通过iOS应用程序读取邮箱或用户节点

Question

为什么此代码在获取收件箱时出错？

FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                              initWithGraphPath:@"/me/inbox"
                              parameters:@{@"fields":@"inbox"}
                              HTTPMethod:@"GET"];

登录控制台时出错：

{
    code = 100;
    message = "You can only access the \"inbox\" connection for the current user.";
}

好像如果我使用此代码来获取收件箱，则会将其提取到收件箱：

FBSDKGraphRequest *request =[[FBSDKGraphRequest alloc] initWithGraphPath:@"me"
                                                          parameters:@{ @"fields" : @"inbox"}];

想出来不能传递param中的字段

FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                              initWithGraphPath:@"/me/inbox?limit=50"
                              parameters:nil    
                              HTTPMethod:@"GET"];
