title: How to hide the keyboard in objective-c
body: <p>I have a simple view with a textbox and a UIButton.  When I click the UIButton I simply want to hide the keyboard that is currently in the view.  Is this a simple delegate I can add to the controller or something more complex?</p>
  
  <p>Of the answers that exist on SO already I haven't found one that has a full solution for this context.  Any help would be great!</p>
