Move subview up when keyboard displayed over textfields in subview - swift

Question

I have two textfields inside a subview and i am trying to move subview up when any of textfield clicked inside subview and keyboard appears. The problem is subview moves down when subview is up and i clicked on second textfield. It should hide when I touch any of the view except textfields.
The definition of my two textfield and subview;
#IBOutlet weak var emailTextField: UITextField!
#IBOutlet weak var passwordTextField: UITextField!
#IBOutlet weak var loginView: UIView!
The code in viewDidLoad
NotificationCenter.default.addObserver(self, selector:#selector(keyboardWillShow), name: .UIKeyboardWillShow, object: nil)
NotificationCenter.default.addObserver(self, selector:#selector(keyboardWillHide), name: .UIKeyboardWillShow, object: nil)
And two other functions which show and hide keyboard
func keyboardWillShow(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
if loginView.frame.origin.y == 0{
let height = keyboardSize.height
self.loginView.frame.origin.y += height
}
}
}
func keyboardWillHide(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
if loginView.frame.origin.y != 0 {
let height = keyboardSize.height
self.loginView.frame.origin.y -= height
}
}
}
I would like to know how can I avoid subview down when I click textfield while subview is up.

Just make the y-origin of view to zero when keyboard is down.
When you tap the other textField while keyboard is open this is .
func keyboardWillHide(notification: NSNotification) {
func keyboardWillShow(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
if loginView.frame.origin.y == 0{
let height = keyboardSize.height
self.loginView.frame.origin.y = -height
}
}
}
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
if loginView.frame.origin.y != 0 {
let height = keyboardSize.height
self.loginView.frame.origin.y = 0
}
}
}
