iOS Facebook图形批量请求第一个请求不起作用

Question

我有3个链接请求：1.fbRequest和2.meRequest是相同的。 3. thirdPartyIdRequest meRequest和thirdPartyIdRequest依赖于fbRequest。

运行此命令时，每次fbRequest返回一个空响应字典，而meRequest（这是第二次调用的相同调用）和thirdPartyIdRequest返回有效响应。我不确定为什么会这样。

                NSDictionary *dictionary = @{@"fields": @"id, first_name, middle_name, last_name, email, picture.type(large)"};
                NSDictionary *dictionaryThirdPartyIdRequest = @{};

                FBSDKGraphRequest *fbRequest = [[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:dictionary HTTPMethod:@"GET"];
                FBSDKGraphRequest *meRequest = [[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:dictionary HTTPMethod:@"GET"];
                FBSDKGraphRequest *thirdPartyIdRequest = [[FBSDKGraphRequest alloc]
                                              initWithGraphPath:@"custom_audience_third_party_id"
                                              parameters:dictionaryThirdPartyIdRequest
                                              HTTPMethod:@"GET"];


                FBSDKGraphRequestConnection *connection = [[FBSDKGraphRequestConnection alloc] init];
        //request me
                [connection addRequest:fbRequest
                     completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                         //TODO: process me information
                         NSLog(@"result fbRequest %@",(NSDictionary *)result);
                     } batchEntryName:@"fbRequest"];

        //request addRequest:thirdPartyIdRequest ok                    
                [connection addRequest:thirdPartyIdRequest
                     completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                         //TODO: process like information
                         NSLog(@"result thirdPartyIdRequest %@",(NSDictionary *)result);
                     } batchParameters:@{@"depends_on" : @"fbRequest"}];

        //request me ok
                [connection addRequest:meRequest
                     completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                         //TODO: process like information
                         NSLog(@"result meRequest %@",(NSDictionary *)result);
                     } batchParameters:@{@"depends_on" : @"fbRequest"}];
                [connection start];
