ios - 如何单击位于 UITableView 下方的按钮

Question

比如说，我在 UITableView 下面有一个按钮，我怎样才能通过 UITableViewCell 单击按钮而不触发单元格单击事件:

我把按钮放在tableview后面的原因是我想看到并点击颜色设置为清晰的单元格下面的按钮，当我滚动表格时，按钮可以被没有的单元格覆盖清晰的颜色

Answer 1

我创建了一个示例项目并使其运行:

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.

    let tap = UITapGestureRecognizer(target: self, action: #selector(TableViewVC.handleTap))
    tap.numberOfTapsRequired = 1
    self.view.addGestureRecognizer(tap)
}

func handleTap(touch: UITapGestureRecognizer) {
    let touchPoint = touch.locationInView(self.view)
    let isPointInFrame = CGRectContainsPoint(button.frame, touchPoint)

    print(isPointInFrame)

    if isPointInFrame == true {
        print("button pressed")
    }
}

要检查按钮是否真的被按下，我们需要使用长按手势:

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.

    let tap = UILongPressGestureRecognizer(target: self, action: #selector(TableViewVC.handleTap))
    tap.minimumPressDuration = 0.01
    self.view.addGestureRecognizer(tap)
}


func handleTap(touch: UILongPressGestureRecognizer) {
    let touchPoint = touch.locationInView(self.view)

    print(" pressed")
    if touch.state == .Began {
        let isPointInFrame = CGRectContainsPoint(button.frame, touchPoint)
        print(isPointInFrame)

        if isPointInFrame == true {
            print("button pressed")
            button.backgroundColor = UIColor.lightGrayColor()
        }
    }else if touch.state  == .Ended {

        button.backgroundColor = UIColor.whiteColor()
    }
}
