I am using the CosmicMind library for Material design and I am trying to set up basic textfields with some error checking but the documentation is not very good.
I have set up my text fields like the following:
@IBOutlet weak var userNameField: ErrorTextField!
userNameField.placeholder = "Enter Username"
userNameField.delegate = self
userNameField.error = "Text is too long" // App Crashes here
userNameField.errorColor = Color.red.base
App crashes with EXC_BAD_ACCESS
I validate my field like this:
func textField(textField: TextField, didChange text: String?) {
if textField == userNameField {
if validateUsername(text: textField.text!) {
userNameField.isErrorRevealed = true
} else {
userNameField.isErrorRevealed = false
}
}
}
Even if I remove that line, app crashes on userNameField.isErrorRevealed = true too.
I have created following code with same library which are you using, which are working fine. I have create textField programatically.
import UIKit
import Material
class ViewController: UIViewController {
fileprivate var emailField: ErrorTextField!
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = Color.grey.lighten5
emailField = ErrorTextField()
emailField.placeholder = "Email"
emailField.error = "Text is too long"
emailField.delegate = self
self.view.layout(emailField).height(40).width(200).centerVertically().centerHorizontally()
}
}
extension ViewController: TextFieldDelegate {
public func textFieldDidEndEditing(_ textField: UITextField) {
(textField as? ErrorTextField)?.isErrorRevealed = false
}
public func textFieldShouldClear(_ textField: UITextField) -> Bool {
(textField as? ErrorTextField)?.isErrorRevealed = false
return true
}
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
(textField as? ErrorTextField)?.isErrorRevealed = true
return true
}
}

I hope this will help you.
