Why iPhone sill rotate after I uncheck the device orientation (delete rotation from info.plist file)

Question

I don't check any device orientation on the Deployment Info page, that is, there is no entry in the Supported interface orientations on the Info.plist. However, the iPhone still can rotate to landscape. How can I disable iPhone rotation? Do I need to write some code in the view controller? Thanks in advance.

Answer 1

When you don't check any orientation, it defaults to all of them. To keep the orientation at only portrait, you must check the portrait only orientation.

Answer 2

You can toggle here in the device orientation section which orientation that you want your app to support:

Just set it to portrait and you'll be fine.
