title: How to fix "Protocol Not Implemented"
body: <p>When I make a new controller called <code>TestController</code>, I insert </p>
  
  <pre><code>&lt;UITableViewDelegate,UITableViewDataSource,UITextFieldDelegate,UISearchBarDelegate&gt;
  </code></pre>
  
  <p>to the interface of Test.h</p>
  
  <p>When I run the app on the simulator, there are many issues that say 
  "incomplete implementation" and "method in protocol not implemented"</p>
  
  <p>I know some method is not implemented, but which one? How do I know what method I should add?</p>
