dismissModalViewControllerAnimated关闭我的背景音乐

Question

当视图打开时，我有背景音乐，即使我将视图切换到其他视图并返回到主视图，背景音乐仍在播放问题。但是当我后退按钮从

mainViewController *mainView =[[mainViewController alloc] initWithNibName:nil bundle:nil]; 
mainView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; 
    [self presentModalViewController:mainView animated:YES]; // this will flip from right 

当翻转回主菜单中更改我的代码

[self dismissModalViewControllerAnimated:YES]; // this will flip back from left 

，我的背景音乐是​​不是在玩。只是好奇为什么？如何解决它？出于某种原因，我将代码更改为[self dismissModalViewControllerAnimated：YES];因为我希望我的观点从其他方面反转回来。当MAINVIEW是使用此代码

- (void)viewDidLoad 
    { 
     [super viewDidLoad]; 
     NSString *pathFile = [[NSBundle mainBundle] pathForResource:@"Start" ofType:@"mp3"]; 
     player = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:pathFile] error:NULL]; 
     [player play]; 
    } 

停止，如果观点是改变

- (void) viewDidDisappear:(BOOL)animated 
{ 
    [player stop]; 
}
