I want to have a View with a textField an a send button above my keyboard, when the keyboard is shown. But this doesn't work.
I already implemented this in my code:
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIResponder.keyboardWillShowNotification, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(_ :)), name: UIResponder.keyboardWillHideNotification, object: nil)
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
tabBarController?.tabBar.isHidden = true
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
tabBarController?.tabBar.isHidden = false
}
// MARK: - Keyboard stuff
@objc func keyboardWillShow(_ notification: NSNotification) {
let keyboardFrame = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as AnyObject).cgRectValue
print("hier ist \(keyboardFrame!)")
UIView.animate(withDuration: 0.1) {
self.bottomConstraint.constant = keyboardFrame!.height
self.view.layoutIfNeeded()
}
}
@objc func keyboardWillHide(_ notification: NSNotification) {
UIView.animate(withDuration: 0.1) {
self.bottomConstraint.constant = 0
self.view.layoutIfNeeded()
}
}
Check out textField inputAccessoryView. There's a tutorial here that explains what you're trying to do.
