Take custom screenshot

[joe_mac_112283]

I am making an app where the user can stack text and images on top of an image view. I cannot figure out how to take a screenshot of only the image view capturing it and everything on top of it. The image view is usually about 250x320 but it can vary and be anywhere on the screen.

This is the code I'm working with:

UIGraphicsBeginImageContext(self.view.frame.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

I've been messing with this code for a while and can't figure out how to get it to work right. I am getting all kinds of weird results, and I cannot find a method that will take a CGPoint. I think that is what I'm missing.

Thank you very much...

This is what I am trying:

UIGraphicsBeginImageContext(self.view.frame.size);
CGContextRef theContext = UIGraphicsGetCurrentContext();
[self.view.layer renderInContext:theContext];

CGRect overDrawRects[] = {CGRectMake(10, 0, 1, Picture_ImageView.frame.size.height), CGRectMake(Picture_ImageView.frame.size.width - 11, 0, 1, Picture_ImageView.frame.size.height)};

[[UIColor clearColor] set];

for (int i = 0; i < 2; i++) {
UIRectFill(overDrawRects[i]);
CGContextSaveGState(theContext);
CGContextClipToRect(theContext, overDrawRects[i]);
CGContextTranslateCTM(theContext, -1, 0);
[Picture_ImageView.layer renderInContext:theContext];
CGContextRestoreGState(theContext);
}

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

It saves the entire screen. It does save the layers on top of my image view but I only want to take a screenshot of the screen where my image view is located. I have tried switching out self.view for Picture_ImageView and all kinds of variations of that with no success.
