Answer 1

Swift 2 :

this is what is did to do every thing !

close keyboard with Done button or Touch outSide ,Next for go to next input.

First Change TextFiled Return Key To Next in StoryBoard.

override func viewDidLoad() {
  txtBillIdentifier.delegate = self
  txtBillIdentifier.tag = 1
  txtPayIdentifier.delegate  = self
  txtPayIdentifier.tag  = 2

  let tap = UITapGestureRecognizer(target: self, action: "onTouchGesture")
  self.view.addGestureRecognizer(tap)

}

func textFieldShouldReturn(textField: UITextField) -> Bool {
   if(textField.returnKeyType == UIReturnKeyType.Default) {
       if let next = textField.superview?.viewWithTag(textField.tag+1) as? UITextField {
           next.becomeFirstResponder()
           return false
       }
   }
   textField.resignFirstResponder()
   return false
}

func onTouchGesture(){
    self.view.endEditing(true)
}
