ios - 如何在 ios 中创建以下 json 字符串？

Question

如何在没有 nsmutable 字符串的情况下创建以下格式？

  {
      "appointments" : [
        {
          "pincode" : null,
          "current_status" : "1",

        }
      ],
      "lead_status" : [
        {

        }
      ],
      "lead_followups" : [
        {

        }
      ]
    }

我的代码:

 dicAppointment = [[NSMutableDictionary alloc]init];

    for (int i = 0; i < arrAppointmentData.count; i++)
    {
        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"rowid"] forKey:@"local_id"];
        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"id"] forKey:@"id"];
        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"Fullname"] forKey:@"fullname"];
         [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"email"] forKey:@"email"];

        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"mobileNo"] forKey:@"mobileno"];
        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"date_time"] forKey:@"appt_datetime"];

        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"address"] forKey:@"address"];
        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"cityid"] forKey:@"city_id"];
        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"stateid"] forKey:@"state_id"];
         [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"pincode"] forKey:@"pincode"];
        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"speciality_id"] forKey:@"speciality_id"];


        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"lead_comments"] forKey:@"lead_comments"];
        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"appointment_comment"] forKey:@"appt_comments"];

        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"enquiry_created_date"] forKey:@"enquiry_created_date"];

                  [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"enquiry_created_by"] forKey:@"enquiry_created_by"];

        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"intrested"] forKey:@"interested"];

         [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"lead_follow_by"] forKey:@"lead_followup_by"];

       [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"lead_follow_datetime"] forKey:@"lead_followup_datetime"];

        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"lead_created_date"] forKey:@"lead_created_date"];

         [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"lead_created_by"] forKey:@"lead_created_by"];


         [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"appointment_created_date"] forKey:@"appt_created_date"];

         [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"appointment_created_by"] forKey:@"appt_created_by"];

         [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"initial_status"] forKey:@"initial_status"];

         [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"current_status"] forKey:@"current_status"];

           [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"hospital_id"] forKey:@"hospital_id"];

        [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"cashcredit"] forKey:@"cash_credit"];

         [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"expectdate"] forKey:@"expected_treatment_date"];

           [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"other_hospital"] forKey:@"other_hospital"];

         [dicAppointment setValue:[[arrAppointmentData objectAtIndex:i]valueForKey:@"create_plan_mail_sent"] forKey:@"create_plan_mail_sent"];

    }

三个字典都是一样的:

现在将字典合并到下面的字典上

  NSDictionary *d = @{
                    @"appointments": @[ dicAppointment
                            ],@"lead_followups":@[dicleadStatuss],@"lead_status":@[dicleadStatus]

                    };

以下代码是在json中隐藏:

    NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:d options:NSJSONWritingPrettyPrinted error:&error];
    NSString *jsonString = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding];
    NSLog(@"jsonData as string:\n%@", jsonString);

我已经成功转换了格式，但是...我无法传递多个字典。

谢谢

请帮帮我

Answer 1

在这里，

"appointments" : [ {},{} ]

这是字典数组，因此您需要将 NSDictionary 添加到一个数组，然后需要将该数组转换为 JSON 并将其传递给您的服务器。

 dicAppointment = [[NSMutableDictionary alloc]init];
 arrAppointment = [[NSMutableArray alloc]init];

现在在循环的最后，您需要在 arrAppointment 中添加 dicAppointment

编辑

这里你需要传递你的数组来代替字典

 NSDictionary *d = @{ @"appointments":arrAppointment ,@"lead_followups":arrStatus,@"lead_status":arrLeadStatus };

试试这个
