While typing on keyboard button tap doesn't get recognized - ios

Question

I've got a problem with my iOS application. I want to implement something like a MessagingViewController where you got a UITextView and Button (sendButton) below an UITableView. If a tap the textView, the keyboard appears, the View goes up.. so far so good.
But, if I am entering random text and tab/press the send button (independent of what should happen now) while typing or if the time gap between typing and Button tab is to small, the tap doesn't get recognized. If you try iMessage or WhatsApp this isn't a problem.
I don't know what to do, I also tried CocoaPods like SlackViewController or InputAccessoryView but it is always the same problem. While typing, the button tap doesn't get recognized. I tried it with the normal IBAction of a UIButton and UITapGestureRecognizer.
I hope somebody can help me, this problem makes the UX horrible.
Thanks a lot!!!
Edit: Here's an example where the Button is in an InputAccessoryView.
import UIKit
class MessagingViewController: UIViewController, UITableViewDataSource {
var messages: [String] = ["12", "32"]
var accessory: UIView!
var cancelButton: UIButton!
var charactersLeftLabel: UILabel!
var sendButton: UIButton!
#IBOutlet var tableView: UITableView!
#IBOutlet var messagesTextView: UITextView!
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
tableView.register(UINib(nibName: TableViewCell.className, bundle:nil),
forCellReuseIdentifier: TableViewCell.className)
addAccessoryView()
NotificationCenter.default.addObserver(self, selector: #selector(MessagingViewController.keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(MessagingViewController.keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return messages.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell", for: indexPath) as? TableViewCell
cell?.titleLabel.text = "Sender: \(indexPath.row): "
cell?.detailLabel.text = messages[indexPath.row]
return cell!
}
func addAccessoryView() {
let frame = CGRect(x:0, y:0, width: self.view.frame.width,height: 45)
accessory = UIView(frame: frame)
accessory.backgroundColor = UIColor.lightGray
accessory.alpha = 0.6
accessory.translatesAutoresizingMaskIntoConstraints = false
self.messagesTextView.inputAccessoryView = accessory
sendButton = UIButton(type: .custom)
sendButton.setTitleColor(UIColor.red, for: .normal)
sendButton.setTitle("Send", for: .normal)
sendButton.setTitleColor(UIColor.white, for: .disabled)
sendButton.addTarget(self, action: #selector(MessagingViewController.sendButtonTapped(_:)), for: .touchUpInside)
sendButton.showsTouchWhenHighlighted = true
sendButton.isEnabled = true
sendButton.translatesAutoresizingMaskIntoConstraints = false
accessory.addSubview(sendButton)
let sendTrailingConstraint = NSLayoutConstraint(item: sendButton, attribute: .trailing, relatedBy: .equal, toItem: accessory, attribute: .trailing, multiplier: 1.0, constant: -20)
accessory.addConstraint(sendTrailingConstraint)
let sendCenterYConstraint = NSLayoutConstraint(item: sendButton, attribute: .centerY, relatedBy: .equal, toItem: accessory, attribute: .centerY, multiplier: 1.0, constant: 0)
accessory.addConstraint(sendCenterYConstraint)
}
func sendButtonTapped(_ sender: UIButton) {
messages.append(messagesTextView.text)
messagesTextView.text.removeAll()
tableView.reloadData()
tableView.scrollToRow(at: IndexPath(row: messages.count - 1, section: 0), at: .bottom, animated: true)
}
func keyboardWillShow(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
if self.view.frame.origin.y == 0{
self.view.frame.origin.y -= keyboardSize.height
}
}
}
func keyboardWillHide(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
if self.view.frame.origin.y != 0{
self.view.frame.origin.y += keyboardSize.height
}
}
}
}

I just tested on my project, it's works without any problem, add your code to see what you did. (i can't comment so i put this as an answer)
