I am having multiple textfields and I won't to invoke an action method if the user clicks on a textfield, this is what I currently have:
override func mouseDown(theEvent: NSEvent) {
}
for the click event.
This is the action to which it should reference when a textfield is pressed:
func myAction(sender: NSView)
{
print("aktuell: \(sender)")
currentObject = sender
}
For buttons it is working with the action and selector but this does not work for textfields...
button.action = #selector(myAction)
Please give examples only in swift, I know that there are plenty of examples in obj.-c. Thanks!

Answer 1

Got it working with that:
1) Create a subclass of NSTextField.
import Cocoa
class MyTextField: NSTextField {
override func mouseDown(theEvent:NSEvent) {
let viewController:ViewController = ViewController()
viewController.textFieldClicked()
}
}
2) With Interface building, select the text field you want to have a focus on. Navigate to Custom Class on the right pane. Then set the class of the text field to the one you have just created.**
3) The following is an example for ViewController.
import Cocoa
class ViewController: NSViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override var representedObject: AnyObject? {
didSet {
// Update the view, if already loaded.
}
}
func textFieldClicked() -> Void {
print("You've clicked on me!")
}
}
