iOS 16场景方向问题

Question

当我试图在我的控制器上只允许纵向时，我总是收到这个错误： Error Domain=UISceneErrorDomain Code=101 “视图控制器不支持请求的方向。请求：landscapeLeft；支持：纵向” UserInfo={NSLocalizedDescription=视图控制器不支持请求的方向。要求：景观左；支持：纵向}

I called this method:
func updateOrientation(orientation: UIInterfaceOrientationMask) {
        if #available(iOS 16, *) {
            DispatchQueue.main.async {
                let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene
                self.setNeedsUpdateOfSupportedInterfaceOrientations()
                self.navigationController?.setNeedsUpdateOfSupportedInterfaceOrientations()
                windowScene?.requestGeometryUpdate(.iOS(interfaceOrientations: orientation)) { error in
                    print(error)
                    print(windowScene?.effectiveGeometry )
                }
            }
        }
    }

Did someone face the same issue ?

这看起来像是一种解决方法，但它解决了我的问题。

诀窍是在需要旋转时更新 AppDelegate 支持的方向。

在您的 AppDelegate 中：

    var orientation: UIInterfaceOrientationMask = .all
    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
         return orientation
    }

然后在你的控制器中：

 static func SwitchOrientation(orientation : UIInterfaceOrientationMask, viewController : UIViewController){
 
    
    
    if #available(iOS 16.0, *) {
        (UIApplication.shared.delegate as? AppDelegate)?.orientation = orientation
                            
        let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene
        windowScene?.requestGeometryUpdate(.iOS(interfaceOrientations: orientation))

        UIApplication.navigationTopViewController()?.setNeedsUpdateOfSupportedInterfaceOrientations()
        
        DispatchQueue.main.async {
                    let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene
                    viewController.setNeedsUpdateOfSupportedInterfaceOrientations()
                    viewController.navigationController?.setNeedsUpdateOfSupportedInterfaceOrientations()
                    windowScene?.requestGeometryUpdate(.iOS(interfaceOrientations: orientation)) { error in
                        print(error)
                        print(windowScene?.effectiveGeometry ?? "")
                    }
                }
    

    } else{
        UIDevice.current.setValue(orientation, forKey: "orientation")
    }
  
}

是的，我遇到了同样的问题并解决了如下问题。提供的错误清楚地表明我们正在尝试旋转设备，我们限制它只能在应用程序之前某处的一种模式下使用。在我的例子中，我在 Appdelegate.swift 中实现了下面的方法

var myOrientation: UIInterfaceOrientationMask = .portrait

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask { return myOrientation }

所以限制它只能使用纵向模式，导致应用程序在横向模式下旋转失败。

通过改变所有人的方向，让它工作。

var myOrientation: UIInterfaceOrientationMask = .portrait

你可以这样试试，对我有用

- (void)forceOrientation:(UIDeviceOrientation)orientation {
    if (@available(iOS 16.0, *)) {
        UIInterfaceOrientationMask orientationMask = (1 << orientation);
        [self setNeedsUpdateOfSupportedInterfaceOrientations];
        UIWindowScene *windowScene = (UIWindowScene *) 
        [UIApplication sharedApplication].connectedScenes.allObjects.firstObject;
        for (UIWindow *windows in windowScene.windows) {
            [windows.rootViewController setNeedsUpdateOfSupportedInterfaceOrientations];
        }
        UIWindowSceneGeometryPreferencesIOS *geometryPreferences = [[UIWindowSceneGeometryPreferencesIOS alloc] initWithInterfaceOrientations:orientationMask];
        [windowScene requestGeometryUpdateWithPreferences:geometryPreferences errorHandler:nil];
    } else {
       [[UIDevice currentDevice] setValue:@(orientation) forKey:@"orientation"];
       [UIViewController attemptRotationToDeviceOrientation];
    }
}

在 Appdelegate 中尝试

• (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window { 返回 UIInterfaceOrientationMaskAll； }
