title: How to move a bar button item within a nav bar
body: <p>I have a custom bar button item that I want to nudge down 5 pixels. How would I go about doing that witht the following code. I tried to set the "y" point but keep getting syntax errors.</p>
  
  <pre><code>     [self.navigationController setNavigationBarHidden:NO animated:YES];
  
       UIImage *image = [UIImage imageNamed:@"arrow_back.png"];
       UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
  
       [self.navigationController.navigationBar addSubview:imageView];
  
      [imageView release];
  
       UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
       [button setImage:buttonImage forState:UIControlStateNormal];
  
       //set the frame of the button to the size of the image (see note below)
       button.frame = CGRectMake(0, 0, buttonImage.size.width, buttonImage.size.height);
  
      [button addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];
  
       //create a UIBarButtonItem with the button as a custom view
       UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];
       self.navigationItem.leftBarButtonItem = customBarItem;
  
      [customBarItem release];
  }
  </code></pre>
  
  <p>thanks for any help</p>
