UIButton addtarget到另一个视图控制器

Question

我在另一个ViewController上的view添加一个button 。 我需要目标选择器指向该视图控制器：

//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)

我怎样才能使目标指向一个已经存在的ViewController （otherVC）？

Answer 1

弄清楚了

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