A logic that lets you save your view as image to your saved photos. Here are the steps to follow:

1. Add QuartzCore framework.

2. Add IBAction in your header.
- (IBAction)fooView;

3. In your implementation add your IBAction similar to your header file.

- (IBAction)fooView {
UIGraphicsBeginImageContext(self.view.bounds.size) ;
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);

4. Lastly make sure to call #import to your implementation. Then set your button to your method.
