iOS 7 通知中心未调用

Question

我已经使用这段代码来播放一些视频。并希望在完成播放时收到事件。但不使用通知中心获取事件。

我试过这段代码

    NSString * str=[[NSBundle mainBundle]pathForResource:@"iGreet" ofType:@"m4v"];

    NSURL * url=[NSURL fileURLWithPath:str];

    MPMoviePlayerController * movieController=[[MPMoviePlayerController alloc]initWithContentURL:url];
    movieController.controlStyle=MPMovieControlStyleFullscreen;
    [movieController.view setFrame:self.view.bounds];

    [movieController setMovieSourceType:MPMovieSourceTypeFile];
    movieController.shouldAutoplay=YES;

    [self.view addSubview:movieController.view];
    [movieController setFullscreen:YES animated:YES];
    [movieController play];


    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(onStop:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:movieController];

}

  -(void)onStop:(NSNotification*)notification
{


}

更改为:

[[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(onStop:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:movieController];

和

-(void)onStop:(NSNotification*)notification
{


}

它对我有用。
