如何在MPmovieviewController中显示.srt / subtitle文件

Question

我正在使用MPMovieViewController播放器在我的应用中显示视频，但也需要显示.Srt

我使用了以下代码

    if(self.livePlayer)
    {
        [self.livePlayer.view removeFromSuperview];
        [self.livePlayer stop];
        self.livePlayer=nil;
    }
    self.livePlayer = [[MPMoviePlayerController alloc] init];

    [self.view addSubview:self.livePlayer.view];
    self.livePlayer.view.frame = CGRectMake(5.0, 64.0, [[UIScreen mainScreen] bounds].size.width - 10.0, viwVideo.frame.size.height - 10.0);
    self.livePlayer.view.autoresizingMask=UIViewAutoresizingFlexibleWidth;
    [self.livePlayer.view setTranslatesAutoresizingMaskIntoConstraints:true];

    self.livePlayer.controlStyle = MPMovieControlStyleDefault;
    self.livePlayer.movieSourceType = MPMovieSourceTypeStreaming;
    self.livePlayer.shouldAutoplay = NO;
    frame = self.livePlayer.view.frame;
