AVAudioPlayer *_audio

//获取本地音乐

NSData *audioData=[NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"1"ofType:@"mp3"]];

_audio=[[AVAudioPlayer alloc]initWithData:audioData error:nil];//音量_audio.volume=1;//设置播放速率_audio.enableRate=YES;//1.0正常 0.5减半 2.0两倍_audio.rate=1;//设置声道//-1.0左声道,0.0双声道,1.0右声道_audio.pan=0.0;//如果音频没有播放,currentTime指从30秒位置开始播放//如果音频正在播放,currentTime指调到30秒的位置播放//currentTime可以理解为当前播放时间,获取播放时间时也是currentTime_audio.currentTime=30;//播放[_audio play];

//获取在线音乐

NSURL *url=[NSURL URLWithString:@"http://localhost:8080/downloadSrver/1.mp3"];

NSURLRequest*request=[NSURLRequest requestWithURL:url];

NSData*data=(NSData *)[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

_audio=[[AVAudioPlayer alloc]initWithData:data error:nil];

//根据播放状态暂停

if(_audio.playing==YES) {

[_audio pause];

[button setTitle:@“continue” forState:UIControlStateNormal];

}else{

[_audio play];

[button setTitle:@"pause"forState:UIControlStateNormal];

}

//停止播放

[_audio stop];
