title: iPhone - People picker, is it possible to change the naviagtion bar color and text?
body: <p>A quick iPhone question, I currently use a people picker in my application, I use a black navigation bar in my application but the people picker displays in the default blue color.</p>
  
  <p>I have tried:</p>
  
  <pre><code>picker.navigationBar.backgroundColor = [UIColor blackColor];
  </code></pre>
  
  <p>However it still displays in the blue color.</p>
  
  <p>Is it possible to change the color of the navigation bar on the people picker? Or is it always going to be blue as it is a system Modal view?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>Using the following works for the color:</p>
  
  <pre><code>picker.navigationBar.tintColor = [UIColor blackColor];
  </code></pre>
  
  <p>However using:</p>
  
  <pre><code>picker.title = @"MyText";
  </code></pre>
  
  <p>or</p>
  
  <pre><code>picker.navigationItem.title=@"MyText";
  </code></pre>
  
  <p>or</p>
  
  <pre><code>self.title=@"MyText";
  </code></pre>
  
  <p>Doesn't work, the title always remains as "All Contacts"</p>
