前言

 

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?

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!!!

 

设计

 

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

 

编码

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

xcode6.1 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……

 

PaintCode

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

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

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技术分享

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技术分享

再次选中Oval,同样的方法在拖一个圆出来,

图7技术分享

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技术分享

拖出其中的一个小刻度 

图9技术分享

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

技术分享

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技术分享

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技术分享

 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技术分享

接下来就选中Text工具

图14技术分享

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技术分享

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

图16技术分享

图17技术分享

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……

后记

 

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~
