title: iOS MVC - How to pass data from model to controller?
body: <p>I did quite a bit of research on this, but I am having a mental block about my problem. I am working on Objective-C for an iOS app</p>
  
  <p>Here's my set up:</p>
  
  <ol>
  <li><p>The view controller gets a text from the view (user input), and passes that text to the MethodA of the model.</p></li>
  <li><p>The MethodA in model works on the input text and gets an output (e.g. searches google for that text). It does the search using dispatch_async method which calls the selector to MethodB within model.</p></li>
  <li><p>MethodB parses the output and puts all the results into a NSMutableArray</p></li>
  <li><p><strong>My Question Here:</strong> how do I pass that NSMutableArray back to view controller so I can show it on the view? </p></li>
  </ol>
  
  <p>Sorry, if the answer to my question is very simple/obvious. I am new to Objective-C</p>
