IOS Hide the navigation bar when the onscreen keyboard appears

The iOS navigation bar is hidden when the on-screen keyboard is activated in my app. How can I prevent this? This happens when the user is in the search bar and also if the user clicks on it.

I was able to display the navigation bar on the search page as soon as the user clicks on cancel or search / complete editing, but the search bar then gets under the navigation bar.

I do not have a "hidden panel if keyboard appears" selected in the interface builder.

You can also just go to Xcode and uncheck the box:

Hide bars → "When the keyboard appears" and it works fines.

Try it,



override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillShowNotification:", name: UIKeyboardWillShowNotification, object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillHideNotification:", name: UIKeyboardWillHideNotification, object: nil)
}


override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)
    NSNotificationCenter.defaultCenter().removeObserver(self, name: UIKeyboardWillShowNotification, object: nil)
    NSNotificationCenter.defaultCenter().removeObserver(self, name: UIKeyboardWillHideNotification, object: nil)
}

 func keyboardWillShowNotification(notification: NSNotification) {
    self.navigationController?.navigationBarHidden = false
}

func keyboardWillHideNotification(notification: NSNotification) {
    self.navigationController?.navigationBarHidden = false
}
