title: Will the instance class release if the member class still contain strong references?
body: <p>Let say my instance (<code>instA</code>) has a property called <code>(strong) NSString *text</code>.</p>
  
  <p>and I want to get the value of another (<code>instB</code>) instance's text <code>(strong) NSString *name</code>.</p>
  
  <pre><code>instA.text = instB.name.
  </code></pre>
  
  <p>If <code>instB</code>'s reference count goes to zero, will <code>instA.text</code> be <code>nil</code>-ed? And can <code>instB</code> even be released because one of it's members's reference count isn't zero yet?</p>
