如何在TableView单元格中按住按钮时进行排序

Question

我有一个非常复杂的问题，其中按钮已经具有作为@objc函数的点击动作。我可能必须对cellForRow函数实现代码，但是仅当这些函数在起作用时，它将如何调用？

@objc func longPress(gesture: UILongPressGestureRecognizer) {
        if gesture.state == UIGestureRecognizer.State.began {
            print("Long Press")
            //Was trying to figure out how to add segue call here 
        }
    }

    func addLongPressGesture(){
        let longPress = UILongPressGestureRecognizer(target: self, action: #selector(longPress(gesture:)))
        longPress.minimumPressDuration = 0.75
        self.expandButton.addGestureRecognizer(longPress)
    }

Answer 1

您可以从表所在的ViewController向您要转到的View中的情节提要中添加序列。然后给它一个标识符并调用func performSegue(withIdentifier identifier: String, sender: Any?)

@objc func longPress(gesture: UILongPressGestureRecognizer) {
        if gesture.state == UIGestureRecognizer.State.began {
            print("Long Press")
            performSegue(withIdentifier: String "showFromLongPress", sender: nil)
        }
    }

当然用您在情节提要中指定的标识符替换标识符showFromLongPress。
