swift addTarget 傳參

swift 無法像js那樣直接傳入參數. 需要借助tag傳參:

ListBtn.addTarget(self, action: "Detail:", forControlEvents: .TouchUpInside)

函數名中增加 ":" 字符

咱函數中通過傳入這個元素來實現傳值:

func Detail(sender:UIButton){
        var DeailVc = DetailViewController()
        DeailVc.Id = sender.tag
        self.presentViewController(DeailVc, animated: true, completion: nil)
    }
