title: UINavigationBar title
body: <p>I am trying to use a UILabel to replace the title at the UINavigationBar, the code is as follows:</p>
  
  <pre><code>UINavigationBar *bar = [self.navigationController navigationBar];
      [bar setBackgroundColor:[UIColor blackColor]];
  
      UILabel * nav_title = [[UILabel alloc] initWithFrame:CGRectMake(80, 2, 220, 25)];
      nav_title.font = [UIFont fontWithName:@"Arial-BoldMT" size:18];
      nav_title.textColor = [UIColor whiteColor];
      nav_title.adjustsFontSizeToFitWidth = YES;
      nav_title.text = title;
      nav_title.backgroundColor = [UIColor clearColor];
      [bar addSubview:nav_title];
      [nav_title release];
  </code></pre>
  
  <p>The problem is that, how do I remove the original title of the bar? I didn't declare any self.title = @"title", but it always shows it there:</p>
  
  <p><img src="https://i.stack.imgur.com/VGtkx.png" alt="enter image description here"></p>
  
  <p>If I do self.title = nil, then everything is gone... How do eliminate this mysterious title from the navbar and just use the UILabel I created.</p>
