title: What does "out of scope" mean in Xcode debugger (for iPhone)?
body: <p>I'm loading a detailed view of an article when clicking on a row in a UITableView. When clicked, it loads the object with the data and I pass that object to the next controller being pushed on the stack. However, when I do this:</p>
  
  <pre><code>- (void)showArticle
  {
      [aTitle setText:[[self article] title]];
      [aTitle setBackgroundColor:[UIColor clearColor]];
      [[self view] addSubview:aTitle];
  
      [aCategory setText:[[self article] category]];
      [aCategory setBackgroundColor:[UIColor clearColor]];
      [[self view] addSubview:aCategory];
  
      [aAuthors setText:[[self article] authors]];
      [aAuthors setBackgroundColor:[UIColor clearColor]];
      [[self view] addSubview:aAuthors];
  }
  </code></pre>
  
  <p>The <code>title</code> shows up fine, but the <code>category</code> and <code>authors</code> aren't showing up. When I debug, I'm getting "out of scope" when I look at the values of the category/authors. The <code>article</code> object is being @synthesized and I've checked it and it has the right data.</p>
  
  <p>Any ideas? Does that mean that a method is private or something?</p>
  
  <p>Thanks!</p>
