  A) Navigation Bar's Layout
     Following is layout of navigation bar which is located under status bar:
     --------------------------------------------------------------------
     |           |                         |         <RightBarButtonItem>       |<br>     --------------------------------------------------------------------<br>  <br>  B) Prepare single view controllers<br>    a) Create a view Nib file for top view controller, suppose this Nib file is named MyTopNib.xib<br>    b) Create files to implement top view controller (it inherits from UIViewController), suppose it is named MyTopViewController<br>    c) Create a view Nib file for sub view controller, suppose this Nib file is named MyFirstSubNib.xib<br>    d) Create files to implement view controller (it inherits from UIViewController also), suppose it is named MyFirstSubViewController,<br><br>  C) Add single view controllers to navigation controller<br>    a) Display Top View<br>      When you want to display top view (such as switch to top view from other view), just add following codes:<br>          MyTopViewController *myTopController = [[[MyTopViewController alloc] initWithNibName:@"MyTopNib.xib" bundle:[NSBundle mainBundle] autorelease];<br>          UINavigationController *navigationController =   [[UINavigationController alloc] initWithRootViewController:myTopController];<br>          [window addSubview:[navigationController view]];<br><br>    b)Enter into Sub-view from Top-view<br>          MyFirstSubViewController *mySecondsController = [[[MyFirstSubViewController alloc] initWithNibName:@"MyFirstSubNib.xi" bundle:[NSBundle mainBundle]] autorelease];<br>          [[self navigationController] pushViewController:mySecondsController animated:YES];<br><br>  D) Customize Navigation Controller<br>    By default:<br>    i) left bar button item, title, and right bar button item are not shown on top navigation view; <br>    ii) title, and back/left/right bar button item are not shown on sub navigation view<br>    But you can customize navigation controller to show these items as following:<br>    a) Set Title of Navigation View<br>      In single view controller (MyTopViewController and MyFirstControllerView), implement function viewDidLoad:, and add codes:<br>          self.title = @"youDefinedTitleForTheView";<br>      to this function<br><br>    b) Add left bar button item to top view<br>        UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithTitle:@"yourDefinedTitleForThisButton" style:UIBarButtonItemStylePlain target:self action:@selector(youDefinedActionForLeftButtonClickEvent:)];<br>        self.navigationItem.leftBarButtonItem = leftButton;  //self is instance of UIViewController, but not UINavigationController<br><br>    c) Add right bar button item<br>        UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"yourDefinedTitleForThisButton" style:UIBarButtonItemStylePlain target:self action:@selector(youDefinedActionForRightButtonClickEvent:)];<br>        self.navigationItem.leftBarButtonItem = rightButton; //self is instance of UIViewController, but not UINavigationController<br><br>    d) Add back bar button item<br>        UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"yourDefinedTitleForThisButton" style:UIBarButtonItemStylePlain target:self action:@selector(youDefinedActionForRightButtonClickEvent:)];<br>        self.navigationItem.backBarButtonItem = backButton; //self is instance of UIViewController, but not UINavigationController<br><br>2, Tab Bar Controller<br>  A) Prepare single view controllers<br>    Do this like that in "Navigation Controller".<br><br>  B) Add single view controllers to navigation controller<br>    a) Create instance of UITabBarController.<br>        UITabBarController *tabBarController = [[UITabBarController alloc] init];<br><br>    b) Create instances of single view controllers and add them to Tab Bar Controller<br>        MyFirstViewController *viewController1 = [[[MyFirstViewController alloc] initWithNibName:@"MyFirstViewNib" bundle:[NSBundle mainBundle] autorelease];<br>        MySecondViewController *viewController2 = [[[MySecondViewController alloc] initWithNibName:@"MySecondViewNib" bundle:[NSBundle mainBundle] autorelease];<br>          <br>        tabBarController.viewControllers = [NSArray arrayWithObjects:viewControllerA, viewControllerB, nil];<br><br>    c) Display<br>        [window addSubView:tabBarController.view];<br><br>  C) Customize Tab Bat Controller<br>    By default, the title and image of Tab Bar items are empty, you can follow steps below to specify theem:<br>    a) Set title<br>      Add following codes in initWithNibName: of your single controller:<br>        self.title = @"youDefinedTitle";<br><br>    b) Set icon<br>      i) Add customized icon<br>      Add following codes in initWithNibName: of your single controller:<br>        self.tabBarItem.image = [UIImage imageNamed:@"youSpecifiedImageFileName"];<br>      Note: The image for tab bar item must contain Alpha channel(Please refer to the original tutorial); Otherwize, the icon will diaplay incorrectly.
