iOS Screenshot part of the screen

Question

I have an App that takes a screenshot of a UIImageView with the following code:

-(IBAction) screenShot: (id) sender{

 UIGraphicsBeginImageContext(sshot.fram         


        

Answer 1

From this

UIGraphicsBeginImageContext(sshot.frame.size);
CGContextRef c = UIGraphicsGetCurrentContext();
CGContextTranslateCTM(c, 150, 150);    // <-- shift everything up to required position when drawing.
[self.view.layer renderInContext:c];
UIImage* viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);
