makeKeyAndVisible for secondary screen stops UIMenuController from appearing

I present a UIMenuController over a view to display a copy and paste menu popup. This works great, but recently I added external screen functionality to my app. When I present a view and add it to the external screen I call

...

 [extWindow setScreen:extScreen];
 [extWindow addSubview:viewController.view];
 [extWindow makeKeyAndVisible];

...

but the [extWindow makeKeyAndVisible]; appears to have the side effect of stopping my menu appearing in the view that is still on the iPad.

How can I remedy this?

Solution

  • UIMenuController does indeed display to the current key window - I'd not set it back to the main window. Moral of the story is to make sure the window you want the menu to appear in is key.
