使用 swift 添加 Facebook 时出现 ParseUI 错误

Question

所以我按照解析网站 (https://www.parse.com/docs/ios_guide#fbusers/iOS) 上的步骤添加 Facebook 登录。但是 Xcode 给了我错误 '() -> FBSDKApplicationDelegate!'我的应用委托文件中的以下代码行没有名为“application”的成员

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

我错过了什么？

Answer 1

您似乎缺少 sharedInstance 的括号。

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