iOS - 检测电影已完成

Question

我正在使用 MPMoviePlayerViewController 播放电影，我创建了一个方法来检测电影何时结束然后运行一个方法:

- (void)movieFinishedWithSelector:(SEL)selectors {

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(selectors)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:[player moviePlayer]];
  }

并像这样使用此方法，但不起作用。

[self movieFinishedWithSelector:@selector(finished)];

我错过了什么吗？

selectors 参数已经是一个选择器。不要使用@selector:

- (void)movieFinishedWithSelector:(SEL)selector {
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:selector
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:[player moviePlayer]];
}
