Caveat: I don’t know the answer to what you’re asking, but I suspect you may be asking the wrong question. First of all, what does “does not work” mean? Second, looking at the documentation here: https://developer.apple.com/documentation/appkit/nscontrol <https://developer.apple.com/documentation/appkit/nscontrol> the “abortEditing” method is listed under “Managing the Field Editor”. I suspect it’s actually used internally to manage the relationship between the text field’s cell and the field editor, and not to manage the editing state of the control as a while. This method is probably just the wrong hammer for this nail. Third, what I think you’re looking for is “discardEditing”, which is a part of the NSEditor protocol, to which NSTextField conforms. However, I’m not entirely sure about timing, whether it’s reasonable to invoke in response to “attemptRecoveryFromError:…”. But maybe. Note that the documentation for NSEditor shows its methods as deprecated: https://developer.apple.com/documentation/appkit/view_management/nseditor <https://developer.apple.com/documentation/appkit/view_management/nseditor> I believe this is a documentation error. At some point, NSEditor was converted from an informal protocol to a formal protocol (so it would translate into Swift properly), and that causes this error in the documentation. If you look at the actual header file (NSKeyValueBinding.h), you can see that the formal NSEditor protocol has no deprecations: > @protocol NSEditor <NSObject> > > - (void)discardEditing; // … > - (BOOL)commitEditing; // … as well as the deprecations of the information protocol methods: > @interface NSObject (NSEditor) > - (void)discardEditing NS_DEPRECATED_MAC(10_0, API_TO_BE_DEPRECATED, "This is > now a method of the NSEditor protocol."); > - (BOOL)commitEditing NS_DEPRECATED_MAC(10_0, API_TO_BE_DEPRECATED, "This is > now a method of the NSEditor protocol."); _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
