UIButton addtarget到不同的视图控制器

Question

我在另一个button上向view添加了ViewController。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)

如何让目标指向已存在的ViewController（otherVC）？

Answer 1

想通了

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