UIImagePickerController Orientation

Question

I am creating an UIImagePickerController for a full screen camera using a custom OverLayView but when ever I rotate my device I get an error saying "CGAffineTransformInvert: singular matrix." As a reference to how I am going about doing this I am following this tutorial: http://blog.blackwhale.at/?p=443

Answer 1

Here is the code to rotate the overlay view of camera

cameraOverlayView.transform = CGAffineTransformMakeRotation(-3.141592/2);

and it's for scale transform:

cameraController.cameraViewTransform=CGAffineTransformScale(cameraController.cameraViewTransform, 1, 1.25);
