How to decrease the UINavigation Bar size and how to separate the back button from navigation bar
<p>I am developing one application.In that I need to decrease the UINavigationBar size, For that I use the below code.</p>

<pre><code>CGFloat navBarHeight = 10.0f;    
CGRect frame = CGRectMake(50.0f, 0.0f, 320.0f, navBarHeight);
[self.navigationController.navigationBar setFrame:frame];
</code></pre>

<p>But when I go to next page, that page Navigationbar also changed.But I need to change only one page. And I want to separate the back button and place before navigation bar.So for that i place one button before UINavigationBar.But I don't perform it action. </p>
