有没有办法采取的屏幕截图的MPMoviePlayerController是打(is there an

我想下面的步骤来捕捉屏幕截图，但得到的黑色底色为的MPMoviePlayerController

-(UIImage*)screenshot
{
 CGSize imageSize = [[UIScreen mainScreen] bounds].size;

CGFloat imageScale = imageSize.width / FRAME_WIDTH;

if (NULL != UIGraphicsBeginImageContextWithOptions)
    UIGraphicsBeginImageContextWithOptions(imageSize, NO, imageScale);
else
    UIGraphicsBeginImageContext(imageSize);

CGContextRef context = UIGraphicsGetCurrentContext();

for (UIWindow *window in [[UIApplication sharedApplication] windows]) 
{
    if (![window respondsToSelector:@selector(screen)] || [window screen] == [UIScreen mainScreen])
    {
        CGContextSaveGState(context);

        CGContextTranslateCTM(context, [window center].x, [window center].y);

        CGContextConcatCTM(context, [window transform]);

        CGContextTranslateCTM(context,
                              -[window bounds].size.width * [[window layer] anchorPoint].x,
                              -[window bounds].size.height * [[window layer] anchorPoint].y);

        [[window layer] renderInContext:context];

        CGContextRestoreGState(context);
    }
}

UIImage *image = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

return image;
}

Answer 1:

获取image从MPMoviePlayerController这样的action的button ：

-(void)getScreenShotOfMPMoviePlayerController:(MPMoviePlayerController *)mpPlayer
{
   UIImage *thumbnail = [mpPlayer thumbnailImageAtTime:yourMoviePlayerObject.currentPlaybackTime 
                       timeOption:MPMovieTimeOptionNearestKeyFrame];
}

编辑 ： Merge两个images作为取自一个图像MPMoviePlayerController与ScreenShot取自UIWindow 。

请参阅IOS-合并两图像-的，不同大小的链接合并。
