Question

I’m trying to take a full screen image of the camera picture without having the overlay ontop.

In my overlay controller I have tried to hide the overlay with this lines of code:

[self.view setHidden:YES];
[self.view setNeedsDisplay];
CGImageRef screen = UIGetScreenImage();
UIImage* image = [UIImage imageWithCGImage:screen];
CGImageRelease(screen);
self.view.hidden = NO;

UIGetScreenImage still shows the overlay UI.

Is there any way to make this happen?

You’ll need to set the cameraOverlayView property of the UIImagePickerController instance and then use the takePicture method to get the current image. In your delegate, you need to implement:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [self closeImagePickerController];

    // Get the edited or original image
    UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
    if (image == nil)
        image = [info objectForKey:UIImagePickerControllerOriginalImage];

    // Do something with the image...
}

Apple made UIGetScreenImage() a private API again, so you’re not allowed to use that anymore.
