不应该调用MPMoviePlayerPlaybackDidFinishNotification

Question

根据Apple的MPMoviePlayerController doc：

MPMoviePlayerPlaybackDidFinishNotification - 如果电影播放器​​以全屏模式显示并且用户点击完成按钮，则不会发送此通知。

对我来说这是错误的。使用下面的代码，当我点击完成按钮时，会调用pl​​ayerPlaybackDidFinish。

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerPlaybackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.player];

- (void) playerPlaybackDidFinish:(NSNotification*)notification
{
    NSLog(@"WHY?");
    self.player.fullscreen = NO;
}

我需要区分用户点击完成按钮和电影完成播放的所有方式。当电影结束时，会调用pl​​ayerPlaybackDidFinish，但就像我说的那样，当你点击Done时它也会被调用。

Answer 1

以下是检查MPMoviePlayerPlaybackDidFinishReasonUserInfoKey的方法，这是MPMoviePlayerPlaybackDidFinishNotification通知的一部分

- (void) playbackDidFinish:(NSNotification*)notification {
    int reason = [[[notification userInfo] valueForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] intValue];
    if (reason == MPMovieFinishReasonPlaybackEnded) {
        //movie finished playin
    }else if (reason == MPMovieFinishReasonUserExited) {
        //user hit the done button
    }else if (reason == MPMovieFinishReasonPlaybackError) {
        //error
    }
}

Answer 2

当电影一直播放到最后时，我正在使用以下内容来做某事：

- (void)playbackDidFinish:(NSNotification*)notification
{
    BOOL playbackEnded = ([[[notification userInfo] valueForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] intValue] == MPMovieFinishReasonPlaybackEnded);
    BOOL endReached = (self.player.currentPlaybackTime == self.player.playableDuration);

    if (playbackEnded && endReached) {
        // Movie Ended
    }
}

收到通知后，您可以查看播放器的endPlaybackTime。如果它是-1那么电影就会自然地完成。

对于流内容，您可以检查MPMoviePlayerPlaybackDidFinishNotification上userInfo内的MPMoviePlayerPlaybackDidFinishReasonUserInfoKey。

如果它等于MPMovieFinishReasonUserExited，那么用户就是停止播放内容了。

确保

    moviePlayer.repeatMode = MPMovieRepeatModeNone;
