Swift - addTarget to UIButton inside a Subview - ios

Question

I have a problem with my UIButton. Just for basic understanding:
User taps on a button -> popUpView appears (UIView)
User taps on UIButton which is a SubView of popUpView -> popUpView dismisses
That is my code for that:
#objc func addWishButtonTapped(notification : Notification){
view.addSubview(popUpView)
popUpView.addSubview(popUpTextField)
popUpView.addSubview(wishButton)
// constrain popUpView
popUpView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
popUpView.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: -100).isActive = true
popUpView.heightAnchor.constraint(equalToConstant: 200).isActive = true
popUpView.widthAnchor.constraint(equalToConstant: view.frame.width - 85).isActive = true
// constrain wishButton
wishButton.centerXAnchor.constraint(equalTo: popUpView.centerXAnchor).isActive = true
wishButton.centerYAnchor.constraint(equalTo: popUpView.centerYAnchor, constant: 130).isActive = true
wishButton.heightAnchor.constraint(equalToConstant: 100).isActive = true
wishButton.widthAnchor.constraint(equalToConstant: 100).isActive = true
// constrain textField
popUpTextField.centerXAnchor.constraint(equalTo: popUpView.centerXAnchor).isActive = true
popUpTextField.centerYAnchor.constraint(equalTo: popUpView.centerYAnchor, constant: -50).isActive = true
popUpTextField.heightAnchor.constraint(equalToConstant: 40).isActive = true
popUpTextField.widthAnchor.constraint(equalToConstant: view.frame.width - 170).isActive = true
popUpView.transform = CGAffineTransform(scaleX: 1.3, y: 1.3)
popUpView.alpha = 0
UIView.animate(withDuration: 0.3) {
self.visualEffectView.alpha = 1
self.popUpView.alpha = 1
self.popUpView.transform = CGAffineTransform.identity
}
// make whishButton clickable
self.wishButton.addTarget(self, action: #selector(wishButtonTapped), for: .touchUpInside)
}
#objc func wishButtonTapped(){
print("test")
insertWhish()
dismissPopUpView()
}
Problem:
whishButton is not clickable and I have no idea why.. I'm stuck on this for a while now so I am grateful for any help, thanks :)
UPDATE
This is my View Hierarchy:
Really weird, because the selected UIImage should actually be the UIButton which is in my case behind it (100x100 square). I definitely declared my whishButton as an actual UIButton()

Answer 1

first, try whit this line
self.popUpView.bringSubviewToFront(whishButton)
and if its necessary try this line
self.popUpView.sendSubview(yourImageBackGround)

Answer 2

Try to move buttons in storyboard

Answer 3

SOLVED
I solved my problem.. not in a very smooth way but it's working now. I just added the button as another subview of my normal UIView instead of adding it within my popUpView.

I guess, you don't create any instantiate of your root class globally.
class ViewController: UIViewController {
var viewController: MyViewController
override func viewDidLoad() {
super.viewDidLoad()
let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
myViewController =storyBoard.instantiateViewController(withIdentifier:"MyViewController") as! MyViewController
self.present(myViewController, animated:true, completion:nil)
myViewController.addWishButtonTapped(nil)
}
}
class MyViewController: UIViewController {
let popUpView = UIView()
let popUpTextField = UITextField()
let wishButton = UIButton()
override func viewDidLoad() {
super.viewDidLoad()
}
#objc func addWishButtonTapped(notification : Notification?){
view.addSubview(popUpView)
popUpView.addSubview(popUpTextField)
popUpView.addSubview(wishButton)
// constrain popUpView
popUpView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
popUpView.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: -100).isActive = true
popUpView.heightAnchor.constraint(equalToConstant: 200).isActive = true
popUpView.widthAnchor.constraint(equalToConstant: view.frame.width - 85).isActive = true
// constrain wishButton
wishButton.centerXAnchor.constraint(equalTo: popUpView.centerXAnchor).isActive = true
wishButton.centerYAnchor.constraint(equalTo: popUpView.centerYAnchor, constant: 130).isActive = true
wishButton.heightAnchor.constraint(equalToConstant: 100).isActive = true
wishButton.widthAnchor.constraint(equalToConstant: 100).isActive = true
// constrain textField
popUpTextField.centerXAnchor.constraint(equalTo: popUpView.centerXAnchor).isActive = true
popUpTextField.centerYAnchor.constraint(equalTo: popUpView.centerYAnchor, constant: -50).isActive = true
popUpTextField.heightAnchor.constraint(equalToConstant: 40).isActive = true
popUpTextField.widthAnchor.constraint(equalToConstant: view.frame.width - 170).isActive = true
popUpView.transform = CGAffineTransform(scaleX: 1.3, y: 1.3)
popUpView.alpha = 0
UIView.animate(withDuration: 0.3) {
self.visualEffectView.alpha = 1
self.popUpView.alpha = 1
self.popUpView.transform = CGAffineTransform.identity
}
// make whishButton clickable
self.wishButton.addTarget(self, action: #selector(wishButtonTapped), for: .touchUpInside)
}
#objc func wishButtonTapped(){
print("test")
insertWhish()
dismissPopUpView()
}
}
