            if ([model.responseDic[@"error_code"] intValue] == 0) {
                
                
                _dataSource = model.responseDic[@"restaurantList"];
                
                [_tableView reloadData];

}

• 有参数 有URL
• 参数是
  //cityId:城市ID
  //lat:纬度
  //lng:经度
  //showType
  //sendPrice
  //defaultOeder
• 打印model.responseDic为

dishesList =     (
                {
            classificationId = 10001;
            classificationName = "进口食品";
            dishName = "蒙牛纯牛奶1L";
            dishesState = 0;
            id = 1011611107;
            isPackages = 0;
            measureUnit = 9;
            name = "蒙牛纯牛奶1L";
            practiceSortId = 0;
            price = 8;
            recommendFlag = 0;
            smallImgPath = "http://dalianmohekeji.eicp.net:8102/repastmanage/upload/2015/08/19/16/50/20/small1916502378468.jpg";
            tasteSortId = 0;
            total = 0;
            vipPrice = 8;
  };
}

• URL 是利用拼接的方法，一个宏拼接另一个宏。
• 把所有的数据放到字典里
• dic = model.responseDic[@"UserInfo"];
• 在页面中显示就取dic里面的值

 _TextFieldOne.text = _dic[@"clUserName"];
 _TextFieldTwo.text = _dic[@"telephone"];
 _TextFieldThree.text = _dic[@"address"];
