ios - UIButton 将目标添加到不同的 View Controller

Question

我正在向不同 ViewController 上的 view 添加一个 button。我需要目标选择器指向那个 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)

如何让目标指向一个已经存在的 ViewController(otherVC)？

Answer 1

想通了

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