title: Cancel gesturerecognizer when touching UITableView
body: <p>I have a view with 2 tableview and several textfield, I have implemented an extension to hide the keyboard:</p>
  
  <p>The keyboard hides when I touch the screen but I would like to disable UITapGestureRecognizer when I touch the TableView, otherwise I can not interact with the cells.</p>
  
  <pre><code>extension UIViewController {
  
  func OcultarTecladoTocarPantalla() {
      let tap : UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIViewController.OcultarTeclado))
      view.addGestureRecognizer(tap)
  }
  @objc func OcultarTeclado() {
      view.endEditing(true)
  }
  </code></pre>
  
  <p>}</p>
