不应该调用MPMoviePlayerPlaybackDidFinishNotification [英] MPMoviePlayerPlaybackDidFinishNotification gets called when it shouldn't

问题描述

根据Apple的MPMoviePlayerController doc：

According to Apple's MPMoviePlayerController doc:

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

MPMoviePlayerPlaybackDidFinishNotification - This notification is not sent in cases where the movie player is displaying in fullscreen mode and the user taps the Done button.

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。

Seems to me this is dead wrong. Using the code below, playerPlaybackDidFinish gets called when I tap the done button.

[[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全部通过回放的方式。当电影结束时，playerPlaybackDidFinish会被调用，但就像我说的那样，当你点击Done时它也被调用。

I need to distinguish between the user tapping the done button and the movie finishing all the way through playback. playerPlaybackDidFinish does get called when the movie ends, but like I said it also gets called when you tap Done.

推荐答案

这是怎么回事检查MPMoviePlayerPlaybackDidFinishReasonUserInfoKey，它是MPMoviePlayerPlaybackDidFinishNotification通知的一部分

Here is how you check the MPMoviePlayerPlaybackDidFinishReasonUserInfoKey which is part of the notification of MPMoviePlayerPlaybackDidFinishNotification

- (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
    }
}
