Answer 1

只需将这 4 行代码添加到注销按钮，即可清除所有 cookie，这样您就可以成功从 facebook 注销。

    NSHttpCookieStorage storage = NSHttpCookieStorage.SharedStorage;

    foreach (NSHttpCookie cookie in storage.Cookies) 
    {
      if(cookie.Domain == ".facebook.com")
      {
        storage.DeleteCookie(cookie);
      }

    }

Apple iOS 6 提供的 Social.framework 不需要您登录或注销。

用户凭据（用于 Facebook）保存在 iOS 设置中（应用程序无法访问），因此操作系统能够按需登录，并在您完成后将您注销。这可能发生在您发布最后一个实例之后SLRequest或之后的某个时间（例如缓存）。
