检测在“单元格”上单击了哪个“视图”

Question

我在一个 Cell 上有三个 UIImageView 当我点击单元格上的任何一个 UIImageView 时我想检测哪个被点击 onCellSelection，而不是放置一个UITapGestureRecognizer 每个 UIImageview

func SocialViewRow(address: SocialMedia)-> ViewRow<SocialMediaViewFile> {

let viewRow = ViewRow<SocialMediaViewFile>() { (row) in

    row.tag = UUID.init().uuidString
    }
    .cellSetup { (cell, row) in
        //  Construct the view
        let bundle = Bundle.main
        let nib = UINib(nibName: "SocialMediaView", bundle: bundle)

        cell.view = nib.instantiate(withOwner: self, options: nil)[0] as? SocialMediaViewFile
        cell.view?.backgroundColor = cell.backgroundColor
        cell.height =  { 50 }
        print("LINK \(address.facebook?[0] ?? "")")

        cell.view?.iconOne.tag = 90090

        //self.itemDetails.activeURL = address

        let openFace = UITapGestureRecognizer(target: self, action: #selector(QuickItemDetailVC.openFace))
        let openT = UITapGestureRecognizer(target: self, action: #selector(QuickItemDetailVC.openTwit))
        let you = UITapGestureRecognizer(target: self, action: #selector(QuickItemDetailVC.openYouYub))

         cell.view?.iconOne.addGestureRecognizer(openFace)

         cell.view?.iconTwo.addGestureRecognizer(openT)
         cell.view?.iconThree.addGestureRecognizer(you)



        cell.frame.insetBy(dx: 5.0, dy: 5.0)
        cell.selectionStyle = .none

    }.onCellSelection() {cell,row in

     //example   
    //print(iconTwo was clicked)


}


return viewRow
}

Answer 1

重写 touchesbegan 函数。每次用户触摸屏幕时都会调用此方法。每次调用时，检查触摸是否在图像所在的同一位置开始。

 override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
     let touch = touches.first!
     let location = touch.location(in: self)
     //check here, include code that compares the locations of the image
}

Location 将是一个 CGPoint。您应该能够获取图像边界的 CGPoints，然后确定这些边界内是否有 touchBegan。如果你想包括用户触摸的整个路径，也有一些方法可以做到，但开始的触摸应该足以满足你的需要。

使用UITapGestureRecogniser（或UIButton）会是更好的方法。这些类旨在完成这样的任务。

如果您仍想使用不同的方法，请将方法添加到您的单元格子类（将 imageView1, imageView2, imageView3 替换为您自己的属性）

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
  guard let touch = touches.first else { return }
  let point = touch.location(in: view)
  if imageView1.frame.containsPoint(point) {
    // code for 1st image view
  } else if imageView2.frame.containsPoint(point) {
    // code for 2nd image view
  } else if imageView3.frame.containsPoint(point) {
    // code for 3rd image view
  }
}
