UIButton addtarget to a different view controller

Question

I'm adding a button to a view on a different ViewController . I need the target selector to point to that view controller:

//target is self which works only works where I created the button
testBTN.addTarget(self, action: "test:", forControlEvents: UIControlEvents.TouchUpInside)

//otherVC is being instantiated as a new view controller so it doesn't work
testbtn.addTarget(otherVC(), action: "test:", forControlEvents: UIControlEvents.TouchUpInside)

How can I get the target to point to an already existing ViewController (otherVC)?

Answer 1

figured it out

let otherVC = self.storyboard!.instantiateViewControllerWithIdentifier("otherIdentifier")
testbtn.addTarget(otherVC, action: "test:", forControlEvents: UIControlEvents.TouchUpInside)
