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

{

[SingleTonTooldefaultMemory].musicIndex++;

if ([SingleTonTooldefaultMemory].musicIndex == [[SingleTonTooldefaultMemory].musicArraycount])

{

}

NSString * musicFilePath = [[NSBundlemainBundle] pathForResource:musicNameofType:@"mp3"]; //创建音乐文件路径

NSURL * musicURL= [[NSURLalloc] initFileURLWithPath:musicFilePath];

AVAudioPlayer * thePlayer = [[AVAudioPlayeralloc] initWithContentsOfURL:musicURLerror:nil];

thePlayer.delegate =self;

[thePlayerplay];

[thePlayersetVolume:1]; //设置音量大小

thePlayer.numberOfLoops =1;//设置音乐播放次数 -1为一直循环

[musicURLrelease];

[SingleTonTooldefaultMemory].thePlayer = thePlayer;

[[SingleTonTooldefaultMemory].playerArrayremoveAllObjects];

[[SingleTonTooldefaultMemory].playerArrayaddObject:thePlayer];

}
