title: Xcode Objective-c warnings "creating selector for nonexistent method" with OCUnit (SenTestingKit)
body: <p>I started getting getting warnings like the following in XCode when trying to write some unit tests with OCUnit (SenTestingKit).</p>
  
  <pre>
  warning: creating selector for nonexistent method 'myMethodName1:'
  warning: creating selector for nonexistent method 'myMethodName2:'
  ...
  warning: creating selector for nonexistent method 'release'
  warning: creating selector for nonexistent method 'retain'
  warning: creating selector for nonexistent method 'alloc'
  warning: creating selector for nonexistent method 'init'
  </pre>
  
  <p>Is it something I should worry about, or can I somehow disable these types of warnings by some compiler flag?</p>
