Swift:如何实现登录情节提要? [英] Swift: How to implement a login storyboard?

问题描述

我有两个不同的故事板:

I have two different storyboards:

• 主板:SWrevealViewController(应用程序的主要部分)
• Loginstoryboard:登录/注册控制器

当用户未登录或注销时，应使用Loginstoryboard.然后应该在Mainstoryboard上进行搜索.

The Loginstoryboard should be used when the user is not logged in or the user logged out. Then there should be a segue to the Mainstoryboard.

如何迅速实施?

期待您的回答！

推荐答案

您是否尝试过在application(_:didFinishLaunchingWithOptions:)

假设Mainstoryboard有您的rootViewController:

if userIsNotLoggedIn {
    let storyboard = UIStoryboard(name: "Loginstoryboard", bundle: nil)
    let loginController = storyboard.instantiateViewControllerWithIdentifier("LoginNavigationController") as UINavigationController
    window?.rootViewController = loginController
}

要在登录后切换视图控制器，您可以执行以下操作:

To switch view controllers once logged in you can do this:

func loggedIn() {
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let mainController = storyboard.instantiateViewControllerWithIdentifier("MainVC") as UIViewController
    let appDelegate = UIApplication.sharedApplication().delegate as AppDelegate
    appDelegate.window?.rootViewController = mainController
}
