//Hide Keyboard

//1) Add DismissKeyboard function to resign keyboard on all textboxes
    func DismissKeyboard(){
        //forces resign first responder and hides keyboard
        // put all UItextFields
       [UItextfield].endEditing(true)
       
    }


//2) Add touchesBegan function to catch screen tap and resign keyboard
     //hide keyboard
   override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        //forces resign first responder and hides keyboard
        DismissKeyboard()
    }


//3) Put in ViewDidLoad

  //Looks for single or multiple taps
  //Replace "ViewController" with the name of ViewController
        let tap:UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(ViewController.DismissKeyboard))
        //Adds tap gesture to view
        view.addGestureRecognizer(tap)

         
//4) Add textFieldShouldReturn function. This is called when 'return' key pressed on any UITextField. return NO to ignore.
    func textFieldShouldReturn(textField: UITextField!) -> Bool     {
        textField.resignFirstResponder()
        return true;
    }

//5) Add Delegate to UITextFields to ViewController ([CNTRL] + Drag textfields to yellow viewcontroller and select delegate)
