自己制作了一个日历，是用calendarView写的，可以添加事务。但由于我没写数据库，所以还不能保存事务，只是给大家写了一个模板吧，大家可以连本地数据库，也可以链接云端。(I made a calendar to add transactions. But because I did not write the database, so I can not save the transaction, just write a template for you, you can connect to the local database, you can also link to the cloud.)

说明：  脉冲宽度调制是一种模拟控制方式，根据相应载荷的变化来调制晶体管基极或MOS管栅极的偏置，来实现晶体管或MOS管导通时间的改变，从而实现开关稳压电源输出的改变。这种方式能使电源的输出电压在工作条件变化时保持恒定，是利用微处理器的数字信号对模拟电路进行控制的一种非常有效的技术。脉冲宽度调制是利用微处理器的数字输出来对模拟电路进行控制的一种非常有效的技术，广泛应用在从测量、通信到功率控制与变换的许多领域中。(Pulse width modulation (PWM) is an analog control method, which modulates the bias of transistor base or MOS gate according to the change of load, so as to change the turn-on time of transistor or MOS and realize the change of output of switching regulated power supply. This method can keep the output voltage of the power supply constant when the working conditions change. It is a very effective technology to control the analog circuit by using the digital signal of the microprocessor. Pulse width modulation (PWM) is a very effective technology to control analog circuits by using the digital output of microprocessors. It is widely used in many fields, from measurement, communication to power control and conversion.)
