ios - 实现 iOS 版 Google 登录 (Swift 2.0)

Question

我读过一些关于此的主题，但没有一个主题解决了问题。我正在尝试按照 Google 开发人员 portal 提到的步骤在 iOS 上实现 Google Sign in .

当我在代码中添加 Google 开发者门户中提到的以下 2 个委托(delegate)方法时，我无法编译源代码。

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

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

这是错误屏幕截图:

试试这个

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


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