title: Explain Objective C retain cycle with real world example?
body: <p>I am reading about retain cycle that,  "A retain cycle can take a few forms, but it typically means that object A retains object B, and object B retains object A, but nothing else retains object A or B". But I'm not clear about that concepts. Please can anyone explain retain cycle with real world example.</p>
  
  <p>Thanks.</p>
