如何检测QTMovie停止播放？

Question

我做了以下事情 - 曾经在山狮上演过QTMovie，想在电影结束时收到通知。但通知从未被召唤过！谁能告诉我，我做错了什么？

- (void)playMovie:(QTMovie *)movie {
    [self.movieView.movie stop];

    if (movie) {
        self.movieView.movie = movie;
        [movie gotoBeginning];
        [movie play];

        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(stopMovie:) name:QTMovieDidEndNotification object:self];
    }
}


- (void)stopMovie:(NSNotification *)notification {
    NSLog(@"stop movie!");
    [[NSNotificationCenter defaultCenter] removeObserver:self name:QTMovieDidEndNotification object:nil];
}

尝试更改为以下内容（请注意对象参数）：

[[NSNotificationCenter defaultCenter] addObserver:self
    selector:@selector(stopMovie:)
    name:QTMovieDidEndNotification
    object:movie];
