如何在iOS上调用Rootviewcontroller [英] How to call a Rootviewcontroller on iOS

问题描述

在我的iOS应用程序启动im检查下的用户是注册用户或新用户（如facebook& skype），
比如果用户没有注册，我用我的应用程序代理导航应用程序注册屏幕： / p>

In my iOS application launch im checking wether user is registered user or new user(like facebook & skype), than if user is not register i'm navigating app to register screen with my App delegate:

    if (user != register){

        RegisterViewController *registerViewController = [[RegisterViewController alloc] init];
                RearViewController *rearViewController = [[RearViewController alloc] init];

        UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:registerViewController];

        self.viewController = revealController;

        self.window.rootViewController = self.viewController;

        self.window makeKeyAndVisible];
    }else {

FrontViewController *frontViewController = [[FrontViewController alloc] init];
            RearViewController *rearViewController = [[RearViewController alloc] init];

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:frontViewController];

RevealController *revealController = [[RevealController alloc] initWithFrontViewController:navigationController rearViewController:rearViewController];

self.viewController = revealController;

self.window.rootViewController = self.viewController;

[self.window makeKeyAndVisible];

}

这种方式如果用户没有注册我现在有注册屏幕作为主窗口，

This way if user is not registereds I now have register screen as a main window,

我的问题是：在用户完成注册后，在我的屏幕顶部获取两个导航控制器

My problem is : after user finish registration im im getting two Navigation controller on top of my screen

im使用：

[[self navigationController] pushViewController:revealController animated:YES];

以将应用程序导航到我的主viewController，因为用户现在已注册，

to navigate application to my main viewController since user is now registered,

如何解决这个问题，是否有其他方法修复注册用户问题

how to fix this and is there any other way to fix register user issue

推荐答案

另一个根视图控制器，为什么不设置它而不是推送到另一个navController堆栈：

As you need another root view controller, why not to set it instead of pushing to another navController stack:

[[UIApplication sharedApplication] keyWindow].rootViewController = revealController;
