title: OCMockito mocking calls with block
body: <p>I want to mock an object with the following message declaration:</p>
  
  <p><code>- (void)createWithCompletion:(void (^)(FuseResult *result, NSError *err)) completion;</code></p>
  
  <p>Is it possible to mock the block call this message has to handle?</p>
  
  <p>I read the <a href="https://github.com/jonreid/OCMockito/blob/master/Source/Tests/ArgumentCaptorTest.m" rel="nofollow">ArgumentCaptorTest</a> which has block but I wasn't sure if it's relevant.</p>
