViewController(imagePicker, animated: true, completion: nil)

I have explicitly set showsCameraControls to false to put my custom overlay view on top of camera.But why there is a black space on the bottom?any helps?

The camera aspect ratio is 4:3,you have to apply a transform scale so that you can get full screen

Swift

let screenSize = UIScreen.mainScreen().bounds.size
let aspectRatio:CGFloat = 4.0/3.0
let scale = screenSize.height/screenSize.width * aspectRatio
self.imagePikerViewController.cameraViewTransform = CGAffineTransformMakeScale(scale, scale);

Screen shot

Objective C

CGSize screenSize = [[UIScreen mainScreen] bounds].size;
float aspectRatio = 4.0/3.0;
float scale = screenSize.height/screenSize.width * aspectRatio;
self.imagePikerViewController.cameraViewTransform = CGAffineTransformMakeScale(scale, scale);

Does this still work with iOS 10? I tried this code and it doesn't work anymore. – ioskaveen Oct 11 '16 at 21:26

Not working for iOS 10. any other solution for this? – Vinod Singh Jun 16 '17 at 11:45
@Leo This works to remove the bottom black bar but it makes the camera zoomed in. The actual image captured in different (very zoomed out) from what is looked like while capturing the image. – Khadija Daruwala May 27 '21 at 13:19
