E aí pessoal, blz?

Galera, como faço para quando o teclado aparece mostrar o input que estou editando?

Valeu!

Bom dia!!

Segue uma alternativa:

// MARK: Alinhar campos de acordo com teclado subindo

    

    // This code handles the scrolling when tabbing through input fields

    var KEYBOARD_ANIMATION_DURATION: CGFloat = 0.3

    var MINIMUM_SCROLL_FRACTION: CGFloat = 0.3

    var MAXIMUM_SCROLL_FRACTION: CGFloat = 0.8

    var PORTRAIT_KEYBOARD_HEIGHT: CGFloat = 200

    var LANDSCAPE_KEYBOARD_HEIGHT: CGFloat = 140

    

    // MARK: UITextField delegates

    

    func initMask(aMask:String) -> Void {

        self.mask = aMask

    }

    

    func textFieldDidBeginEditing(_ textField: UITextField) {

        

        let textFieldRect: CGRect = self.view.window!.convert(textField.bounds, from: textField)

        let viewRect: CGRect = self.view.window!.convert(self.view.bounds, from: self.view)

        let midline: CGFloat = textFieldRect.origin.y+0.5*textFieldRect.size.height

        let numerator: CGFloat = midline-viewRect.origin.y-MINIMUM_SCROLL_FRACTION*viewRect.size.height

        let denominator: CGFloat = (MAXIMUM_SCROLL_FRACTION-MINIMUM_SCROLL_FRACTION)*viewRect.size.height

        var heightFraction: CGFloat = numerator/denominator

        if heightFraction < 0.0 {

            heightFraction = 0.0

        } else if heightFraction > 1.0 {

            heightFraction = 1.0

        }

        let orientation: UIInterfaceOrientation = UIApplication.shared.statusBarOrientation

        if orientation == .portrait || orientation == .portraitUpsideDown {

            animatedDistance = floor(PORTRAIT_KEYBOARD_HEIGHT*heightFraction)

        } else {

            animatedDistance = floor(LANDSCAPE_KEYBOARD_HEIGHT*heightFraction)

            

        }

        var viewFrame: CGRect = self.view.frame

        viewFrame.origin.y -= animatedDistance!

        UIView.beginAnimations(nil, context: nil)

        UIView.setAnimationBeginsFromCurrentState(true)

        UIView.setAnimationDuration(TimeInterval(KEYBOARD_ANIMATION_DURATION))

        self.view.frame = viewFrame

        UIView.commitAnimations()

    }

    

    func textFieldDidEndEditing(_ textField: UITextField) {

        

        var viewFrame = self.view.frame

        viewFrame.origin.y += animatedDistance!

        UIView.beginAnimations(nil, context: nil)

        UIView.setAnimationBeginsFromCurrentState(true)

        UIView.setAnimationDuration(TimeInterval(KEYBOARD_ANIMATION_DURATION))

        self.view.frame = viewFrame

        UIView.commitAnimations()

    }

    

    func textFieldShouldReturn(_ textField: UITextField) -> Bool {

        textField.resignFirstResponder()

        return true

    }
