title: How to convert NSNumber to NSString
body: <p>So I have an <code>NSArray</code> "myArray" with <code>NSNumber</code>s and <code>NSString</code>s. I need them in another <code>UIView</code> so i go like this:</p>
  
  <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
  
  DetailViewController *details = [[DetailViewController alloc] initWithNibName:@"DetailView" bundle:nil];
  details.subjectText = [[myArray objectAtIndex:indexPath.row] objectForKey:@"subject"];
  </code></pre>
  
  <p>The subjectText works.
  But how can I get the <code>NSNumber</code>s out of it? (I actually need them as strings...)
  I would convert a <code>NSString</code> out of a <code>NSNumber</code> like this:
  <code>NSString *blah = [NSNumber intValue]</code>. But I don't know how to set it up in the code above...</p>
