ios - 如何停止播放歌曲和播放新歌曲

Question

我正在开发应用程序，但有一个问题，当我单击按钮时，选定的索引歌曲开始播放，但是我想停止播放这首歌曲，然后播放下一首我给出索引的歌曲，这两首歌曲都开始播放。表示上一个连续播放，下一个也播放。
请指导我如何停止上一首歌，然后下一首才开始播放。
代码在这里

  - (IBAction)play:(id)sender
{
    [self.audioPlayer stop];
    self.audioPlayer = nil;
    self.audioPlayer.currentTime = 0;
    if(self.audioPlayer.playing ==YES)
    {
        self.audioPlayer.delegate=nil;
        [self.audioPlayer stop];
        self. audioPlayer=nil;
        NSLog(@"plat");
    }

    NSString *path=[[NSBundle mainBundle]pathForResource:sound.text ofType:@"mp3"];
    self.audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:
                        [NSURL fileURLWithPath:path] error:NULL];

    //self.audioPlayer = nil;
    [self.audioPlayer play];
}

试试这个:

   -(void)playSound
{
     NSString *path=[[NSBundle mainBundle]pathForResource:sound.text ofType:@"mp3"];
        self.audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:
                            [NSURL fileURLWithPath:path] error:NULL];
     [self.audioPlayer play];    
}
    - (IBAction)play:(id)sender
    {
    if (self.audioPlayer.playing == NO) 
    {
     [self playSound]; 
    }
     else
         if (self.audioPlayer.playing == YES) {
             [self.audioPlayer stop];
             [self playSound]; 

        }
    }
