在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions中加入这句话    [[AVAudioSession sharedInstance]setCategory:AVAudioSessionCategoryPlayback error:nil];

- (void)viewDidLoad{    [super viewDidLoad];// Do any additional setup after loading the view, typically from a nib.       NSString * resourcePath = [[NSBundle mainBundle] pathForResource:@"SIMS_BreathingSpace_100215" ofType:@"mp3"];//    NSString * resourcePath = [[NSBundle mainBundle] pathForResource:@"time" ofType:@"mp3"];    //    NSString * resourcePath = [[NSBundle mainBundle] pathForResource:@"time" ofType:@"mp3"];    NSData  *data =[NSData dataWithContentsOfFile:resourcePath];    audioPlayer = [[AVAudioPlayer alloc]initWithData:data error:nil];    audioPlayer.delegate = self;    audioPlayer.volume = 0.8f;    [audioPlayer prepareToPlay];    }-(IBAction)play:(id)sender{    [audioPlayer play];}
