Save UIView to iPad PhotoLibrary

Question

I'm creating an app where within a UIView subclass I have several UIImageView's holding UIImage's that the user has picked. I want to be able to allow the user to save the UIView to the PhotoLibrary so that those UIImageView's are saved as a sort of collage within this UIView. Would I need to have a UIImageView in place of the UIView to allow the code to save the whole area? or would I be able to use the UIView?

Thank you in advance!

This function does what you want except storage:

-(UIImage *)takeScreeShotOfView:(UIView *)view
{
    UIGraphicsBeginImageContext(CGSizeMake(1024, 748));
    CGContextRef context = UIGraphicsGetCurrentContext();
    [view.layer renderInContext:context];
    UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return img; 
}
