自从人生第一篇博客《IOS中的预编译指令的初步探究》问世以来 浏览量竟然达到了360多，（路过的大神勿笑！）这些浏览量使我兴奋异常但又令我黯然神伤，为何我会眼里常含泪水？因为国人伸手党达90%！！！区区只有可怜的三个评论，可怜的三个评论~ 没有鼓励~ 没有鲜花~ 也没有谩骂~ 但是我不哭 因为贱人会笑！我深信：
一日伸手党，bug终身随！
好久没打篮球了，“教练，我想打篮球”。
这次的东西标题为《无比迅速敏捷地开发IOS超精美控件》！就问你怕不怕？？我深恶痛绝标题党丫的，所以今天我就要展示一些奇淫巧技！帅气并且超快的撸出一个IOS精美控件！别说我坑你？
上图1
这个我叫它DDClock，所有view都使用Quartz 2D绘制，创建后自动与当前系统对时同步，漂亮、精致、优雅…… （如果你看到这里，你说不漂亮、不精致、不优雅，那么请你出去，我担心我会下手过重，呵呵），怕了吧，想知道怎么弄得？让博主带你手拿菜刀砍电线，一路火光加闪电！！！
在工程界有一个说法：
设计的优秀与否，是导致这个产品成败的关键。
好吧设计先行！想好了再动手！想好了再动手在生活中是很重要，比如小学生和初中生是怎么区分的？区别就是在LOL中他们对技能的施放是否进行周密的思考，所以一些选手一个人直接冲进人堆里，技能啪啪一甩，然后就挂了——小学生！所以嘛，做事情前养成思考的习惯，是脱离小学生群体的重要手段哦~
前面说到一点，DDClock创建后自动与当前系统对时同步；
1、我们不妨让DDClock继承UIView，然后重载
-(void)drawRect:(CGRect)rect
方法，在这个方法中帅气的画出那个时钟所有细节！坚决不使用人民的一张图片！；
2、然后分析整个DDClock只有指针（时分秒针）和指示上下午的AM、PM会动！所以我们要把这些个东西射成变量！
3、我们还要支持主题的切换，那就给DDClock定义一个枚举咯；
4、然后就这样
5、然后就这样这样
……
哈~ 在我们精细的设计中，这个DDClock的产品形态竟然出乎的饱满，俗话说的好，打铁要趁热，豆腐趁热吃。我们马上祭出杀器XCode！！我知道你现在已经兴奋了
我们就新建一个项目 叫做DDClockDemo吧，用来测试待会我们设计的DDClock。
然后我们就新建一个Group（文件夹）吧 ，就命名成DDClock嘛~
再然后嘛，我们就在DDClock的文件夹下新建一个OC对象吧（Cocoa Touch Class）取名字DDClock，让它继承UIView
Nice！！来看看我们的工程目录结构 图2
我们就开始写代码咯

@endxcode6.1 SDK8.1测试没问题！
代码中已经有无比详细的注释，而且该控件简单地令人发指~ 我相信你看的懂得！
我想肯定有同学已经排着队，准备好了板砖，鸡蛋什么的，“博主！你妹！说好的无比迅速敏捷地开发IOS超精美控件 哪里迅速哪里敏捷？说好的奇淫巧技呢？”
都说心急吃不了热豆腐，我有说文章结束了么？文章只是出轨而已了……
代码是写出来了， 但是在
-(void)drawRect:(CGRect)rect
方法中一笔一笔的勾画出来，确实是累人~
所以我要祭出这次文章的纯24K真大杀器——PaintCode
图3
为何要称PaintCode为终极大杀器？因为它真的很凶！如果说我们刚刚的项目需要花2~3个小时才能完成 而有了PaintCode之后我们只需要10~20分钟！！！就问你怕不怕！！！
售价$99的PaintCode用起来就是爽！
