#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>

@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);
    }
}

@end
