Black view at bottom when using custom camera overlay view (UIImagePickerController)

Question

I want to use custom camera overlay view. Below is the code for it.

imagePicker = [[UIImagePickerController alloc] init];
self.imagePicker.delegate = self;
self.imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.imagePicker.showsCameraControls = NO;
self.imagePicker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
self.imagePicker.toolbarHidden = YES;
self.imagePicker.wantsFullScreenLayout = YES;
self.imagePicker.navigationBarHidden = YES;
self.imagePicker.cameraOverlayView = [self cameraOverlayView];

The issue is there is a black background at bottom and I don't get from where it is coming. What is wrong in code?

Is something in [self cameraOverlayView] ? method ? i have commented on that line, and its working fine with ios 6 . — Toseef Khilji, Nov 29 '13 at 10:09
I dont know whats wrong with you, i have run same code and its working. — Toseef Khilji, Nov 29 '13 at 10:12
@Virussmca OMG. It is not a toolbar but a black background but its not mine. It is at bottom and have same size as toolbar. It seems from default camera view. Have you ever seen it? — Geek, Nov 29 '13 at 10:13
Yes. that is not toolbar. check at least before posting question. — Toseef Khilji, Nov 29 '13 at 10:15

Try cameraViewTransform for full screen.

    CGFloat camScaleup = 2;
    imagePicker.cameraViewTransform = CGAffineTransformScale(imagePicker.cameraViewTransform, camScaleup, camScaleup);

It works but cannot understand it. Can you describe your logic of how and why you use aspect ratio to calculate scale? – Geek Nov 29 '13 at 10:44
Sorry Logic is not created by me, i have just refere you. – Toseef Khilji Nov 29 '13 at 10:47
It does not give correct scale value. Still there is a small black background. – Geek Nov 29 '13 at 10:54
The camera's image itself is not large enough and needs to be scaled to fit the space. – Toseef Khilji Nov 29 '13 at 10:58
@Akash: check updated answer, that is the maximum camera screen you can show with uiimagePicker. – Toseef Khilji Nov 29 '13 at 11:01
Why 2? You could have taken 4.0/3.0 i.e. 1.33. – Geek Nov 29 '13 at 11:04
its direct value , removing calculation. – Toseef Khilji Nov 29 '13 at 11:08
Sorry but this does not fix the issue. This property is to change the zoom of the camera and not to scale up the live view of the camera – Camus Feb 17 '14 at 23:04