我突然想起自己的一个故事，有一年上大学，父亲到车站来送我，临上车前，父亲叮嘱我等他一会儿他要过铁道对面要给我买点东西，说我一个人过日子会很艰难，我看见他戴着黑布小帽，穿着黑布大马褂，深青布棉袍，蹒跚地走到铁道边，慢慢探身下去，尚不大难。可是他穿过铁道，要爬上那边月台，就不容易了。他用两手攀着上面，两脚再向上缩；他肥胖的身子向左微倾，显出努力的样子。这时我看见他的背影，我的泪很快地流下来了。我赶紧拭干了泪。怕他看见，也怕别人看见。我再向外看时，他已抱了一个黑塑料袋子往回走了。过铁道时，他先将塑料袋散放在地上，自己慢慢爬下，再抱起塑料袋走。到这边时，我赶紧去搀他。他和我走到车上，将塑料袋一股脑儿放在我的皮大衣上：“最新的全是外国的动作片、游戏、音乐光盘，好好照顾自己”，想起老父亲微薄的退休金，我就有点气愤：“爸，你怎么……”，父亲赶忙凑到我的耳边：“D版的，八国联军当年抢得钱是该要回来的”，我：“……”
好了我的故事讲完了 你们可以去找找PaintCode了额
我么开始PaintCode之旅吧
打开Paint
图4
就像PS一样只要你画的出，就能生成代码（支持swift哦）
我们就试试画出DDClock来吧
选中Oval
图5
按住shift键拖出一个规则的圆形 ，填充颜色，这个就是代码中的rimPath
图6
再次选中Oval，同样的方法在拖一个圆出来，
图7
这个就是代码中的facePath。
在PaintCode中尽量讲所有的图形、颜色都自己取一个名字，比如我把第一个Oval取名字rim，第二个Oval取名字face
这样表盘的边框和中间都出来了额，接下来就是表盘的刻度了
选中rect
图8
拖出其中的一个小刻度
图9
然后选中这个小刻度复制出另一个小刻度，放到第一个刻度的对面
图10
然后按住shift键 同时选中这两个小刻度，点击工具栏的Union
图11
这样两个小刻度就成为了一个对象，这时点击右侧的Transforms，就会出现旋转图形的操作，把旋转中心（图12中绿色的瞄准星）拖到钟表的中心位置
图12
这样设置Rotation的参数就可以围绕整个钟表旋转这个刻度了，所以马上同时复制这个刻度5份，分别操作旋转，让它们分别旋转30、60、90、120、150这样所有的刻度都出来了，然后再一次性的选中所有刻度Union一次，把所有刻度合并成一个图形。
图13
接下来就选中Text工具
图14
选中恰当的字体和大小，画出刻度值和上下午提示的AM/PM
图15
最后是时针、分针和秒针了，做法是雷同的，聪明的你肯定知道该怎么做了，反正就是使用规则图形，通过Union、Intersection、Difference的操作产生不规则的图形

最后看我的项目大体情况；
到了这一步其实就可以直接复制代码走人就OK拉
然后写代码，测试，OK啦，是不是把2、3个小时的事情10分钟完成了？哈哈哈
其实PaintCode的强大远不止于此，里面的Variables的功能，可以将图形中的某个值设置成变量，比如代码中的hourAngle、 minuteAngle 、 secondAngle 等，DDClock目前的大小的是固定的200x200，其实使用Variables添加scale的变量，还可以动态的修改所有图形的大小！当然还有Frame的使用啦……
对于PaintCode博主也只是浅尝而止，更多强大的功能，同学们还是自己挖掘吧。
这里附上官网的地址，PaintCode 里面有视频教程，文档等（视频是油管网的，所以需要FQ，呵呵，你懂的）
这里也附上我写的项目源代码 DDClock（尼玛！github使用代理比直接访问更快，你能忍？）
这个礼拜，完成了毕设的主题和一些细节，大概是设计一套移动客户端和后台服务器安全交互的方案，涉及到各种安全通信，可靠性传输，内容加解密等内容，我会把这个设想写到博客上的；
女朋友回老家了，剩下自己一个人撸啊撸T_T;
天杀的12306买了两天都没买到回家的票，明明买不到票，却还要写着有余票，哎，最后我决定坐头等舱回家了~
