问题从网址播放声音

Question

我正在制作一款需要在循环中播放声音的Iphone应用。声音将来自HTTP链接，如下所示：

• Link 1
• Link 2
• Link 3
• Link 4
• Link 5
• Link 6
• Link 7
• Link 8

实际上有三个按钮循环，全部播放并停止。我可以做一次点击全部播放循环，但当我点击其他按钮应用程序将崩溃。我怎么能解决这个问题。我的代码是下面resultArrayFinal是一个全球阵列所有上述声音链接存储。

-(void)replayVedio
{
DataClass *obj=[DataClass getInstance];

NSURL *url = [NSURL URLWithString:obj.soundInfo];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[moviePlayer setControlStyle:MPMovieControlStyleDefault];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayer];


[moviePlayer prepareToPlay];
[moviePlayer play]; 

}

- (void) moviePlayBackDidFinish:(NSNotification*)notification 

{

 MPMoviePlayerController *player = [notification object];

 [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:player];

if(_globle==1)
{

    [self replayAudio];

}
else if(_globle==2)
{

    DataClass *obj=[DataClass getInstance];
    obj.soundInfo=[resultArrayFinal objectAtIndex:count++];

    if (count==[resultArrayFinal count])
        count=0;

    [self replayAudio];

}

}

感谢。
