EasySegmentedControl是HMSegmentedControl的swift版本，两个库的实现细节及实现方式是一致的，鉴于里面有很多属性参数的设置，第一次使用此库的人对有的参数使用不是很明白，各参数使用对定制样式实际作用不会很熟悉，故写此文，可以更好的帮助你使用此第三方库，灵活地定制出自己想要的样式。此文提供五种样式Demo，可在此五种样式上灵活调整参数，以定制出不同样式的分段控制器。
接入方式可选择如下方式中的一种：
- pod 'EasySegmentedControl'
- 将EasySegmentedControl.swift文件导入自己的工程

您可根据自己的需要，调整参数达到UI设计的样式规范。
