title: Set Text for Custom UIBarButtonItem
body: <p>I need to set title for Custom UIBarButtonItem.</p>
  
  <p>I've the following code:</p>
  
  <pre><code>UIButton* backToRecent = [UIButton buttonWithType:UIButtonTypeCustom];
  [backToRecent setImage:[UIImage imageNamed:@"back.png"]forState:UIControlStateNormal];
  
  [backToRecent addTarget:self action:@selector(backToRecent) forControlEvents:UIControlEventTouchUpInside];
  [backToRecent setFrame:CGRectMake(0, 0, 60, 30)];
  
  UIBarButtonItem* backButtonItem = [[UIBarButtonItem alloc]initWithCustomView:backToRecent];
  [backButtonItem setTitle:@"Recent"];
  partViewController.navigationItem.leftBarButtonItem = backButtonItem;
  [backButtonItem release];
  </code></pre>
  
  <p>But the button appears without the "Recent" text.</p>
