【问题描述】：

我已发送 Facebook 请求。它工作正常，但我只在 iPhone facebook 应用程序中收到请求（通知），而不是在 Facebook 网络应用程序中。我希望 Facebook 本机应用程序和 Web 应用程序都能接收通知。我该怎么做？

#pragma Sending Facebook app request

- (NSDictionary*)parseURLParams:(NSString *)query

        NSString *val =
        [[kv objectAtIndex:1]

        [params setObject:val forKey:[kv objectAtIndex:0]];

【问题讨论】：

欢迎来到***。从现在开始在 SO 中发帖时请考虑以下几点 1) 引用自己时使用“I”，而不是“i”。 2) 看来您的母语不是英语，但请确保正确拆分句子并使用“。”在哪里到期。 3) This is how you format code in SO 4) Please don't use 'Hi', 'Thanks' etc tag lines in your post

@Krishnabhadra 谢谢

只有在您的应用程序实现了 Facebook Canvas 应用程序时，您才能在 Facebook 网络应用程序上收到通知。

invitable_friends API 仅适用于具有 使用 Graph API 2.0 版的 Facebook Canvas 应用实施。
