ios - Facebook 登录设置失败

Question

我已多次阅读 Facebook“快速入门”指南，但似乎无法弄清楚是什么导致了此错误。我正在尝试使用以下函数调用通过 FB 进行身份验证:

FBSDKLoginManager().logIn(withReadPermissions: ["public_profile", "email"], from: self) { (result, error) in

}

但是，我收到以下错误控制台输出:

-canOpenURL: failed for URL: "fbauth2:/" - error: "The operation couldn’t be completed. (OSStatus error -10814.)"

这是我的 AppDelegate 方法:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance()!.application(application, didFinishLaunchingWithOptions: launchOptions)
}

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance()!.application(app, open: url, options: options)
}

按照快速入门指南的说明，我已将以下键/值添加到我的 Info.plist 中:

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>fb719997618357318</string>
        </array>
    </dict>
</array>
<key>FacebookAppID</key>
<string>719997618357318</string>
<key>FacebookDisplayName</key>
<string>Test</string>

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fb-messenger-share-api</string>
    <string>fbauth2</string>
    <string>fbshareextension</string>
</array>

需要在AppDelegate中实现该方法

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool{

    return FBSDKApplicationDelegate.sharedInstance().application (
        application,
        open: url as URL!,
        sourceApplication: sourceApplication,
        annotation: annotation)
}

当用户从应用程序登录时将调用此方法。只需尝试一下，让我知道它是否有效，否则我们会尽力帮助您解决其他问题。
