title: iOS - UIBarButtonItem Identifier - option to create "settings" cogwheel button
body: <p>I want to create a UIBarButtonItem to represent the app's settings (cogwheel). Presently I can only find an option to create UIBarButtonItem (Interface Builder > Attributes Inspector > identifier) such as "Add" (+), "Edit", "Done", "Cancel" etc</p>
  
  <p>I can't find an option to create a settings (cogwheel) icon. Is there a way to do this in interface builder or through code?</p>
  
  <p>Or do I have to create an image and then the image ?</p>
