using swift, textfield move up when keyboard appears

Question

In objective C, this two line simple code is use to scroll the text view upwards. Is there any simple code in SWIFT like this to scroll textfield upwards?? Kindly help me.

- (void)textFieldDidBeginEditing:(UITextField *)textField {
CGPoint scrollPoint = CGPointMake(0, textField.frame.origin.y);
[scrollView setContentOffset:scrollPoint animated:YES];
}

- (void)textFieldDidEndEditing:(UITextField *)textField {
[scrollView setContentOffset:CGPointZero animated:YES];
}

Are you saying that you can't just translate that into Swift and you want someone else to do it for you? — matt, Dec 04 '14 at 15:33
Please clarify your question. Do you not know how to write this same code in swift, or is it not working as expected? — cmyr, Dec 04 '14 at 16:45

Its better to use this:

override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        scrollView.scrollEnabled = true
    yourTextfield.addTarget(self, action: "textFieldShouldReturn:", forControlEvents: .EditingDidEndOnExit)
    yourTextfield2.addTarget(self, action: "textFieldShouldReturn:", forControlEvents: .EditingDidEndOnExit)
    ...


    yourTextfield.tag = 1
    yourTextfield2.tag = 2
    ...
}   

    func textFieldShouldReturn(textField: UITextField!) -> Bool {
            let nextTag = textField.tag + 1
            let nextResponder:UIResponder? = textField.superview?.viewWithTag(nextTag)
            if ((nextResponder) != nil) {
                nextResponder?.becomeFirstResponder()
                var scrollPoint: CGPoint = CGPointMake(0, textField.frame.origin.y - 50)
                scrollView.setContentOffset(scrollPoint, animated: true)
            } else {
                textField.resignFirstResponder()
                scrollView.setContentOffset(CGPointZero, animated: true)
            }
            return false
        }

Set delegate of your textfield and implement the below methods

func textFieldDidBeginEditing(textField: UITextField) {
        animateViewMoving(true, moveValue: 100)
}
func textFieldDidEndEditing(textField: UITextField) {
        animateViewMoving(false, moveValue: 100)
}

func animateViewMoving (up:Bool, moveValue :CGFloat){
    var movementDuration:NSTimeInterval = 0.3
    var movement:CGFloat = ( up ? -moveValue : moveValue)
    UIView.beginAnimations( "animateView", context: nil)
    UIView.setAnimationBeginsFromCurrentState(true)
    UIView.setAnimationDuration(movementDuration )
    self.view.frame = CGRectOffset(self.view.frame, 0,  movement)
    UIView.commitAnimations()
}

you can write code in this way -

let biginSel = #selector(LoginViewController.didBeginEditing(_:))
    NSNotificationCenter.defaultCenter().addObserver(self, selector: biginSel, name: UITextFieldTextDidBeginEditingNotification, object: usrNmFld)
