播放MPMoviePlayer时如何截屏？

Question

How can I take screenshot when playing the video in MPMoviePlayer? I am using the below code for take screenshot but the player screen is black color. 1)

- (UIImage*)captureScreenshot:(UIView *)view {
        CGRect screenRect = [[UIScreen mainScreen] bounds];
        UIGraphicsBeginImageContext(screenRect.size);

        CGContextRef ctx = UIGraphicsGetCurrentContext();
        [self.view.layer renderInContext:ctx];

        UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();

        UIImageWriteToSavedPhotosAlbum(viewImage, self, nil, nil);
        return viewImage;
    }

2) CGImageRef originalImage = UIGetScreenImage();

This is apple banned.

Please give any other way to get screenshot from the movie player. Please help me.

有点hacktastic，但你可以采取截图，抓住从电影播放器的缩略图（例如，作为建议在这里 ），并覆盖在第一第二。
