How to get property of tapped button mapped from array? - swift

Question

I am trying to print properties from an array containing properties of a class when tapping on that button, I have read some answers but none are working. apparently println() use to work but it seems to have been depreciated. Below is the code in question:
this is the buttons class
class Buttons{
var nature = UIButton(type: UIButton.ButtonType.custom)
var name: String
init ( name: String) {
self.name = name
}
}
this is the array in the main class
var buttonsArray=[
Buttons(name: "below")
,
Buttons(name: "front")
,
Buttons(name: "right")
]
mapping:
for val in buttonsArray{
val.nature.frame = CGRect(x: 2, y: 10, width: 20, height:20)
val.nature.layer.cornerRadius = 0.5 * 0.12*bounds.size.width
val.nature.clipsToBounds = true
val.nature.backgroundColor = .blue
sceneView.addSubview(val.nature)
val.nature.adjustsImageWhenHighlighted = false
val.nature.addTarget(self, action: #selector(profileButtonClicked), for: UIControl.Event.touchDown)
val.nature.addTarget(self, action: #selector(profileButtonOut), for: UIControl.Event.touchUpInside)
val.nature.addTarget(self, action: #selector(profileButtonOut), for: UIControl.Event.touchDragExit)
}
assigned func
#objc func profileButtonClicked(button: self){
print(button.name)
}
I get an error in the function thought but the point is to print the tapped button name.
Thanks for your time

Answer 1

You can change the function parameter like
#objc func profileButtonClicked(button: Button){ print(button.name) }
For reference, you can see

You also mentioned you are getting error. It would be better if you share the error message.

Answer 2

Since you are getting bad access. In that case I have two solutions for you, I tested both and worked well.
First one, you need to modify your profileButtonClicked() function like below
#objc func profileButtonClicked(_ button: Buttons){
for x in buttonsArray {
if x.nature == button {
print(x.name)
break
}
}
}
Or I prefer this one,
Main class change would be,
var buttonList = [
ButtonTest(name: "below"),
ButtonTest(name: "front"),
ButtonTest(name: "right")]
for button in buttonList {
sceneView.addSubview(button)
}
You can replace Button class with ButtonTest,
class ButtonTest: UIButton {
var name: String
init(name: String){
self.name = name
super.init(frame:.zero)
self.frame = CGRect(x: 2, y: 10, width: 100, height:40)
self.layer.cornerRadius = 0.5 * 0.12 * 200
self.clipsToBounds = true
self.backgroundColor = .blue
//self.setTitle(name, for: .normal)
self.adjustsImageWhenHighlighted = false
//self.contentEdgeInsets = UIEdgeInsets(top: 10, left: 10, bottom: 0, right: -25.0)
//view.addSubview(val.nature)
self.addTarget(self, action: #selector(profileButtonClicked), for: UIControl.Event.touchDown)
//
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
#objc func profileButtonClicked(button: ButtonTest){
print(button.name)
}
}
