Are you trying to save an image of your active UIView into a file or
the photo library?

If so, here:

UIGraphicsBeginImageContext(pictureView.bounds.size);
[pictureView.layer renderInContext:UIGraphicsGetCurrentContext()];

UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

pictureView is the UIView that you want to save.
