MPMoviePlayerController停止按钮不起作用

Question

我试图使用相同的按钮来播放和停止我的电台流，我的按钮播放良好，然后当我按下它停止，它只停止几秒钟，然后开始播放。

这里是我使用的代码。

- (IBAction)playStream:(id)sender { 
self.buttonPressed.selected = !self.buttonPressed.selected; 

NSString *urlAddress = @"http://67.159.28.74:8730"; 
NSURL *url = [NSURL URLWithString:urlAddress]; 

MPMoviePlayerController *player = [[MPMoviePlayerController alloc]initWithContentURL:url]; 


player.movieSourceType = MPMovieSourceTypeStreaming; 



player.view.hidden = YES; 

self.myPlayer = player; 

[self.view addSubview:self.myPlayer.view]; 



if (player.playbackState == MPMoviePlaybackStateStopped){ 
    [self.myPlayer play];} 
else if (player.playbackState == MPMoviePlaybackStatePlaying){ 
    [self.myPlayer stop];} 

}

Answer 1

每次按下该按钮，创建电影播放器​​的新实例。因此，支票if (player.playbackState == MPMoviePlaybackStateStopped)将始终返回YES，从而启动电影。
