Per the View Controller Programing Guide If you want to temporarily disable automatic rotation, avoid manipulating the orientation masks to do this. Instead, override the shouldAutorotate method on the initial view controller. This method is called before performing any autorotation. If it returns NO, then the rotation is suppressed. So you need to subclass ‘UINavigationController’, … Read more
The most important part of the documentation I found for this issue is: When the user changes the device orientation, the system calls this method on the root view controller or the topmost presented view controller that fills the window To make my app fully working for autorotation in iOS 6, I had to do … Read more
Use media queries to test the orientation, in the portrait stylesheet hide everything and show a message that the app only works on landscape mode. <link rel=”stylesheet” type=”text/css” href=”https://stackoverflow.com/questions/10975387/css/style_l.css” media=”screen and (orientation: landscape)”> <link rel=”stylesheet” type=”text/css” href=”css/style_p.css” media=”screen and (orientation: portrait)”> I think is best aproach
Figured it out. 1) subclassed UINavigationController (the top viewcontroller of the hierarchy will take control of the orientation.) did set it as self.window.rootViewController. – (BOOL)shouldAutorotate { return self.topViewController.shouldAutorotate; } – (NSUInteger)supportedInterfaceOrientations { return self.topViewController.supportedInterfaceOrientations; } 2) if you don’t want view controller rotate – (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait); } -(BOOL)shouldAutorotate { return NO; … Read more
For iOS 7 & 8: Objective-C: NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationLandscapeLeft]; [[UIDevice currentDevice] setValue:value forKey:@”orientation”]; Swift 3+: let value = UIInterfaceOrientation.landscapeLeft.rawValue UIDevice.current.setValue(value, forKey: “orientation”) I call it in – viewDidAppear:.
I had the same problem and found a solution that works for me. To make it work, it is not sufficient to implement – (NSUInteger)supportedInterfaceOrientations in your UINavigationController. You also need to implement this method in your controller #3, which is the first one to be portrait-only after popping controller #4. So, I have the … Read more
For iOS 7 – 10: Objective-C: [[UIDevice currentDevice] setValue:@(UIInterfaceOrientationLandscapeLeft) forKey:@”orientation”]; [UINavigationController attemptRotationToDeviceOrientation]; Swift 3: let value = UIInterfaceOrientation.landscapeLeft.rawValue UIDevice.current.setValue(value, forKey: “orientation”) UINavigationController.attemptRotationToDeviceOrientation() Just call it in – viewDidAppear: of the presented view controller.
