Launching into portrait-orientation from an iPhone 6 Plus home screen in landscape orientation results in wrong orientation

Question

The actual title for this question is longer than I can possibly fit:

Launching an app whose root view controller only supports portrait-orientation but which otherw

Answer 1

I got same bug on my app, I figured it out with this solution

Firstly it didn't work but after some dig I have to do it on initial controller after splash screen.

Answer is OjbC language let me update it to Swift

override var shouldAutorotate: Bool {
    return true
}

override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    return .portrait
}

Don't forget that should on the initial view controller.

Answer 2

Setting the statusBarOrientation of the UIApplication seems to work for me. I placed it in the application:didFinishLaunchingWithOptions: method in the app delegate.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    application.statusBarOrientation = UIInterfaceOrientationPortrait;

    // the rest of the method
}

Answer 3

I had a similar issue is with my app runs both in landscape and portrait with a UITabBarController as root view controller.

Whenever the app was launched when in Landscape mode, the view was incorrect.

All I had to do: - remove rootview controller assignment in the XIB. - Manually add it in once the app is launched:

---

• (void)applicationDidFinishLaunching:(UIApplication *)application { application.statusBarHidden = YES;

  [self.window setRootViewController:self.tabBarController];

---

That fixed the problem.

Answer 4

I only want my app to open in landscape mode (and not exhibit the problem you describe above on the iPhone 6 Plus), so I set Landscape (left home button) and Landscape (right home button) as the only orientations allowed in my app's PLIST file. This fixes the orientation problem when my app opens. However, I need my app to support portrait mode for one view only since I display a UIImagePickerController in my app, which Apple requires to be shown in portrait mode on iPhone.

I was able to support portrait for that one view only, while keeping my app opening in landscape mode, by including the following code in AppDelegate:

-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {

        return UIInterfaceOrientationMaskAllButUpsideDown;

    } else {

        return UIInterfaceOrientationMaskAll;

    }

}

Answer 5

Please try the following code. Probably this problem caused by size of keywindow on landscape launch.

// in application:didFinishLaunchingWithOptions: ...

self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
[self.window setFrame:[[UIScreen mainScreen] bounds]]; //<- ADD!!

Answer 6

I had the same issue when launching our app in landscape on an iPhone 6 Plus.

Our fix was to remove landscape supported interface orientations from the plist via project settings:

and implement application:supportedInterfaceOrientationsForWindow: in the app delegate:

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    return UIInterfaceOrientationMaskAllButUpsideDown;
}

Apparently the information in your plist is to specify what orientations your app is allowed to launch to.
