title: Autosynthesized property 'delegate' will use synthesized instance variable '_delegate', not existing instance variable 'delegate'
body: <p>I'm following the guide <a href="http://www.hardcodedstudios.com/home/ryan-newsome/simpledelegatetutorialforiosdevelopment" rel="noreferrer">here</a> to create a custom delegate. It runs fine but I get the following warning in xcode</p>
  
  <blockquote>
    <p>DetailViewController.m:23:1: Autosynthesized property 'delegate' will
    use synthesized instance variable '_delegate', not existing instance
    variable 'delegate'</p>
  </blockquote>
  
  <p>Can anyone advise how to get rid of the warning</p>
