iphone - 在标签栏 Controller /导航 Controller 上方添加自定义 View ？

Question

我尝试了以下代码，试图让自定义 View 显示在选项卡栏 Controller 上方(它的所有选项卡中恰好都有一个导航 Controller )。

问题是它覆盖在导航栏的顶部，我希望导航栏向下移动。

我尝试设置标签栏 Controller 的框架，但这根本没有移动它。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{    
    // Override point for customization after application launch.
    // Add the tab bar controller's current view as a subview of the window
    //self.tabBarController.view.frame = CGRectMake(0, 62, 320, 320);
    self.window.rootViewController = self.tabBarController;

    [self.window makeKeyAndVisible];

    // setting up the header view
    self.headerView = [[HeaderView alloc] initWithFrame:CGRectMake(0, 20, 320, 42)];
    [self.window addSubview:self.headerView];

    // setting up facebook stuff
    AgentSingleton *agentSingleton = [AgentSingleton sharedSingleton];
    agentSingleton.facebook = [[Facebook alloc] initWithAppId:APP_ID];

    return YES;
}

有什么想法吗？

将 View 添加到 tabBarController View 本身:

[self.tabBarController.view addSubview:yourView];
