要学习的东西

• MVVM 和干净架构
• 动态单元格高度
• 带模型的 JSON 解码器
• 从服务器预取表数据
• 无限滚动视图
• 在队列中添加新呼叫时取消以前的搜索呼叫。

MVVM 和干净架构

该项目的体系结构使用 MVVM 体系结构。在这里，“ViewController”负责更新 API 并将用户触摸请求传递给 View 模型。

项目狙击 ： –

视图模型是使用 SearchAPIHandler 协议启动的。这里使用了固体原则的开盘原则。任何类都可以使SearchAPI Handler提供一些协议规则。

Dynamic cell height

The tableview cell uses dynamic cell height. The technique to use dynamic cell height is to add constrains from top to bottom and make the table view height dynamic. Other important things is to give don’t give height to labels as it can expand and make its number of lines 0 or custom as per requirement.

JSON Decoder with Models

JSON received from server is mapped to model classes using Codable Protocol and JSONDecoder class.

Prefetch table data from server

When user reaches the bottom of the page, in “prefetchRowsAt” function, we inform view model to fetch more products with “page” incremented.

Infinite scrollview

See the attached GIF. As soon as user reaches bottom of the page, view model fetches data and append to current product list and show.

Canceling Previous Search Call when new call added in Queue.

In the current session, all the tasks are fetched and mached to given search string. If matches and the next request occured, the last all tasks are cancelled.

Projects Snipet : –

When task is cancelled, callback is received with -999 error code. Here return and don’t do anything.
