UIViewController changes orientation while told not to do so

Question

I have a UIViewController where I override those 2 methods:

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask.Portrait
}

override func shouldAutorotate() -> Bool {
    return false
}

My device orientation is ticked for Portrait, Landscape Left & Right.

I cleaned the build folder.

My problem: when I go to landscape, the app changes the orientation.

Any idea what's wrong. I thought overriding those two methods should be enough but it seems not.

Answer 1

Since your view controller is embedded in a UINavigationController and overridding shouldAutorotate() in the respective view controller alone wont work since it checks the shouldAutoRotate() of the UINavigationController/UITabBarController and therefore you will have to create a extension of UINavigationController

extension UINavigationController {
    public override func shouldAutorotate() -> Bool {
        return visibleViewController.shouldAutorotate()
    }
}

And within the respective view controller wherever you want to lock the orientation as per your requirement override shouldAutoRotate()

override func shouldAutorotate() -> Bool {
    return false
}
