You could, although base on the additional information you sent before, an IBOutlet may be a better choice. Keep in mind that there is no real "right way" here. Outlet vs action is simply a stylistic decision, although outlets are a bit more extensible and may make later refactoring a little easier. Bindings, on the other hand, carry both a coding, debugging, and performance overhead that may be unnecessary for simpler operations (or in any case where it isn't sensible to have a model object). I would finally add that bindings are not *wrong* for your example--they are simply the more complex choice. If you search the archives you will find developers who shun them religiously, and others who swear by them. I like them personally for many things, but avoid them in situations where they needlessly over-complexify my design. HTH, Keary Suska Esoteritech, Inc.
