Teach you to use Jenkins to continue integrating iOS projects

But just using the controls in the Uikit is not enough, if now the product needs a similar Excel-style control to render the data, you need the control to swipe up and down, you will find that there is no ready-made controls available in Uikit. UITableView can be seen as an Excel that can only scroll up and down, so our intuition is to write UITableView to implement this custom control. This article I will through the open source project Chameleon to analyze the UITableView hacking source code, after reading this article you will understand UITableView's drawing process and uitableviewcell reuse principle. And I'll implement a custom control like Excel in the next article.
