从Objective c中的自定义UITable View中获取服务中的数据

enter image description here .Im new to IOS. I am making an app where I want to get data from there in UITableView.
I have seen many blogs and post related to getting data in custom style, but I don't get my answer. I want to show an image in UIImageView and some labels values in label from service. Im using built in service to get data. There are many post related to static data loading on custom. Can anyone guide how can I load data in my own custom style UItable VIEW FROM SERVICE?

在这里输入图像描述。我是IOS新手。我正在创建一个应用程序，我想从UITableView中获取数据。我见过许多博客和帖子与自定义风格的数据有关，但我没有得到我的答案。我想在UIImageView中显示一个图像，并在服务的标签中显示一些标签值。我使用内置服务来获取数据。在自定义上有许多与静态数据加载相关的帖子。任何人都可以指导如何在我自己的自定义样式UItable VIEW FROM SERVICE中加载数据？

For this you need to follow both Appcoda and mikesknowledgebase tutorials .

为此，您需要遵循Appcoda和mikesknowledgebase教程。

One shows how to customize UITableViewCell and other shows how to populate UITableView with data fetched from server. You will have to do it in steps.
