title: Can't add objects to a NSMutableArray
body: <p>So I have the following code:</p>
  
  <pre><code>NSMutableArray *array
  array=[[NSMutableArray alloc] init];
  [array addObject: object1];
  [array addObject: object2];
  NSLog(@"%@",array);
  </code></pre>
  
  <p>When I use the app in my iPod connected to my Mac, NSLog writes just null, I don't get object1 object2. What am I doing wrong?</p>
  
  <p>PS: array is a property in .h <code>@property (nonatomic, retain) NSMutableArray *array;</code></p>
