MPMoviePlayerController拍摄屏幕截图但仅显示黑屏

Question

我在播放MPMoviePlayerController时拍摄截图。完美保存屏幕截图但图像仅为黑色。我使用下面的代码。

UIGraphicsBeginImageContext(self.moviePlayerController.view.frame.size);
[self.moviePlayerController.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

{
    CGImageRef originalImage = UIGetScreenImage();
    CGImageRef videoImage = CGImageCreateWithImageInRect(originalImage, CGRectMake(0, 66, 320, 230));            
    UIImage *snapShotImage = [UIImage imageWithCGImage:videoImage];
    UIImageWriteToSavedPhotosAlbum(snapShotImage, nil, nil, nil);
    CGImageRelease(originalImage);                
    CGImageRelease(videoImage);  
}
