There is a black bottom space under the camera

I represent UIImagePickerController

from UITabBarController

.

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

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

I explicitly set it showsCameraControls

to false to put my custom top view on top of the camera. But why is there black space at the bottom? Any help?

The aspect ratio of the camera is 4: 3, you need to apply the transformation scale so that you can get the 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);

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);
