title: iOS 7: Custom Back Indicator Image Position
body: <p>I'm having trouble setting properly a custom back indicator image. The indicator is not centered! </p>
  
  <p>Here is a pic:</p>
  
  <p><img src="https://i.stack.imgur.com/28AlJ.png" alt="Screenshot showing non-centered custom back indicator image"></p>
  
  <p>I'm setting the indicator image in <code>didFinishLaunchingWithOptions:</code> method...</p>
  
  <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  
     UIImage *image = [UIImage imageNamed:@"Back"];
     [UINavigationBar appearance].backIndicatorImage = image;
     [UINavigationBar appearance].backIndicatorTransitionMaskImage = image;
  
     return YES;
  }
  </code></pre>
  
  <p>How can I center it? </p>
  
  <p>p.s I've already read this <a href="https://stackoverflow.com/questions/21684661/custom-back-indicator-image-in-ios-7-not-vertically-centered">Custom back indicator image in iOS 7 not vertically centered</a>, but actually it didn't work for me. </p>
