1、声明播放对象
@property (nonatomic, strong) AVAudioPlayer *player;

2、//创建AVAudioPlayer对象

-(AVAudioPlayer *)player{
if (_player == nil) {
NSError *error = nil;

_player = [[AVAudioPlayer alloc] initWithContentsOfURL:self.url error:&error];

_player.volume = 1.0;

_player.delegate = self;

if (error) {
NSLog(@”player error:%@”,error);

}

}

NSLog(@”play”);

return _player;

}

3、//点击播放录音

– (IBAction)playRcd:(id)sender {
UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback; //外放

AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);

UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;//话筒

AudioSessionSetProperty (kAudioSessionProperty_OverrideCategoryDefaultToSpeaker,sizeof (audioRouteOverride),&audioRouteOverride);

[self.player play];

}

4、//AVAudioPlayer的代理方法，不销毁不能二次播放

– (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag{
NSLog(@”%s”,__func__);

self.player = nil;

}
