MPMoviePlayerController currentPlaybackTime 在设置 setCurrentPlaybackTime 时跳转

Posted 2023-03-08

【中文标题】MPMoviePlayerController currentPlaybackTime 在设置 setCurrentPlaybackTime 时跳转

【英文标题】：MPMoviePlayerController currentPlaybackTime jump while set setCurrentPlaybackTime

【发布时间】：2012-10-02 12:13:00

【问题描述】：

我使用 MPMoviePlayerController 作为我的媒体播放器。 我正在尝试使用我的方法来寻找（movieController 是 MPMoviePlayerController 的一个实例）

-(void)seekToTime:(NSTimeInterval)time

    [movieController setCurrentPlaybackTime:time];
    [NSTimer scheduledTimerWithTimeInterval:0.01 target:self selector:@selector(printCurrentPlaybacktime) userInfo:nil repeats:YES];

如您所见 - 搜索后我会快速打印出当前播放时间。 问题是——在开始时，当前播放时间是我设置的实际新时间。 一段时间后，当前播放时间是更改播放时间之前的旧时间， 过了一会儿，它又回到了新的实际时间。用户的结果是搜索滑块正在跳跃。

这是日志
