title: accessing Objective-C nested array element
body: <p>I have an array initialized</p>
  
  <pre><code>- (void) viewDidLoad {
      NSArray *myArray = [NSArray arrayWithObjects:
                     [NSArray arrayWithObjects:@"item 1-1", @"item 1-2", nil],
                     [NSArray arrayWithObjects:@"item 2-1", @"item 2-2", nil],
                     [NSArray arrayWithObjects:@"item 3-1", @"item 3-2", nil],
                     nil];
  }
  
  - (IBAction) someButtonPressed {
      NSString *text = // and here I can't figure out how to actually access the value needed
      [someLabel setText:text];
  }
  </code></pre>
  
  <p>I need to set someLabel text to the "item 1-2" value, for instance. How can I do that? </p>
