iOS Error: Supported orientations has no common orientation with the application (iPhone)

Question

使用iOS8.3

我有一个横向模式的视图，我正在尝试打开一个仅纵向视图控制器。每次我尝试打开它时，应用程序都会崩溃。

我读过这个official apple answer，它基本上建议执行以下操作：

在应用委托中：

@implementation AppDelegate

-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
        return UIInterfaceOrientationMaskAll;
    else  /* iphone */
        return UIInterfaceOrientationMaskAllButUpsideDown;
}

在我的控制器中：

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

所以我有，但我仍然收到此崩溃消息：

Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and [PUUIAlbumListViewController shouldAutorotate] is returning YES

在项目常规设置中我有以下内容（根据苹果的回答应该不会改变）：

我可以看到实际上正在调用这些函数，但没有任何帮助。有什么想法吗？

我之前阅读的一些问题：

How to force a UIViewController to Portrait orientation in iOS 6

iOS6: supportedInterfaceOrientations not working (is invoked but the interface still rotates)

Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES'

Answer 1

概要： application(_:, supportedInterfaceOrientationsForWindow) -> Int 确实会覆盖常规 > 部署信息。因此，一旦您在应用程序委托中提供 supportedInterfaceOrientationsForWindow ，您就可以完全忽略该 .plist 。请参阅有关 UIInterfaceOrientationMaskPortrait.

的注释

在 Obj-C 和 Swift 中以各种方式尝试了上面的代码，我唯一一次得到...

'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and [ViewController shouldAutorotate] is returning YES'

...是什么时候：

使用UIInterfaceOrientationPortrait代替UIInterfaceOrientationMaskPortrait（mask是这里的关键词）
或supportedInterfaceOrientations returns 未 supportedInterfaceOrientationsForWindow

A. 将此块放在 class 采用 UIApplicationDelegate 协议（通常是 AppDelegate.m 或 AppDelegate.swift） :

-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
        return UIInterfaceOrientationMaskAll;
    else  /* iphone */
        return UIInterfaceOrientationMaskAllButUpsideDown;
}

supportedInterfaceOrientations 将覆盖 部署信息 并允许在运行时动态区分 iPhone 和 iPad。

B. 将此块放置在 UIViewController subclass 中，您希望其具有特定的行为（通常是 CustomViewController.m 或 CustomViewController.swift):

Obj-C

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

Swift

override func supportedInterfaceOrientations() -> Int {
    let supported = UIInterfaceOrientationMask.Portrait.rawValue
    return Int(supported)
}

测试iOS8.4

呃，对我来说，这是我颤抖中的这条线main.dart让我感到震惊：

  await SystemChrome.setPreferredOrientations([DeviceOrientation.landscapeLeft]);
