How to enable/disable Alert action?
1
I want to enable the action of the alert only if the user has type in some input with the following codelines:
var alert: UIAlertController!
func alertBeitrageMelden(postId: String){
self.alert = UIAlertController(title: "Beitrag melden", message: "Wieso möchtest du den Beitrag melden?", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "Melden", style: .default) { (action) in
if let text = self.alert.textFields?.first?.text, text.count > 0 {
let postTime = Date().timeIntervalSince1970
let ref = Database.database().reference().child("gemeldeteBeitraege").child(postId)
ref.setValue(["postId": postId, "reason": text, "time": postTime])
ProgressHUD.showSuccess("Der Beitrag wurde gemeldet", interaction: false)
}
}
let cancelAction = UIAlertAction(title: "Abbrechen", style: .cancel) { (action) in
}
alert.addTextField { (textField) in
textField.placeholder = ""
textField.delegate = self
}
alert.addAction(defaultAction)
alert.addAction(cancelAction)
self.present(alert, animated: true) {
}
}
Here I check if the user typed in something:
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
if (textField.text?.count)! > 0 {
self.alert.actions[0].isEnabled = true
}else{
self.alert.actions[0].isEnabled = false
}
return true;
}
But its still not working.
Thanks in advance for your help!

Yes it works. this time, the action is enabled if there is one character inside the textfield but that makes no sense.

Do this
textField.addTarget(self, action: #selector(self.textEdited), for: .editingChanged)
@objc func textEdited(_ textField:UITextField) {
if textField.text!.count > 0 {
alert.actions.first?.isEnabled = true
}else{
alert.actions.first?.isEnabled = false
}
}
Add this line that will disable it initially
alert.actions.first?.isEnabled = false
self.present(alert, animated: true)
