The best way to use checkbox - IOS swift

Question

I am going to work on a project that will use a lot of checkboxes. I found a solution like below, but I know this not right way.

 @IBAction func btn_box(sender:          


        

Answer 1

Please try this.

btn.setImage(UIImage(named: "uncheckImage"), for: UIControlState.normal)
btn.setImage(UIImage(named: "checkImage"), for: UIControlState.selected)

@IBAction func btn_box(sender: UIButton) {

     if btn.isSelected == true {

          btn.isSelected = false
     }
     else {

          btn.isSelected = true
     }
}
