to take a screen shot of the screen you want renderInContext

#include <QuartzCore/QuartzCore.h>


[Background.window.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

I think this works anyway..

That's not quite right. You have to create an offscreen context, render the key window's layer into it, and the get an image from that context:

  UIWindow* theWindow = [[UIApplication sharedApplication] keyWindow];
  UIGraphicsBeginImageContext(theWindow.bounds.size);
  [theWindow.layer renderInContext:UIGraphicsGetCurrentContext()];
  UIImage *windowImage = UIGraphicsGetImageFromCurrentImageContext();
  UIGraphicsEndImageContext();

I'm not sure what you are asking. You don't want to capture the whole screen, but only a part of it?

Is the region you're capturing a specific view? That would make it easier.
