Ios 在目标c的自定义UITable视图中从服务获取数据

.我是IOS新手。我正在制作一个应用程序，希望在

UITableView

我看过很多博客和帖子，都是关于以自定义方式获取数据的，但我没有得到答案。我想在

UIImageView

中显示一个图像，并在label from service中显示一些标签值。我使用内置服务获取数据。

---

有许多post与自定义服务器上的静态数据加载相关。有谁能指导我如何从服务加载自定义样式UItable视图中的数据吗？

为此，您需要同时遵循和教程

一个演示如何自定义

UITableViewCell

，另一个演示如何使用从服务器获取的数据填充

UITableView

。你必须分步做

首先，设计自定义的

UITableViewCell

然后，按照Mike的教程学习如何从API调用设置单元格上的数据

您将使用

NSURLSession

进行API调用。 下面学习如何进行API调用

我们只能在代码量很少的情况下帮助您进行调试。但无法发布完整功能的代码

更新你的问题到目前为止，你已经尝试使你的观点清楚。我已经跟随了一个博客，但我不明白我如何可以这样做的自定义风格@SushilSharmaSo，基本上您希望从服务器获取数据并将数据填充到tableView中。是吗？我建议您遵循许多可用教程中的一个，即，这一个是的，但具有自定义样式，具有名称标签、价格标签、位置标签和图像视图中的图像@我用的是故事板而不是笔尖，你能为故事板编辑它吗？我无法测试@USER3182143我只在故事板中使用了上面的代码，请检查。对不起，好的，让我试试@USER3182143我使用uiview控制器而不是nib，我在其中使用uitableview@USER3182143使用.h、.m、.xib创建单独的cstom UItable视图单元格。
