Solution

  • Easy to do (assuming self is an UIViewController):

    #import < QuartzCore/QuartzCore.h >

...

UIGraphicsBeginImageContext(self.view.bounds.size);

[self.view.window.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage* screenshot = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

    Now you have the screenshot in the variable screenshot and can put it into an UIImageView.
