希望我为登录和注销做了所有工作。但是当我尝试注销时它工作正常。但是当我返回登录屏幕时，我的用户名/密码仍保留在那里。

需要

当我注销或返回登录屏幕时，我的文本字段应该是空的，该怎么办。

这是我的 VC.swift

struct storyboard {
    static let ShowLoginSegue = "sss"
}

@IBOutlet weak var userField: UITextField!


@IBOutlet weak var passField: UITextField!
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    self.userField.delegate = self
    self.passField.delegate = self
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


@IBAction func loginBut(sender: AnyObject) {
    
    
    
 let klak = ""
    let qwqw = ""
    
    if userField.text == klak && passField.text == qwqw
    {
        
        print("correct")
          performSegueWithIdentifier(storyboard.ShowLoginSegue, sender: nil)
        
    }
    else
    {
        
        print("wrong")
    }

提前致谢!
