Ios OAuth2:登录后返回应用程序

我正在使用一个名为（）的cocoapod来登录一个带有GitHub的帐户。我只是在玩，因为我想知道OAuth2是如何工作的

以下是迄今为止我在视图控制器（

UIViewController

）中拥有的内容

我想知道的是，在我成功地使用GitHub登录我的帐户后，如何返回到视图控制器。到目前为止，我将被重定向到我在GitHub的开发者网站上注册的URL。我想我需要在

Info

下注册一个回调URL方案。这一切都是全新的。所以我不知道怎么做。谢谢

更新

我通过info.plist添加了一组

URL类型。URL方案已设置为myapp。下面是我在
AppDelegate
中看到的内容

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool {
    if url.scheme == "myapp" && url.host == "oauth" {
        //oauth2.handleRedirectURL(url)
        let storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let controller = storyboard.instantiateViewController(withIdentifier: "HomeView") as! UINavigationController
        let viewController = controller.topViewController as! ViewController
        window?.rootViewController = viewController
    }
    window?.makeKeyAndVisible()
    return true
}

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool {
    if url.scheme == "myapp" && url.host == "oauth" {
        let storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let controller = storyboard.instantiateViewController(withIdentifier: "HomeView") as! UINavigationController
        let viewController = controller.topViewController as! ViewController
        window?.rootViewController = viewController
    }
    window?.makeKeyAndVisible()
    return true
}

但是这个应用程序从来没有调用过上述功能。
我今天学到了一些新东西

在GitHub的开发者网站上，我将回调URL设置为myapp://oauth/callback.  （见下文。）

我通过Info.plist创建了一组URL方案。标识符由我的反向域+唯一名称组成。一个URL项目是myapp。（见下文。）

最后，我在
AppDelegate
中添加了以下代码行

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool {
    if url.scheme == "myapp" && url.host == "oauth" {
        //oauth2.handleRedirectURL(url)
        let storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let controller = storyboard.instantiateViewController(withIdentifier: "HomeView") as! UINavigationController
        let viewController = controller.topViewController as! ViewController
        window?.rootViewController = viewController
    }
    window?.makeKeyAndVisible()
    return true
}

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool {
    if url.scheme == "myapp" && url.host == "oauth" {
        let storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let controller = storyboard.instantiateViewController(withIdentifier: "HomeView") as! UINavigationController
        let viewController = controller.topViewController as! ViewController
        window?.rootViewController = viewController
    }
    window?.makeKeyAndVisible()
    return true
}


如果我登录，我会得到如下提示


当我点击“打开”时，我将被重定向到我的视图控制器。
