<span style="font-family: Arial, Helvetica, sans-serif;">在程序启动时设置根控制器为 tabbar,例如以下</span>
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary
*)launchOptions
{
self.window = [[UIWindow
alloc] initWithFrame:[[UIScreen
mainScreen] bounds]];
[self
initTabBar];
self.window.rootViewController =
self.tabBar;
self.window.backgroundColor = [UIColor
whiteColor];
[self.window
makeKeyAndVisible];
return
YES;
