UIGraphicsBeginImageContext(self.view.bounds.size);

to your respective value try it it will help you

Answer 2

The accepted answer is correct, however the screenshot is not in retina resolution. Using UIGraphicsBeginImageContextWithOptions and set its scale parameter 0.0f makes it capture in native resolution.

UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];
CGRect rect = [keyWindow bounds];
UIGraphicsBeginImageContextWithOptions(rect.size,YES,0.0f);
CGContextRef context = UIGraphicsGetCurrentContext();
[keyWindow.layer renderInContext:context];   
UIImage *capturedScreen = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Answer 3

Use This:

UIGraphicsBeginImageContext(rect.size);
[webView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
