iphone – 将UITabBarController与UINavigationController结合使

在[appName] -Info.plist中删除对主xib的引用

在main.m中,加载您的委托：

int retVal = UIApplicationMain(argc,argv,nil,@"myAppDelegate");

在app delegate中,加载tabBar,导航控制器和navigationController中的视图.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // create window since nib is not.
    CGRect windowBounds = [[UIScreen mainScreen] applicationFrame];
    windowBounds.origin.y = 0.0;
    [self setWindow:[[UIWindow alloc] initWithFrame:windowBounds]];

    // View Controllers for tabController (one viewController per tab)
    NSMutableArray *viewControllers = [[NSMutableArray alloc] init];

    // first tab has view controller in navigation controller
    FirstView *firstView = [[FirstView alloc] initWithNibName:@"FirstView" bundle:nil];
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:firstView];
    [viewControllers addObject:navController];

    SecondView *secondView = [[SecondView alloc] initWithNibName:@"SecondView" bundle:nil];
    [viewControllers addObject:secondView];    

    // create the tab controller and add the view controllers
    UITabBarController *tabController = [[UITabBarController alloc] init];
    [tabController setViewControllers:viewControllers];

    // add tabbar and show
    [[self window] addSubview:[tabController view]];
    [self.window makeKeyAndVisible];
    return YES;
}
