仅从横向视图返回到纵向应用程序

Question

我有一个只能在纵向模式下工作的应用程序，但是，有一个视图需要同时支持纵向和横向模式。任何时候，我从这个视图返回应用程序的其余部分搞砸了。

需要支持两个方向的视图包含用于播放直播流的webview。

简单设置shouldAutorotateToInterfaceOrientation不起作用。与呈现模态视图控制器的伎俩既不。删除和插入根视图的技巧也不起作用。

我害怕使用[[UIDevice currentDevice] setOrientation：UIInterfaceOrientationPortrait]（这实际上工作），因为它是私人API。

Answer 1

我有一个应用程序，所有的纵向工作，只有一个视图与全屏照片支持横向方向。所以我提出这个观点全屏模态，并在我的FullscreenViewController.m

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{ 
    return ([[UIApplication sharedApplication] statusBarOrientation]); 
} 

希望这可能是有用的

Answer 2

实际上删除和插入这里提到不工作的窗口视图第一视图的方法！ iOS portrait only app returns from UIWebview youtube in landscape

我只是需要从某种原因不要求窗口子视图中的第一个视图。我需要自己提供根视图。

所以我的解决方案是实现在支持两个方向视图控制器下面的方法：

-(void)viewWillAppear:(BOOL)animated 
{ 
    m_b_avoid_landscape_orinetation = NO; 

    [super viewWillAppear:animated]; 
} 

-(void)viewWillDisappear:(BOOL)animated 
{ 
    m_b_avoid_landscape_orinetation = YES; 

    UIWindow *window = [[UIApplication sharedApplication] keyWindow]; 
    [[self getTabBar].view removeFromSuperview]; 
    [window addSubview:[self getTabBar].view]; 

    [super viewWillDisappear:animated]; 
} 

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation 
{ 
    if (m_b_avoid_landscape_orinetation) 
     return (toInterfaceOrientation == UIInterfaceOrientationPortrait); 
    else 
     return YES; 
} 

其中[自getTabBar]提供的作品作为窗口的子视图第一个视图我的自定义标签栏。

编辑因此，与iOS 6不再起作用。我使用了解决方案，使用新的supportedInterfaceOrientations方法插入和删除模态对话框，如其他地方所述。

-(void)goBack 
{ 
    m_b_avoid_landscpae_orinetation = YES; 

    UIViewController *viewController = [[UIViewController alloc] init]; 
    UIWindow *window = [[UIApplication sharedApplication] keyWindow]; 
    [window.rootViewController presentViewController:viewController animated:NO completion:^{ 
     [viewController dismissModalViewControllerAnimated:NO]; 
    }]; 

    [self.navigationController popViewControllerAnimated:YES]; 
} 

-(NSUInteger)supportedInterfaceOrientations 
{ 
    if (m_b_avoid_landscpae_orinetation) 
     return UIInterfaceOrientationMaskPortrait; 

    return UIInterfaceOrientationMaskAllButUpsideDown; 
} 

Answer 3

你可以使用[[UIDevice currentDevice] setOrientation:orientation]在viewWillAppear:或viewDidAppear:强制应用旋转到所需方向。但是，这是私人电话，并不确定苹果是否会批准你的应用程序：）（我的批准）。祝你好运！
