title: Find where object is retained with ARC
body: <p>I have an object that is being retained more than necessary (most likely due to a property that is <code>strong</code> instead of <code>weak</code>). Big codebase, so it's hard to find where.</p>
  
  <p>How can I find all the lines in which this object is being retained when using ARC?</p>
  
  <p>If I weren't using ARC I guess I could simply override <code>retain</code> and check from where it's called. Can I do something similar with ARC?</p>
