Reload View after UIAlertController

Question

I have a signup screen with a phone number field. If the user type a too short phone number, I display an UIAlertController. After she dismisses the Alert, the user can't send her phone number again as the send button is tapped. Is there a way to reload the view when the alert is dismissed to make the button untapped? Thanks

    func present_alert(title:String, content : String){
    let myAlert = UIAlertController(title:title, message:content, preferredStyle:UIAlertControllerStyle.alert)
    let okAction = UIAlertAction(title: "Ok", style: UIAlertActionStyle.default, handler:nil)
    myAlert.addAction(okAction)
    self.present(myAlert, animated:true)
}

Answer 1

the main reason on button click you disabled the yourbutton sender.isEnabled = false, when ever the alert is presented again enable your button , surely works addyourbuttonName.isEnabled = true

if you want to clear the current textfield value then use yourtextfield.text = ""

let alertController = UIAlertController(title: “Simple”, message: “Simple alertView demo with Cancel and Ok.”, preferredStyle: UIAlertControllerStyle.alert)

let okAction = UIAlertAction(title: “OK”, style: UIAlertActionStyle.default) { (result : UIAlertAction) -> Void in
print(“OK”)
 yourtextfield.text = ""
 yourtextfield.becomeFirstResponder()
 addyourbuttonName.isEnabled = true
}


alertController.addAction(okAction)
self.present(alertController, animated: true, completion: nil)
