Swift 3中的自定义复选框 [英] Custom checkbox in swift 3

问题描述

快速入门

我在视图控制器上有两个复选框按钮，当单击单个复选框按钮（单个）时，选中和取消选中都可以，但是
的目的是当我选中 PICK复选框时，取消选中 Drop Check Box

I had two check box buttons on view controller, when click single check box button(Indvidual) it's check and uncheck working fine, but my aim is when I check "PICK" checkBox button uncheck the "Drop Check Box"

如果我可以选择PickUP checkBox，则应该取消选中
，如果选择Drop CheckBox PickUP，则应该取消选中
，但同时未选择

if I can select PickUP checkBox Drop should uncheck if select Drop CheckBox PickUP Should uncheck but its not happening its selecting Both

这是我的单张支票代码

@IBAction func PushButtonClick(_ sender: UIButton) {

        let buttontag = sender.tag


        if isChecked {
            sender.setImage(UIImage(named:"check1"), for: .normal)
            print("checked")


            isChecked = false
        }
        else {
            sender.setImage( UIImage(named:"uncheck1"), for: .normal)
            isChecked = true
            print("uncheck")

        }
    }

    @IBAction func DropButtonClick(_ sender: UIButton) {


        if isChecked {
            sender.setImage(UIImage(named:"check1"), for: .normal)
            print("checked")
            isChecked = false
        }
        else {
            sender.setImage( UIImage(named:"uncheck1"), for: .normal)
            isChecked = true
            print("uncheck")

        }

    }

如果一个复选框选中另一个复选框，则未选中如何解决此问题……..

if one check box check check other check box Is unchecked how to over come this problem........

推荐答案

步骤1

创建一个用于存储的按钮阵列按钮

create one button array for store the buttons

var buttonscheck = [UIButton]()

步骤2

页面加载将按钮添加到该数组中，例如

on page load add the buttons to that array, for e.g

 override func viewDidLoad() {
    super.viewDidLoad()
   buttonscheck.append(btnPick)
   buttonscheck.append(btnDrop)
}

以及为两个按钮创建通用功能，例如

as well as create the common func for both buttons, for e.g

 @IBAction func PushButtonClick(_ sender: UIButton) {

第3步

在分配支票之前，请删除先前选择的UIbutton，例如

before assign the check remove the previous selection of your UIbuttons, for e.g

 @IBAction func PushButtonClick(_ sender: UIButton) {

    // clear previous selection of your buttons
    for getbutton in buttonscheck {
     getbutton.setImage( UIImage(named:"uncheck1"), for: .normal)
    } 
  // finally set the selected image for your button and it will hold the current button
   sender.setImage(UIImage(named:"check1"), for: .normal)
 }
