ios - 按下主页按钮或电源按钮时无法关闭 MPMoviePlayerViewController

Question

基本上，我有一个显示MPMoviePlayerViewControllerExtended的MainViewController ，并且我想在用户点击主页按钮或电源按钮时关闭MPMoviePlayerViewControllerExtended 。

我在 MPMoviePlayerControllerExtended.m 中试过这个：

-(void)viewWillDisappear {
     [self dismissMoviePlayerViewControllerAnimated];
}
-(void)viewDidDisappear {
     [self dismissMoviePlayerViewControllerAnimated];
}

但它不起作用，显然按下 Home 或 Power 按钮时不会调用它们。

任何帮助表示赞赏。

Answer 1

尝试添加:(BOOL)animated

-(void)viewWillDisappear:(BOOL)animated {
     [self dismissMoviePlayerViewControllerAnimated];
}
-(void)viewDidDisappear:(BOOL)animated {
     [self dismissMoviePlayerViewControllerAnimated];
}

也可能想包括

[super viewWillDisappear:animated]

和

[super viewDidDisappear:animated]

在那些地方

-(void)viewWillDisappear:(BOOL)animated {
     [self dismissMoviePlayerViewControllerAnimated];
     [super viewWillDisappear:animated]
}
-(void)viewDidDisappear:(BOOL)animated {
     [self dismissMoviePlayerViewControllerAnimated];
     [super viewDidDisappear:animated]
}

Answer 2

由于没有调用这两种方法，我不得不使用通知。

在MPMoviePlayerViewControllerExtended.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[NSNotificationCenter defaultCenter] addObserver:self 
                                          selector:@selector(dismissModalViewControllerAnimated:) 
                                          name:UIApplicationDidEnterBackgroundNotification                  
                                          object:nil];
}
