今天是周六，趁着还有多余的空闲，把这周的干活拿出来晒一晒。首先看项目的截图。
这个就是项目的截图，很明显这是一个日历，由于有特殊的需求，比如每个日期需要添加点击事件，分别为每天设置不同的考勤信息，类似于这种只能用自定义view去实现。
分析：
1.首先观察日历每一行的背景都是岔开的，这种如何实现。
2.每周六跟周日的日期颜色不一样。
3.特殊日期有圆形图形包起来。
4.星期要跟日期对应起来。
5.需要考虑如果一个月只有28天的话，就不需要绘制那么多行。
技术难点：
1.关于坐标的计算，这个是比较麻烦的，因为涉及到点击事件，还涉及到日期与星期的对应。
2.屏幕适配，坐标的计算以及字体的大小需要根据屏幕的适配进行调整。
3.绘制文字圆形背景的时候，如何保证文字在圆圈的中间。
5.日期切换，数据及逻辑处理等等。
我在拿到项目的需求后，首先我也在网上找了下，也有很多成熟的方案，但是我还是想自己写一些，第一给人的感觉这个应该是不难的，但是实际自己动起手来才发现，事实并不如此。当中的坑是你想不到的。但是只有自己真正的写出来才会进步，我感觉能把这个自己写出来，自定义view方面也都不是什么难事了。
解析思路：
1.为了避免背景被文字覆盖，所以需要先要绘制背景。
2.计算每个月有多少天，每个月的第一天是周几。
3.绘制文字，在绘制文字的同时，需要给文字绘制圆形背景，避免圆形背景覆盖文字。
4.添加点击事件，判断点击的坐标点是在哪个点的范围内。
