What you need is:
Declare function userInteractionEnabled_ lib UIKitLib selector “setUserInteractionEnabled:” (obj_id as ptr, yesNo as Boolean) userInteractionEnabled_(myImageView.Handle, True)
As for iOSKit - it’s a different thing than iOSLib. IOSKit is available at https://github.com/kingj5/IOSKit (link also in my signature). If you are familiar with git I recommend you fork the project so you can pull updates when they are made available. The project has some examples included but all you need to do is copy the Modules folder into your project for everything to be available.
