需求
app开发中经常会有日期选择（如生日、睡眠定时等）或者省市区选择等此类功能，通常ui中不会单独使用ui中的控件，而是在uipickerview的基础上增加一个取消和确定按钮
特点
1、支持常见的选择型的数据格式
该控件集成了 yyyy-mm-dd、yyyy-mm、hh mm、省市级联、省市区级联、自定义数据源（2列）、自定义数据源（3列）等多种格式
2、即支持uitextfield又支持事件触发机制
3、即支持xib也支持纯代码
效果图
github：xxpickerview
集成
首先将xxpickerview文件夹拖入到工程中
纯代码（选择任意一种模式）

xib方式
1、绑定自定义类
2、拖线并设置模式
