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.
