From what you’ve described and shown, your expectations for discardEditing are not correct. The method discardEditing is a method you implement, typically on your view controller that owns/manages your text field. There’s not really any good sample source using discardEditing I could find to point you to, but this one seems to give as best as can be.
https://sourceforge.net/p/skim-app/mailman/message/22781851/ <https://sourceforge.net/p/skim-app/mailman/message/22781851/> It sounds like you want to fill the field with the previous value that was in there, and while you could do it in a text field subclass, you’re probably better off managing that from its controller. By the time your sheet shows up, your text field is no longer performing any editing since it’s no longer the first responder. -- Gary L.
