You should have a look a the original Apple Sample “SquareCam”. It shows how to save the image to the camera roll.
]]>if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)]) {
if ([[UIScreen mainScreen] scale] == 2.0) {
UIGraphicsBeginImageContextWithOptions(self.previewView.bounds.size, YES, 2.0);
} else {
UIGraphicsBeginImageContext(self.previewView.bounds.size);
}
} else {
UIGraphicsBeginImageContext(self.previewView.bounds.size);
}
[self.previewView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(viewImage, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
I just want to save a image of the whole thing that is displaying on the screen, the “live camera” plus the overlay image.
But with this code, I’m getting a completely black image as output.
Can you help me with this? Thank you so much 🙂
]]>MIT Licence. By the way. Most of the code you see here is based on the Apple Sample. So take into account that Licence.

What kind of license is your code under? I’d like to use a few pieces of it in some code of mine. But instead of drawing something on the face, I want to cut out the face and center it in a box. Since your AV setup is pretty good I’d love to use that.
