In the development project process, we need to use some data on the Internet in many cases. In this case, we may need to write a crawler to crawl the data we need. Generally, regular expressions are used to match Html to obtain the required data.

Animation effects provide a smooth user experience during status or page conversion. In iOS, we do not need to write the animation code by ourselves, core Animation provides a variety of APIs to achieve the Animation effect you need. UIKit only uses
