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

Instead of checking each and every button, just use a generic way to handle this. Set all your button to the same IBAction method and implement that like:

@IBAction func btn_box(sender: UIButton)
{
    // Instead of specifying each button we are just using the sender (button that invoked) the method
    if (sender.selected == true)
    {
        sender.setBackgroundImage(UIImage(named: "box"), forState: UIControlState.Normal)
        sender.selected = false;
    }
    else
    {
        sender.setBackgroundImage(UIImage(named: "checkBox"), forState: UIControlState.Normal)
        sender.selected = true;
    }
}
