I've got a modal dialog with a couple of NSTextFields. Changes
weren't getting saved, so I thought I'd better call commitEditing on
the text field before retrieving its value with stringValue.
But when I call commitEditing on the NSTextField it gives the error:
-[NSTextField commitEditing]: unrecognized selector sent to instance
But there are no warnings from the compiler that commitEditing is an
invalid method.
What am I doing wrong?
Call -validateEditing instead, that should do what you want.
You don't get a warning because -commitEditing is implemented as a
category on NSObject, which means that NSTextField does effectively
implement it. It's just that -commitEditing is not the same as -
validateEditing.
