为什么我的UIButton的目标永远不会达到？

Question

    func setupNewBinderButton() {
    let binderButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
    binderButton.frame = CGRectMake(50, 384-25, 50, 50)
    binderButton.setTitle("Add", forState: UIControlState.Normal)
    binderButton.setTitleColor(UIColor.blackColor(), forState: UIControlState.Normal)
    binderButton.addTarget(self, action: "addBinderTapped", forControlEvents: UIControlEvents.TouchUpInside)
    binderButton.userInteractionEnabled = true
    self.view.addSubview(binderButton)
    }



func addBinderTapped() {
    println("hi")
    abort()
}




override func viewDidLoad() {
super.viewDidLoad()

setupNewBinderButton()

我在此函数中设置的断点不会被命中。日志不会被击中。中止不会发生。

如何让我的UIButton响应Swift中的触摸？

Answer 1

使用这样，因为它需要绑定到IBAction

@IBAction func addBinderTapped(sender: UIButton)
{
}

通过命令将此操作与按钮连接+拖动到情节提要按钮以绑定此功能。
