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。每当我从这个视图返回时，应用程序的其余部分就会一团糟。

需要支持两个方向的视图包含用于播放实时流的 webview。

简单的设置 shouldAutorotateToInterfaceOrientation 不起作用。呈现模态视图控制器的技巧也没有。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] （实际上有效），因为它是私有 api。

我有一个应用程序可以在纵向上运行，只有一个带有全屏照片的视图支持横向。所以我以模态方式在我的 FullscreenViewController.m 中呈现这个全屏视图

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

希望这会有用

您可以使用[[UIDevice currentDevice] setOrientation:orientation]inviewWillAppear:或viewDidAppear:强制应用旋转到所需的方向。但是，这是私人电话，不确定 Apple 是否会批准您的应用程序 :)（我的应用程序已获得批准）。祝你好运！

实际上，这里提到的删除和插入窗口视图的第一个视图的方法确实有效！ 仅 iOS 纵向应用程序从 UIWebview youtube 以横向返回

我只需要出于某种原因不要在窗口子视图中要求第一个视图。我需要自己提供根视图。

所以我的解决方案是在支持两个方向的视图控制器中实现以下方法：

-(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;
}

[self getTabBar] 提供了我的自定义标签栏，它作为窗口子视图中的第一个视图。

编辑因此，对于 iOS 6，它不再起作用了。我使用了插入和删除模态对话框的解决方案，如其他地方提到的新的supportedInterfaceOrientations 方法。

-(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;
}
