iPhone snapshot including keyboard

Question

I'm looking for the proper way to snapshot the entire iPhone screen including the keyboard.

i found some code to snapshot the screen:

CGRect screenCaptureRect = [UIScreen mainScreen].bounds;
UIView *viewWhereYouWantToScreenCapture = [[UIApplication sharedApplication] keyWindow];
//screen capture code
UIGraphicsBeginImageContextWithOptions(screenCaptureRect.size, NO, [UIScreen mainScreen].scale);
[viewWhereYouWantToScreenCapture drawViewHierarchyInRect:screenCaptureRect afterScreenUpdates:NO];
UIImage *capturedImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

but it doesn't capture the keyboard as well. it looks like the keyWindow doesn't include the keyboard view.

btw I need UIImage as final result, not UIView, so I can't use other snapshot API's.

Any ideas of to do that and with best performance?

Keyboard is placed in other window. And in iOS9 keyboard accessory placed in different one. So the best solution is to render all windows.

Here is working code:

- (UIImage*)fullScreenShot {
    CGSize imgSize = [UIScreen mainScreen].bounds.size;
    UIGraphicsBeginImageContextWithOptions(imgSize, NO, 0);
    for (UIWindow* window in [UIApplication sharedApplication].windows) {
        if (![window respondsToSelector:@selector(screen)] || window.screen == [UIScreen mainScreen]) {
            [window drawViewHierarchyInRect:window.bounds afterScreenUpdates:YES];
        }
    }
    UIImage* img = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return img;
}
