Imagepicker overlay not display in fullscreen only in ios 10

I am using Imagepicker overlay to capture photos. In iOS 9 my code works fine, but when I run my code on iOS 10 it shows a space at the bottom which is not displayed on iOS 9 . I tried to solve it but I am not able to do it.

Here is my code that generates the issue:

- (void)openCamerawithOption :(UIImagePickerControllerCameraCaptureMode)camType
{
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{

[[NSOperationQueue mainQueue] addOperation:[NSBlockOperation blockOperationWithBlock:^{
[self createImagePicker:camType];
}]];
}
}

-(void)createImagePicker :(UIImagePickerControllerCameraCaptureMode)camType
{
if (!imagePickerController) {
imagePickerController = [[NonRotatableImagePickerController alloc] init];
}
//[imagePickerController.view setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height+(iOS7?0:20.0))];
[APPSINGLETON setBorder:imagePickerController.view color:[UIColor redColor]];

imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
imagePickerController.delegate = self;
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.allowsEditing = YES;
imagePickerController.videoMaximumDuration = 60.0;

if (iOS7) {
CGSize screenBounds = APPDELEGATE.screenSize;
CGFloat cameraAspectRatio = 4.0f/3.0f;
CGFloat camViewHeight = screenBounds.width * cameraAspectRatio;
CGFloat scale = screenBounds.height / camViewHeight;
imagePickerController.cameraViewTransform = CGAffineTransformMakeTranslation(0, (screenBounds.height - camViewHeight) / 2.0);
imagePickerController.cameraViewTransform = CGAffineTransformScale(imagePickerController.cameraViewTransform, scale, scale);
} else {
float cameraAspectRatio = 4.0 / 3.0;
float imageWidth = floorf(APPDELEGATE.screenSize.width * cameraAspectRatio);
float scale = ceilf(((APPDELEGATE.screenSize.height+20.0) / imageWidth) * 10.0) / 10.0;
imagePickerController.cameraViewTransform = CGAffineTransformMakeScale(scale, scale);
}

imagePickerController.mediaTypes = [NSArray arrayWithObjects:(NSString )kUTTypeMovie, (NSString )kUTTypeImage, nil];
imagePickerController.cameraCaptureMode = camType;
imagePickerController.showsCameraControls = NO;
imagePickerController.toolbar.hidden=YES;
imagePickerController.wantsFullScreenLayout = YES;

// not all devices have two cameras or a flash so just check here
if ([UIImagePickerController isCameraDeviceAvailable: UIImagePickerControllerCameraDeviceRear])
{
imagePickerController.cameraDevice = UIImagePickerControllerCameraDeviceRear;
}
else
{
imagePickerController.cameraDevice = UIImagePickerControllerCameraDeviceFront;
}

if ([UIImagePickerController isFlashAvailableForCameraDevice:imagePickerController.cameraDevice])
{
imagePickerController.cameraFlashMode = UIImagePickerControllerCameraFlashModeAuto;
}

[self performSelectorOnMainThread:@selector(presentPicker) withObject:nil waitUntilDone:YES];
}

-(void)presentPicker
{
[self presentViewController:imagePickerController animated:YES completion:nil];
imagePickerController.cameraOverlayView = transparentView;
}


Here is the screenshot

Update:

self.presentViewController(
self.imagePicker,
animated: true,
completion: {
let screenSize = UIScreen.mainScreen().bounds.size
let ratio: CGFloat = 4.0 / 3.0
let cameraHeight: CGFloat = screenSize.width * ratio
let scale: CGFloat = screenSize.height / cameraHeight

self.imagePicker.cameraViewTransform = CGAffineTransformMakeTranslation(0, (screenSize.height - cameraHeight) / 2.0)
self.imagePicker.cameraViewTransform = CGAffineTransformScale(self.imagePicker.cameraViewTransform, scale, scale)
}
)

This solution from below is working for me except when I rotate the device the same issue returns.


UIImagePickerController's cameraViewTransform is ignoring 'scaling' and 'translation' on iOS 10 beta

Answer

@chirag shah I did not found great solution for imagePicker transform in ios10. I just omitted imagepicker from my ios 10 project and use AVCaptureSession with video gravity AVLayerVideoGravityResizeAspectFill for AVCaptureVideoPreviewLayer object. It's work perfectly.
