id="more"></a><p>前几天在swift项目中集成了Lua模块，使得在swift工程中用Lua写游戏逻辑成为了可能，具体工程及配置见<a href="https://github.com/usiege/CocosLua" target="_blank" rel="noopener">手把手教你swift项目添加cocos2dx-lua</a>，由于公司最近要把js做的小游戏集成到iOS原生应用中，于是我们将解锁另外一个场景，好了，下面开始；</p><h2 id="同样的，首先你得有一个swift项目"><a href="#同样的，首先你得有一个swift项目" class="headerlink" title="同样的，首先你得有一个swift项目"></a>同样的，首先你得有一个swift项目</h2><p>我们从头开始，建立一个swift项目；我们默认你已经可以自己创建一个全新的swift项目了，这很简单，不是么？<br><img

title="CocosCreator方法集成"></a>CocosCreator方法集成</h3><p>我们最终需要的是如图下的这种目录结构，如果你已经知道这些东西是怎么弄出来的，那么，请跳过本段：<br><img

alt="构建发布"></p><p>发布平台选择iOS，选择一个本地发布路径；模板选择deafault，这个模式下会生成需要的cocos2dx文件夹，我们需要这个库文件夹；暂时不要勾选加密，加密的没有经过实践；</p><p><img

class="headerlink" title="命令行方式集成"></a>命令行方式集成</h3><p>这种方式类似于Lua集成方式，具体请参照<a href="https://github.com/usiege/CocosLua" target="_blank" rel="noopener">手把手教你swift项目添加cocos2dx-lua</a>中的<strong>创建一个cocos2dx-lua项目</strong>部分，只需要将命令行中的语言改为js就可以了：<br><figure class="highlight stylus"><table><tr><td class="gutter"><pre><span

alt="拷贝Classes"></p></li><li><p>Resources<br>swift项目下建立<code>Resources</code>文件夹，将js项目资源拷贝到该目录下，如图：<br><img

alt="不要问我那些蓝色文件与黄色文件的区别"><br>添加依赖工程，打开swift项目，找到我们上面拷贝的cocos2d-x，在<code>cocos2d-x/build</code>下找到<code>cocos2d_libs.xcodeproj</code>，拖到工程中；<br><img src="http://static.zybuluo.com/usiege/dyf807hcs0z74z34y60wp9cr/image_1cf9igoo21m72vai10771bts3hu4u.png" alt="cocos2d_libs.xcodeproj"><br>在<code>cocos2d-x/cocos/scripting/js-bindings/proj.ios_mac/</code>下找到<code>cocos2d_js_bindings.xcodeproj</code>拖到工程中；<br><img

patient!"><br>在添加路径的过程中你需要非常的耐心，因为有可能由于cocos2dx不同的版本会出现需要不同的文件的情况，所以，请仔细查找添加到里面就可以了；</p></li><li><p>build成功，我需要一张图来庆祝一下！！！<br><img src="http://static.zybuluo.com/usiege/8aput74ae6gwq7axtqmsrjto/image_1cf9sqhc1v0k7fr1r3a1o1obs7aj.png" alt="Congratulations!"></p></li></ol><h2 id="我们来写点代码跑我们的JS"><a href="#我们来写点代码跑我们的JS" class="headerlink" title="我们来写点代码跑我们的JS"></a>我们来写点代码跑我们的JS</h2><p>首先我们需要一个桥接文件把C++的初始化操作完成；这里我们需要用OC的桥接类来完成这个任务，我自己创建了一个叫做<code>CocosBridge</code>的类，成生后我们<strong>把.m改为.mm</strong>，这个过程会自动生成一个桥接文件，如果没有自动生成，那么你需要再添加一个<code>CocosJS-Bridge-Header.h</code>的头文件，并把该文件的路径设置到<code>build settings</code>，如下：<br><img src="http://static.zybuluo.com/usiege/u0ks9mrt4znuz1me2weo0413/image_1cf9t8m9c170liqf873i228b8b0.png" alt="CocosBridge"><br><img

alt="swift->objective-c->c++->lua"><br>首先swift与objective-c的互相调用非常方便，其次oc只需要将.m文件写成.mm就可以在实现中直接调用c++方法，并且c++可以直接绑定lua，这样一来，就实现了，ios系语言写主框架，lua写游戏逻辑，直接通过<code>ViewController</code>展现就可以了；并且lua脚本可以像资源添加的方式直接在文件夹中替换，非常方便；基于以上思路，说干就干；</p><h2

