你必须通过代码添加它。尝试这个:
// 1.create UIView programmetically var myView = UIView(frame: CGRectMake(100,100,100)) // 2.add myView to UIView hierarchy self.view.addSubview(myView) // 3. add action to myView let gesture = UITapGestureRecognizer(target: self,action: "someAction:") // or for swift 2 + let gestureSwift2AndHigher = UITapGestureRecognizer(target: self,action: #selector (self.someAction (_:))) self.myView.addGestureRecognizer(gesture) func someAction(sender:UITapGestureRecognizer){ // do other task } // or for Swift 3 func someAction(_ sender:UITapGestureRecognizer){ // do other task } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
