How to do number keypad with done button in Swift 2.0? - ios

Question

I've tried lots of numeric keyboard with done button, it's not found a correct answer in SWIFT 2.0.

Answer 1

You can add done button above keyboard using toolbar
override func viewDidLoad() {
super.viewDidLoad()
let tooBar: UIToolbar = UIToolbar()
tooBar.barStyle = UIBarStyle.BlackTranslucent
tooBar.items=[
UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: self, action: nil),
UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: self, action: "donePressed")]
tooBar.sizeToFit()
yourTextFeild.inputAccessoryView = tooBar
}
func donePressed () {
yourTextFeild.resignFirstResponder()
}
It will look like this

Without toolbar, I'd added the done button in the Return key place itself by the following steps,
Create a custom Return button as below
let mobilePadNextButton = UIButton(type: UIButtonType.custom)
In viewdidload, design it. Here I'm designing Next button as I need Next instead of Done.
mobilePadNextButton.setTitle("Next", for: UIControlState())//Set Done here
mobilePadNextButton.setTitleColor(UIColor.black, for: UIControlState())
mobilePadNextButton.frame = CGRect(x: 0, y: 163, width: 106, height: 53)
mobilePadNextButton.adjustsImageWhenHighlighted = false
mobilePadNextButton.addTarget(self, action: #selector(self.mobilePadNextAction(_:)), for: UIControlEvents.touchUpInside)
Add Keyboad notification
func textFieldDidBeginEditing(_ textField: UITextField) {
NotificationCenter.default.addObserver(self, selector: #selector(ViewController.keyboardWillShow(_:)), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
}
func keyboardWillShow(notification:NSNotification){
if mobileNoTxtFld.isFirstResponder
{
DispatchQueue.main.async { () -> Void in
self.mobilePadNextButton.isHidden = false
let keyBoardWindow = UIApplication.shared.windows.last
self.mobilePadNextButton.frame = CGRect(x: 0, y: (keyBoardWindow?.frame.size.height)!-53, width: 106, height: 53)
keyBoardWindow?.addSubview(self.mobilePadNextButton)
keyBoardWindow?.bringSubview(toFront: self.mobilePadNextButton)
UIView.animate(withDuration: (((notification.userInfo! as NSDictionary).object(forKey: UIKeyboardAnimationCurveUserInfoKey) as AnyObject).doubleValue)!, delay: 0, options: UIViewAnimationOptions.curveEaseIn, animations: { () -> Void in
self.view.frame = self.view.frame.offsetBy(dx: 0, dy: 0)
}, completion: { (complete) -> Void in
print("Complete")
})
}
}
else
{
self.mobilePadNextButton.isHidden = true
}
}
Here, you can do the done actions
func mobilePadNextAction(_ sender : UIButton){
//Click action
}
The UI will looks like below,