alt="image_1cf2ni2nnkpq1pmrsbd1iippri55.png-160.2kB"><br>这里说一点，如果工程是用git管理，因为cocos2d-x下文件比较多，而且是cocos2dx代码文件，所以不必要上传，可添加.gitignore文件：<br><img

title="总结几点性质"></a>总结几点性质</h2><blockquote><ol><li>UIView继承自<code>UIResponder</code>，用于交互，那么这么看来师承自事件流，属于动作学派；</li><li>UIView有一个<code>CALayer</code>的属性，且CALayer继承自<code>NSObject</code>，并且根据苹果文档描述”The base layer class”，看来应该是一个layer体系，且layer用于渲染，属于CA阵营，属于图像学派；</li><li>layer的代理是view，这样看来真正用于显示的应该是CALayer，鬼知道CALayer是不是跟OpenGL有关系；</li><li>所以如果你要是想做动画，那我给你的建议就是，最好在layer层上做；</li><li>对于，你知道layer是有个叫做<code>anchorPoint</code>属性的，做过cocos2dx的应该知道，你说layer的display里难道没有点opengl的痕迹？</li><li>还记得仿射变换吗，平移+线性变换，layer完全是可以做到的；</li><li>layer自身是有绘制能力的，只不过不支持事件响应，但有一点它可以做的到：layer遵从了一个<code>CAMediaTiming</code>的协议，而这个协议就厉害了，配合<code>CACurrentMediaTime</code>，跟系统时钟挂上勾，CPU的时钟周期<code>mach_absolute_time</code>转化成秒数的结果，是一个绝对时间；</li></ol></blockquote><h2

和-setToValue 来指定一个开始值和结束值，这有点像一个补间动画，输入了起始帧和结束帧，其它马由动画帮你；<blockquote><p><img src="http://static.zybuluo.com/usiege/cy71tbwdl9q3ckokbr8hbqhb/image_1ce1gopv01m4lbd41tjr1nel6e39.png" alt="image_1ce1gopv01m4lbd41tjr1nel6e39.png-165.6kB"></p></blockquote></li><li>我们可以指定CALayer的某个属性名为keyPath，并且对CALayer的这个属性的值进行修改，达到相应的动画效果，随着动画的进行，在长度为duration的持续时间内，keyPath相应属性的值从fromValue渐渐地变为toValue，keyPath内容是CALayer的可动画Animatable属性，关于这个可动画属性，我觉得我还可以去谷歌一车，回头再说吧；</li><li>如果<code>fillMode == kCAFillModeForwards</code>同时<code>removedOnComletion == false</code>，那么在动画执行完毕后，图层会保持显示动画执行后的状态。但在实质上，图层的属性值还是动画执行前的初始值，并没有真正被改变；</li></ol><h2 id="它开始动了"><a href="#它开始动了" class="headerlink"

<content type="html"><![CDATA[<p>我想你一定是在开玩笑。<br>源码怎么看，打开看呗！说这话的时候请收下我的轻蔑，哈哈。不过就这个问题我今天在知乎搜索了一通。不要问我为什么在知乎搜索，鬼知道知乎什么都有。<br>那么，请收下我的提问：<br><a id="more"></a></p><blockquote><p><a href="https://www.zhihu.com/question/38215419" target="_blank" rel="noopener">如何阅读Swift源码</a></p></blockquote><p>知乎果然没有让我失望，结果教程如下；</p><blockquote><p><a href="http://swift.gg/2016/12/30/how-to-read-the-swift-standard-libray-source/" target="_blank" rel="noopener"># <a href="http://swift.gg/2016/12/30/how-to-read-the-swift-standard-libray-source/" title="如何阅读 Swift 标准库中的源码" target="_blank" rel="noopener">如何阅读 Swift 标准库中的源码</a></a></p></blockquote><p>顺便提一下，这次搜索还让我发现了一个比较不错的swift网站，有心的同学请收下：<a href="http://swift.gg" target="_blank" rel="noopener">swift.gg</a></p><p>于是今天搞了下源码的编译，并了解到一个叫做 <em>GYB</em> 的东西，这个东西今天先放一下。源碼編譯的過程無非就是用 <em>brew</em> 下了一些命令行軟件，然後使用 <em>build</em> 腳本跑一下過程，在此也不多說。但是今天的重點當然是我們要從源碼出發搞一些事情。<br>续：今天又build，发现也并没有得出什么重要的东西，只是把gyb文件生成为swift文件，其他过程不知道它经历了什么，对我想看源码没有任何作用，还跑了整整一个下午；对于只是想看代码的同学，还是用官网给出的gyb.py脚本做处理吧；</p><ol><li>hashable</li></ol><p>前两天写Dictionary时发现想用枚举做key，自定义一个Dictionary，value是#selector，但是在写的过程中发现说key值需要遵循hashable协议。可以看源码来理解一下。<br>首先要找到Hashable文件，发现swift的标准核心库被放在 <strong>stdlib/public/core</strong> 下，有一个 <strong>Hashable.swift</strong> 文件，打开文件先是一大段的描述，大体内容就是hashable协议作用的场景，以及给出了一个小例子；</p><p>一个Hash类型，提供了一个 hashValue 的属性，它是一个整型常量， 如果有两个相同类型的a，b，如果 a == b，那么 a.hashValue == b.hashValue；但是反过来，如果两个hash值相同，并不表示a 就一定等于 b；<br>还有一点非常重要，就是在两次不同的程序执行中hash值并不保证相等，所以不要把hash值用在你的程序中；<br>Hashable协议可用于struct, enum, class，它继承于 Equatable，所以遵循Hashable协议需要同时实现Hashable协议方法，以及 Equatable 协议方法；</p><figure class="highlight swift"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span

