title: How can I determine which objects hold references to other objects that are causing memory leaks in objective-c?
body: <p>I have tried using the leaks tool, and "analyze" etc to find the leak, but it can't find it. Using allocations I can determine the objects which are not being released. </p>
  
  <p>I have noticed (by adding debugging statements in the dealloc method), that dealloc is not called for these objects.</p>
  
  <p>How can I determine which objects are holding references to these objects and preventing them from being released?</p>
