<span style="font-family: Arial, Helvetica, sans-serif;">在程式啟動時設定根控制器為 tabbar,如下</span>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    self.window = [[UIWindowalloc] initWithFrame:[[UIScreenmainScreen] bounds]];

    [selfinitTabBar];

    self.window.rootViewController =self.tabBar;

    self.window.backgroundColor = [UIColorwhiteColor];

    [self.windowmakeKeyAndVisible];

    return YES;

}
