title: iPhone Title and Subtitle in Navigation Bar
body: <p>In my application, I'd like to have the navigation bar display a title and subtitle.</p>
  
  <p>To that extent, I added the following code to my view controller:</p>
  
  <pre><code>// Replace titleView
  CGRect headerTitleSubtitleFrame = CGRectMake(0, 0, 200, 44);    
  UIView* _headerTitleSubtitleView = [[[UILabel alloc] initWithFrame:headerTitleSubtitleFrame] autorelease];
  _headerTitleSubtitleView.backgroundColor = [UIColor clearColor];
  _headerTitleSubtitleView.autoresizesSubviews = YES;
  
  CGRect titleFrame = CGRectMake(0, 2, 200, 24);  
  UILabel *titleView = [[[UILabel alloc] initWithFrame:titleFrame] autorelease];
  titleView.backgroundColor = [UIColor clearColor];
  titleView.font = [UIFont boldSystemFontOfSize:20];
  titleView.textAlignment = UITextAlignmentCenter;
  titleView.textColor = [UIColor whiteColor];
  titleView.shadowColor = [UIColor darkGrayColor];
  titleView.shadowOffset = CGSizeMake(0, -1);
  titleView.text = @"";
  titleView.adjustsFontSizeToFitWidth = YES;
  [_headerTitleSubtitleView addSubview:titleView];
  
  CGRect subtitleFrame = CGRectMake(0, 24, 200, 44-24);   
  UILabel *subtitleView = [[[UILabel alloc] initWithFrame:subtitleFrame] autorelease];
  subtitleView.backgroundColor = [UIColor clearColor];
  subtitleView.font = [UIFont boldSystemFontOfSize:13];
  subtitleView.textAlignment = UITextAlignmentCenter;
  subtitleView.textColor = [UIColor whiteColor];
  subtitleView.shadowColor = [UIColor darkGrayColor];
  subtitleView.shadowOffset = CGSizeMake(0, -1);
  subtitleView.text = @"";
  subtitleView.adjustsFontSizeToFitWidth = YES;
  [_headerTitleSubtitleView addSubview:subtitleView];
  
  _headerTitleSubtitleView.autoresizingMask = (UIViewAutoresizingFlexibleLeftMargin |
                                        UIViewAutoresizingFlexibleRightMargin |
                                        UIViewAutoresizingFlexibleTopMargin |
                                        UIViewAutoresizingFlexibleBottomMargin);
  
  self.navigationItem.titleView = _headerTitleSubtitleView;
  </code></pre>
  
  <p>And also implemented a method:</p>
  
  <pre><code>-(void) setHeaderTitle:(NSString*)headerTitle andSubtitle:(NSString*)headerSubtitle {
      assert(self.navigationItem.titleView != nil);
      UIView* headerTitleSubtitleView = self.navigationItem.titleView;
      UILabel* titleView = [headerTitleSubtitleView.subviews objectAtIndex:0];
      UILabel* subtitleView = [headerTitleSubtitleView.subviews objectAtIndex:1];
      assert((titleView != nil) &amp;&amp; (subtitleView != nil) &amp;&amp; ([titleView isKindOfClass:[UILabel class]]) &amp;&amp; ([subtitleView isKindOfClass:[UILabel class]]));
      titleView.text = headerTitle;
      subtitleView.text = headerSubtitle;
  }
  </code></pre>
  
  <p>Things work beautifully, thanks.</p>
  
  <p>Except that when rotating the iPhone to Landscape, the title+subtitle don't downsize in an automatic manner like the default title of the navigation item.</p>
  
  <p>Any pointers?</p>
  
  <p>Thanks!</p>
