collectionviewcell pass data to relevant collectionview - ios

Question

I am using collectionview. In this collectionview I have a button and I have 2 different cells in it which is 2 different collectionviewcell. When I press the button I need to get text from its second cells. the second cell is register cell which contains username, email and password fields.
Here is code snippets.
This is LoginController
class LoginController: UIViewController, UICollectionViewDelegateFlowLayout, UICollectionViewDelegate, UICollectionViewDataSource {
******* I am taking of cell; If I do not do that then TextField returns nil *******
var registerController: RegisterControllerCell?
override func viewDidLoad() {
super.viewDidLoad()
UIApplication.shared.statusBarStyle = .lightContent
view.backgroundColor = UIColor.rgb(61, 91, 151)
******* and here is making cell is accessible *******
registerController = RegisterControllerCell()
setupComponents()
}
final func setupComponents() -> Void {
.... components set up here
}
******* this is the collectionview that should hold cells in it *******
lazy var collectionView: UICollectionView = {
let layout = UICollectionViewFlowLayout()
layout.scrollDirection = .horizontal
let view = UICollectionView(frame: .zero, collectionViewLayout: layout)
view.register(LoginControllerCell.self, forCellWithReuseIdentifier: loginCellId)
view.register(RegisterControllerCell.self, forCellWithReuseIdentifier: registerCellId)
view.translatesAutoresizingMaskIntoConstraints = false
view.bounces = false
view.showsHorizontalScrollIndicator = false
view.isPagingEnabled = true
view.layer.cornerRadius = 8
view.layer.masksToBounds = true
view.backgroundColor = .white
view.delegate = self
view.dataSource = self
return view
}()
#objc func hideKeyboard(){
self.view.endEditing(true)
}
********* HERE IS PROBLEM STARTS... this is the button that should return text of textfield when clicking occurs. *********
let rlButton: UIButton = {
let btn = UIButton()
btn.translatesAutoresizingMaskIntoConstraints = false
btn.setTitle("LOGIN", for: .normal)
btn.layer.cornerRadius = 5
btn.layer.masksToBounds = true
btn.backgroundColor = UIColor.brown
btn.addTarget(self, action: #selector(handleClick), for: .touchUpInside)
return btn
}()
#objc func handleClick(){
switch buttonState {
case .register?:
registerUser()
break
case .login?:
print("login")
break
case .none:
print("none of them")
break
}
}
********* here is should return the value *********
func registerUser() -> Void {
******** this should return a text but it is nil every time ********
let username = registerController?.username.text
print(username)
}
// collectionView stuff
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 2
}
// let colors: [UIColor] = [.black, .green]
let colors: [colorEnumerations] = [.white, .white]
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: loginCellId, for: indexPath) as? LoginControllerCell else {
fatalError("unresolved cell id")
}
if indexPath.item == 1 {
guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: registerCellId, for: indexPath) as? RegisterControllerCell else {
fatalError("unresolved cell id")
}
return cell
}
cell.backgroundColor = colors[indexPath.item].value
return cell
}
}
and this is the RegisterCell
class RegisterControllerCell: BaseCell {
override func setupComponents() {
registerComponents()
}
final func registerComponents() {
.... components set up
}
let holder: UIView = {
let vw = UIView()
vw.backgroundColor = .white
vw.translatesAutoresizingMaskIntoConstraints = false
return vw
}()
let seperator: UIView = {
let spr = UIView()
spr.translatesAutoresizingMaskIntoConstraints = false
spr.layer.borderWidth = 0.5
spr.layer.borderColor = UIColor.gray.cgColor
spr.backgroundColor = UIColor.gray
return spr
}()
let seperator2: UIView = {
let spr = UIView()
spr.translatesAutoresizingMaskIntoConstraints = false
spr.layer.borderWidth = 0.5
spr.layer.borderColor = UIColor.gray.cgColor
spr.backgroundColor = UIColor.gray
return spr
}()
let seperator3: UIView = {
let spr = UIView()
spr.translatesAutoresizingMaskIntoConstraints = false
spr.layer.borderWidth = 0.5
spr.layer.borderColor = UIColor.gray.cgColor
spr.backgroundColor = UIColor.gray
return spr
}()
******** I need to get its and others texts ********
let username: UITextField = {
let input = UITextField()
input.translatesAutoresizingMaskIntoConstraints = false
input.placeholder = "Username"
return input
}()
let email: UITextField = {
let input = UITextField()
input.translatesAutoresizingMaskIntoConstraints = false
input.placeholder = "Email"
return input
}()
let password: UITextField = {
let input = UITextField()
input.translatesAutoresizingMaskIntoConstraints = false
input.placeholder = "Password"
input.isSecureTextEntry = true
return input
}()
}
Thanks for your helps guys, I really need that.
A little not: Textfield is not nil by the way, the nil thing is its text, it is every time returns nil.
