今天是2017年7月7日－星期六
2017/7/5-2017/7/6，我作为一个新人进入到公司任职iOS开发实习生，在今天对这两天的工作进行一下总结:
1.我作为一个新人加入到艺网这个大家庭之中，通过这两天的工作感觉这是一个很和谐的大家庭，并且不论是工作氛围，还是休息时的氛围都很是不错。
2.在这两天之中我做了一个分类的Demo并且学习了一下Masonry这个第三方的使用方法：
2.1 分类Demo
先上一个结果图

－－－－－－－－－－－－－－－－－－－－－－－－－
做的Demo比较low，但不要在意这些细节。
介绍一下文件
SudokuViewAndButton.h //这个View用来放集合视图和按钮
SudokuButtonShadowView.h //这个View用来实现按钮
CustomCollectionView.h //这个View用来实现集合视图
SudokuCollectionCell.h //这个一看就知道是集合视图的item
CollectionHeaderView.h //这个也很易懂的，用来实现集合视图的头视图
简单介绍下各个文件

SudokuViewAndButton与SudokuButtonShadowView
这里就不再拷贝代码，仅仅做一下说明。原因是这两个类中的方法与之前的文件方法相差不多。
先说一下SudokuButtonShadowView这个类的组成，这个类中实现了一个-(void)ButtonShadowViewWithRequst:(SudokuButtonShadowViewBlock)block;方法用于回调点击事件。其次在.m文件中阴影的效果实现是通过在按钮（button）下添加一个View，用这个View做阴影实现的。
SudokuViewAndButton这个类就更简单了，它主要实现的是将SudokuButtonShadowView和集合视图显示出来。
