Where is NSControl's addTarget() method?

Question

So I haven't looked at Swift/Cocoa in several years. I just created a simple macOS app using Xcode 10.0 and see that NSControl no longer has an addTarget(...) method. It looks like it was replaced by a target property of type id.

How do I go about adding handlers for things like button clicks now since I need to specify the action (e.g. click), object to be called, and the selector to call on that object.

Solution:

let statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
statusItem.button?.target = self
statusItem.button?.action = #selector(didClick(_:))

Right, the method based syntax foo.addTarget(self) has been replaced with the property based syntax foo.target = self. It still exists in UIKit because in Cocoa Touch you have to specify also the control event.

And all relevant NSControl subclasses have init methods to pass target and action

Thank you @vadian. Unfortunately, I'm still a bit confused as I'm not the one creating the button. How do I specify which method gets called, say for a click event, when I'm only indicating that the object to be called is `self` with `foo.target = self`? – RobertJoseph Sep 24 '18 at 14:34

There is also an `action` property to specify the selector. – vadian Sep 24 '18 at 14:39

Did `NSControl` have a `addTarget:` method? As far as I know, `NSControl` always had one target and a `setTarget:` method. – Willeke Sep 25 '18 at 11:13

It's still there... You might want to review the docs as refresher.

The question is about NSControl from Cocoa (macOS), not about UIControl from Cocoa Touch (iOS). – Martin R Sep 24 '18 at 14:25
