ios应用开发所有实验：1：实现HelloWord。
具体内容:按课堂讲授的内容，设计一个Helloworld类，在命令行下打印"HelloWorld".要求实现一个类方法，两个实例方法。
并使用属性。
2、利用栈实现数学表达式求值具体内容:利用ObjectC和Foundation框架，利用栈实现数值表达式的求值。
(要求不使用NSExpression)。
2：利用ObjectC和Cocoa框架，利用上次实验实现的表达式求值的类来开发一个四则运算器在模拟器中运行3：在上次实验实现的单场景计算器的基础上，利用导航控制器实现高级计算功能，完成所有的高级计算器

特别注意：1.控制板上的大电解电容耐压要在30V以上！2.控制板有2个电源输入，1个接5V输入，另一个接20V2.5A左右的电源（千万别接特别大功率的电源比如4A5A的，电流电位器调不好时容易烧坏芯片或芯片爆）3.总的24V保险丝一定要焊接好，不能用导线直连4.为了真空吸料能稳定放下料，程序里做了一定的延时，如果要去掉延时加快，可以手动改下代码去掉延时，在publicvoidsmt_single_thread(objectinn)函数里

面向对象的分析（ObjectOrientedAnalysis,OOA），就是运用面向对象方法进行系统分析。
OOA是分析，是软件生命周期的一个阶段，具有一般分析方法共同具有的内容、目标及策略；
但强调运用面向对象方法进行分析，用面向对象的概念和表示法表达分析结果。
基本任务是：运用面向对象方法，对问题域和系统责任进行分析和理解，找出描述问题域及系统责任所需的对象，定义对象的属性、操作以及它们之间的关系。
目标是建立一个符合问题域、满足用户需求的OOA模型

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
