My app runs in portrait mode, but i want to show one screen in landscape mode only as it is a chart. What do i add to my uiviewcontroller to force it into landscape mode only?

screen. orientation. lock('landscape'); Will force it to change to and stay in landscape mode.
Set the supportedInterfaceOrientations property of specific UIViewControllers like this: class MyViewController: UIViewController { var orientations = UIInterfaceOrientationMask. portrait //or what orientation you want override var supportedInterfaceOrientations : UIInterfaceOrientationMask { get { return self.
From ios 10.0 we need set { self. orientations = newValue } for setting up the orientation, Make sure landscape property is enabled in your project. Save this answer.
I'm sorry but this answer will be very short: If you're using the UINavigationController, you can't. The answer @jer gives is therefore incorrect. The Apple documentation states:
All child view controllers in your UITabBarController or UINavigationController do not agree on a common orientation set.
I recently had this question answered on a bounty and my app rejected in the process. Read up on that here: How to constrain autorotation to a single orientation for some views, while allowing all orientations on others?
The only solution you have, is to throw away the UINavigationController and rewrite it with something of your own.

By presenting and dismissing a view controller modally you can force an orientation. Set animations to "NO" and you can do this without the user even realizing it occurred.
You can read more about this Josh's answer on Is there a documented way to set the iPhone orientation?
I consider it a bit of a hack, but I've successfully implemented code using this premise to force any device orientation.
