TextField in Xamarin IOS not allowing input

问题

I have an ios App created in Xamarin with Visual Studio on the Mac. I've modified SceneDelegate to load a UITabController that is not created on the Storyboard. I've done this to allow changing the number of tabs presented in some cases.

The UITabController is adding a View that is defined on the Storyboard. This view contains a TextField, this textfield does not allow text entry. When you tap it a keyboard does not appear.

Yes User Interaction Enabled is checked.

How can I fix this? Thanks, Gerry

回答1:

We need to assign the UIScene (actually a UIWindowScene) to the WindowScene property of the Window , so improve the code in SceneDelegate.WillConnect like following :

Window = new UIWindow(scene as UIWindowScene);


UIViewController vc = new MyTabController();
Window.RootViewController = vc;

Window.MakeKeyAndVisible();
