一. AVAudioPlayer：
声明音乐控件AVAudioPlayer，必须声明为全局属性变量，否则可能不会播放，AVAudioPlayer只能播放本地音乐
//获取音乐文件路径
NSURL *soundUrl = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:_fileName ofType:@"mp3"]]; if (!_BGMPlayer) { _asset = [[AVURLAsset alloc] initWithURL:soundUrl options:nil];
//实例化音乐播放控件
_BGMPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:_asset.URL error:nil];
}
if (_BGMPlayer != nil) {
//缓冲播放
_BGMPlayer.delegate = self;
[_BGMPlayer prepareToPlay];
_BGMPlayer.numberOfLoops = -;
[_BGMPlayer play];
}else{
NSLog(@"初始化失败");
}
二. AVURLAsset
创建一个由URL标识的代表任何资源的asset对象
_asset = [[AVURLAsset alloc] initWithURL:soundUrl options:nil];
//实例化音乐播放控件
_audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:_asset.URL error:nil];
三. AVAudioPlayerDelegate
/* audioPlayerBeginInterruption: is called when the audio session has been interrupted while the player was playing. The player will have been paused. */
//产生中断后调用这个函数，通常暂停播放
- (void)audioPlayerBeginInterruption:(AVAudioPlayer *)player
{
[self.playerpause];
} /* audioPlayerEndInterruption:withOptions: is called when the audio session interruption has ended and this player had been interrupted while playing. */
/* Currently the only flag is AVAudioSessionInterruptionFlags_ShouldResume. */
//恢复中断后调用这个函数，继续播放
- (void)audioPlayerEndInterruption:(AVAudioPlayer *)player withOptions:(NSUInteger)flags
{
[self.playerplay];
} //解码出错后调用这个函数
- (void)audioPlayerDecodeErrorDidOccur:(AVAudioPlayer *)player error:(NSError *)error //播放结束后调用这个函数
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
