Click inside swift 2.2 OSX

Question

I am having multiple controls like NSTextfields and NSButtons. I couldn't find a solution for touch up inside events in swift 2.2. I tried it with the new selectors but I don't know how to handle touch events with them... Here is my code:

override func viewDidLoad() {
    textfield.action = #selector(myAction)
    button.action = #selector(myAction)
}

func myAction(sender: NSView)
{
    print("aktuell: \(sender)")
    currentObject = sender
}

I am not familiar with the new version of Swift 2.2 so I have no idea how to handle the touch events. I also tried to handle it over the delegate methods but this also didn't work because I have no method for the control if its being touched.

In the older versions of swift I had something like:

button.addTarget(self, action: Selector("actionMethod"), forControlEvents: UIControlEvents.TouchUpInside)

Error when trying to add the addTarget function:

Value of type 'NSButton' has no member 'addTarget'

But I can't find this in swift 2.2 and there is an error if I am trying to use it. Thanks for help!

I am using OSX not iOS but this should be the same...

You need to set the NSButton's action. For example:

let button = NSButton()
button.target = self
button.action = #selector(someAction)

From NSButton Class Reference:

NSButton is a subclass of the NSControl class. An NSButton object sends an action message to a target object, such as a view controller, when the button is clicked.

Does this work for textfields as well? – Tom el Safadi May 28 '16 at 01:27

Are you able to translate it to swift? I don't understand obj.-c. Thanks for the answer! – Tom el Safadi May 28 '16 at 01:29

@Anokrize No, you should learn how to convert Obj-C to Swift. If I answered your question please accept my answer. – Daniel Storm May 28 '16 at 01:30

Swift2.2 deprecates using strings for selectors and instead introduces new syntax:#selector.

For example:

button.addTarget(self, action: #selector(actionMethod), forControlEvents: .TouchUpInside)

I can't add the addTarget function somehow. – Tom el Safadi May 28 '16 at 01:01
see error edit above – Tom el Safadi May 28 '16 at 01:06
maybe you should check the button's class whether it is `UIControl` or the subclass of `UIControl`. – likumb May 28 '16 at 01:14
It is OSX I mentioned that already... – Tom el Safadi May 28 '16 at 01:15
oh sorry, the class `NSControl` is not have the `addTarget`method. try add the target `button.target = self`, `button.action = #selector(myAction)` . – likumb May 28 '16 at 01:25
