title: How to change the navigation bar height
body: <p>I saw a solution to change the height of navigation bar. But nothing worked for me. Now my application has one view controller connected with a navigation controller. I have not yet implemented any other code in my project. Before starting my project I need to change my height of my navigation bar.</p>

  </code></pre>
  
  <p>.m:</p>
  
  <pre><code>@implementation UINavigationBar (customNav)
  - (CGSize)sizeThatFits:(CGSize)size {
      CGSize newSize = CGSizeMake(370,40);
      return newSize;
  }
  @end
