I have an app with a WKWebView in it. In this app, I customize the options presented in the UIMenuController. The web view seems to add Copy and Define options to the menu no matter what I do. If I set myself as first responder and return NO for everything, I still get copy and define options. And I've implemented my own copy option that does special things depending on user preferences and what exactly is selected. Is there a way to remove these extra options?
Update: I've filed this as radar 18487289.
This appears to be fixed in iOS 13 beta 1.
