AVAudioPlayer连续播放音乐的代码（通到单例）
看不懂在下面留言，我会解释
- (void)audioPlayerDecodeErrorDidOccur:(AVAudioPlayer *)player error:(NSError *)error
{
[selforderToPlayBackGroundMusic];
}
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
[selforderToPlayBackGroundMusic];
}
-(void)orderToPlayBackGroundMusic
