I am completely new here! Learning by the seat of my pants. Trying to create a login and Password screen with a label. I have a textfield for User Name, one for Password, a label that says "Please Login" and a button to push. Everything is fine until I get to the button. I drag the button to the screen and set it up how I want, but when I try to command left click drag the button to the code, I get no options to make it an action.
So it comes in as @IBOutlet var theButton: UIView! which is wrong. The only options I get is Outlet and Outlet Collections, I can type over UIView and make it UIButton.
So I manually type in :
@IBAction func theButton(sender: AnyObject) {
var usr = "debf"
var pw = "cando"
if theTextfieldUsername.text == usr && theTextfieldPassword.text == pw {
println("Login Sucessful")
theTextfieldUsername.resignFirstResponder()
theTextfieldPassword.resignFirstResponder()
}
else {
println("Login Not Sucessful. Please Signup")
theTextfieldUsername.resignFirstResponder()
theTextfieldPassword.resignFirstResponder()
}
}
And when I run it, it throws and exception and I can not figure out what the problem is! I get:
2014-10-24 17:45:23.096 UFMTest[4146:1713077] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UFMTest.ViewController 0x79c70990> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key theSubmitButt.'
theSubmitButt
was the name of the button the first time I made it, I've deleted it and redone it several times but I still get this.
Any suggestions?
Here is the entire code:

import UIKit
class ViewController: UIViewController {
@IBOutlet var theTextfieldUsername: UITextField!
@IBOutlet var theTextfieldPassword: UITextField!
@IBOutlet var theLabel: UILabel!
@IBAction func theButton(sender: AnyObject) {
var usr = "debf"
var pw = "cando"
if theTextfieldUsername.text == usr && theTextfieldPassword.text == pw {
println("Login Sucessful")
theTextfieldUsername.resignFirstResponder()
theTextfieldPassword.resignFirstResponder()
}
else {
println("Login Not Sucessful. Please Signup")
theTextfieldUsername.resignFirstResponder()
theTextfieldPassword.resignFirstResponder()
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
The problem is, even after you deleted theSubmitButt
code from from ViewController
, Storyboard is still trying to connect the button to theSubmitButt
.
To resolve that, check "Connection Inspector" out in Interface Builder, and disconnect it from theSubmitButt
by clicking x
button.
