UIImagePickerController using iOS 8 cameraViewTransform isn't scaling

Question

I have previously solved a camera overlay issue: like this

CGSize screenBounds = [UIScreen mainScreen].bounds.size;

CGFloat cameraAspectRatio = 4.0f/3.0f;

         


        

Answer 1

In iOS 8 you no longer need to scale if you want to fill the screen. So the unique thing you have to do is to comment the assignment:

//self.picker.cameraViewTransform

That is to say, self.picker.cameraViewTransform = CGAffineTransformMakeScale(1.0, 1.0) conforms to self.picker.view.frame automatically.

In conclusion, the work is already done for you by UIImagePickerController.
