Google和Facebook在AppDelegate中登录url处理程序？

Question

所以我已经集成谷歌登录到我的应用程序，并具有以下功能在我AppDelegate.swift：

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { 
    // handled to go back to application after google log in 
    let handled = GIDSignIn.sharedInstance().handle(url, sourceApplication:options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String, annotation: [:]) 

    return handled 
} 

现在我想要添加Facebook登录和我应该添加以下到相同的功能：

let handled = FBSDKApplicationDelegate.sharedInstance().handle(application(app, open: url, options: [UIApplicationOpenURLOptionsKey.sourceApplication], annotations: options[:]) 

我该如何处理需要返回两个不同的handled变量？

就是这样，我发现来管理这两种情况下

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool { 

    let canHandleURL = FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation) 
    let canHandleGoogleUrl = GIDSignIn.sharedInstance().handleURL(url, sourceApplication: sourceApplication!, annotation: annotation) 
    if canHandleURL { 
     return true 
    } else if canHandleGoogleUrl { 
     return true 
    } else { 
     return false 
    } 
} 

继@JAL建议，可以优化该代码添加以下行：

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool { 

    return FBSDKApplicationDelegate.sharedInstance().application(applic‌​ation, openURL: url, sourceApplication: sourceApplication, annotation: annotation) || GIDSignIn.sharedInstance().handleURL(url, sourceApplication: sourceApplication!, annotation: annotation) 

}
