iOS Facebook和谷歌同时登录？

我正在尝试在同一个应用中实施谷歌+和Facebook登录.我按照Parse和Google的指示,首先成功实现了Facebook登录.然后我开始按照谷歌的说明.完成后,现在我在AppDelegate.swift文件中有这两个函数:

对于谷歌:

func application(application: UIApplication,
    openURL url: NSURL, options options: [String: AnyObject]) -> Bool {
        return GIDSignIn.sharedInstance().handleURL(url,
            sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey],
            annotation: options[UIApplicationOpenURLOptionsAnnotationKey])
}

对于Facebook:

func application(application: UIApplication,
    openURL url: NSURL,
    sourceApplication: String?,
    annotation: AnyObject?) -> Bool {
        return FBSDKApplicationDelegate.sharedInstance().application(application,
            openURL: url,
            sourceApplication: sourceApplication,
            annotation: annotation)
}

我是否需要将这两个代码块合并为1,如某些帖子中所示

Google SignIn SFSafariViewController/WebView在接受权限后重定向到Google.com

或者他们可以在2个不同的街区保持这样的状态？谢谢

你需要结合它们.最简单的方法是使用|| 在退货声明中.试试这个:

func application(application: UIApplication,
    openURL url: NSURL, options: [String: AnyObject]) -> Bool {

        return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as! String, annotation: nil)  ||
            GIDSignIn.sharedInstance().handleURL(url,
            sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as? String,
            annotation: options[UIApplicationOpenURLOptionsAnnotationKey] as? String)
}
