title: Navigation Bar Title Font Size
body: <p>I need to change the size of the Navigation Bar title text for one view controller in my iPhone app. I'm using iOS5, and tried the following code:</p>
  
  <pre><code>if ([self.tabBarItem respondsToSelector:@selector(setTitleTextAttributes:)]) {
      NSLog(@"*** Support method(iOS 5): setTitleTextAttributes:");
      [self.tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                  [UIFont fontWithName:@"AmericanTypewriter" size:20.0f], UITextAttributeFont,
                                                  [UIColor blackColor], UITextAttributeTextColor,
                                                  [UIColor grayColor], UITextAttributeTextShadowColor,
                                                  [NSValue valueWithUIOffset:UIOffsetMake(0.0f, 1.0f)], UITextAttributeTextShadowOffset,
                                                  nil]];
  }
  </code></pre>
  
  <p>However this only applies to the tabBarItem. </p>
