界面佈局TabBar的應用

要實現的佈局效果是每個TabBar對應的視圖是帶導航欄的TableView視圖.

層次結構是：在一個MainTabBarViewController上加載TabBarItem，而每個TabBarItem對應的視圖是NavigationController視圖，NavigationController指定的根視圖是TableViewController.

代碼如下：

- (void)enterMainView {
    LBQNewNoteViewController *newNoteViewController = [[LBQNewNoteViewController alloc]initWithNibName:@"LBQNewNoteViewController" bundle:nil];
    UITabBarItem *newNoteTabBarItem = [[UITabBarItem alloc]initWithTitle:@"新建筆記" image:[UIImage imageNamed:@"login.png"] tag:0];
    UINavigationController *newNoteNavigation = [[UINavigationController alloc]initWithRootViewController:newNoteViewController];
    newNoteViewController.tabBarItem = newNoteTabBarItem;
    [newNoteTabBarItem release];
    
    LBQCharacterTableViewController *characterTableView = [[LBQCharacterTableViewController alloc]initWithNibName:@"LBQCharacterTableViewController" bundle:nil];
    UITabBarItem *characterTabBarItem = [[UITabBarItem alloc]initWithTitle:@" 文字筆記" image:[UIImage imageNamed:@"CharacterLetter.png"] tag:1];
    //characterTableView.tabBarItem = characterTabBarItem;
     UINavigationController *characterNavigation = [[UINavigationController alloc]initWithRootViewController:characterTableView];
    characterNavigation.tabBarItem = characterTabBarItem;
    [characterTabBarItem release];
    
    LBQPhotoTableViewController *photoTableView = [[LBQPhotoTableViewController alloc]initWithNibName:@"LBQPhotoTableViewController" bundle:nil];
    UITabBarItem *photoTabBarItem = [[UITabBarItem alloc]initWithTitle:@"相冊筆記" image:[UIImage imageNamed:@"Album.png"] tag:2];
    //photoTableView.tabBarItem = photoTabBarItem;
    UINavigationController *ablumNavigation = [[UINavigationController alloc]initWithRootViewController:photoTableView];
    ablumNavigation.tabBarItem = photoTabBarItem;
    [photoTabBarItem release];
    
    LBQAllNoteTableViewController *allNoteTableViewController = [[LBQAllNoteTableViewController alloc]initWithNibName:@"LBQAllNoteTableViewController" bundle:nil];
    UITabBarItem *allNoteTabBarItem = [[UITabBarItem alloc]initWithTitle:@"全部筆記" image:[UIImage imageNamed:@"login.png"] tag:3];
    UINavigationController *allNoteNavigation = [[UINavigationController alloc]initWithRootViewController:allNoteTableViewController];
    allNoteNavigation.tabBarItem = allNoteTabBarItem;
//  allNoteTableViewController.tabBarItem = allNoteTabBarItem;
    [allNoteTabBarItem release];
    
    NSMutableArray *items = [[NSMutableArray alloc]init];
//  [items addObject:newNoteViewController];
    [items addObject:newNoteNavigation];
    [items addObject:characterNavigation];
    [items addObject:ablumNavigation];
    [items addObject:allNoteNavigation];
    
    LBQMainTabBarController *mainTabBarController = [[LBQMainTabBarController alloc]initWithNibName:@"LBQMainTabBarController" bundle:nil];
    [mainTabBarController setViewControllers:items];
    [self presentViewController:mainTabBarController animated:YES completion:nil];
    
}
