@interface ViewController() <AVAudioPlayerDelegate> 

@property (nonatomic, strong) AVAudioPlayer *audioPlayer; 

@end 

@implementation ViewController 

- (void)viewDidLoad

    [super viewDidLoad]; 

    _audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"ttt" ofType:@"mp3"]] error:nil]; 
_audioPlayer.delegate = self; 
} 

- (void)play:(id)sender 
{ 
    [_audioPlayer play]; 
} 

- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag 
{ 
    AVAudioSession *audioSession = [AVAudioSession sharedInstance]; 
    NSError *error = nil; 
    if (![audioSession setActive:NO withOptions:AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation error:&error]) { 
     NSLog(@"resume music player failed, error=%@", error); 
    } 
}
