iOS 4.3 changed transformation on UIImagePickerController's camera overlay view

After testing my App on iOS 4.3 I noticed that the camera overlay of my UIImagePickerController has an added transfor开发者_JS百科mation that stretched the content extremely. Pre iOS 4.3 everything shows up correctly.

Here is what I do

imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;

cameraOverlay = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
cameraOverlay.backgroundColor = [UIColor clearColor];
cameraOverlay.userInteractionEnabled = NO;

//add subviews to camera Overlay

imagePicker.cameraOverlayView = pauseButton;

Any ideas what I have to do to get rid of the added transformation?

OK found the answer. ios 4.3 requires to have the camerOverlay as big as the screen is. So my 200x200 camera overlay was enlarged.

If I change the line:

cameraOverlay = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];

to

cameraOverlay = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];

it works :).
