ios - MPMoviePlayerController 停止时在 iOS 7 上崩溃

Question

我正在使用 MPMoviePlayerController 在我的应用中播放视频。它在 iOS 6 及更低版本之前运行良好。但是当我停止 MPMoviePlayer 对象时它在 iOS 7 上崩溃。

[player stop];

错误消息是:

-[__NSCFType _postNotificationName:object:]: unrecognized selector sent to instance 0x175927b0

是的，我也看到了这个错误。目前正在尝试弄清楚是否与“MPMoviePlayerPlaybackDidFinishNotification”存在某种冲突。

更新:我在 MPMoviePlayerPlaybackDidFinishNotification 通知方法中将 MPMovieplayer 实例设置为 NULL。将其移至我的电影播放器​​实例化方法修复了崩溃:

videoTrack = NULL

videoTrack = [[MPMoviePlayerController alloc]initWithContentURL:url];
