title: How to create an NSMutableArray and assign a specific object to it?
body: <p>I am just getting into Obj C, and I am looking to create an array of MKAnnotations. </p>
  
  <p>I have already created the MKAnnotation class called <code>TruckLocation</code> that contains the name, description, latitude, and longitude. </p>
  
  <p>Here is what I have so far for the array:</p>
  
  <pre><code>NSMutableArray* trucksArray =[NSMutableArray arrayWithObjects: @[&lt;#objects, ...#&gt;]  nil];
  </code></pre>