Swift 中，指针都使用一个特殊的类型来表示，那就是 UnsafePointer<t>。遵循了 Cocoa 的一贯不可变原则，UnsafePointer<t> 也是不可变的。当然对应地，它还有一个可变变体，UnsafeMutablePointer<t>。绝大部分时间里，C 中的指针都会被以这两种类型引入到 Swift 中：C 中 const 修饰的指针对应 UnsafePointer (最常见的应该就是 C 字符串的 const char * 了)，而其他可变的指针则对应 UnsafeMutablePointer。除此之外，Swift 中存在表示一组连续数据指针的 UnsafeBufferPointer<t>，表示非完整结构的不透明指针 COpaquePointer 等等。另外你可能已经注意到了，能够确定指向内容的指针类型都是泛型的 struct，我们可以通过这个泛型来对指针指向的类型进行约束以提供一定安全性。</t></t></t></t></p></blockquote><p>需要具体了解的看这篇：<a href="https://onevcat.com/2015/01/swift-pointer/" target="_blank"

alt="image_1c0r0eai5f09qj47rs134c1upu2a.png-145.6kB"></p><p>如上，能保证构建可以成功在Archive过程完成，如遇其他问题，欢迎评论区讨论；<br>之后会再继续完成打包ipa以及上传平台，同时之前提过的SSH部分会持续跟近，因为SSH与本文所讨论的内容并不十分吻合，所以这里不作讨论。</p>]]></content>

：</h2><p>开启Jenkins服务：确认jenkins已安装，在终端进入到jenkins安装目录下，会有一个叫做jenkins.war的文件，<br><figure class="highlight mipsasm"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">$ <span class="keyword">java </span>-<span class="keyword">jar </span><span

alt="image_1c0ptnl2j13mh1mn2hmk18qf7usp.png-188.1kB"></p><p>服务已经就位，可以开始进行配置了；</p><p>这里还有两个命令用于jenkins开启和停用（Mac上）：<br><figure class="highlight stylus"><table><tr><td class="gutter"><pre><span

jenkins.service</span></span><br></pre></td></tr></table></figure></p><p>不过实际操作过程中，可能会出现停用失败的情况，我的做法是直接打开活动监视器，在里面搜java服务，强制关闭掉；这里需要注意，如果服务没有停止再进行jenkins开启是不成功的，提示会告诉你已经在用：</p><p><img

target="_blank" rel="noopener">localhost:8080</a>进行页面化配置了；<br>安装完成之后，Safari可能会自动打开，如果没有自动打开，打开浏览器，输入<a href="http://localhost:8080" target="_blank" rel="noopener">http://localhost:8080</a><br><img

alt="image_1c0pvjgjqfbg3i01c371uhc1ves2j.png-27.6kB"></p><p>这个时候可能会报一个错误。如果出现了这面的问题。出现这个问题的原因就是Java环境有问题，重启Java环境即可。</p><p>这个时候如果你重启电脑会发现Jenkins给你新增了一个用户，名字就叫Jenkins，不过这个时候你不知道密码。你可能会去试密码，肯定是是不对的，因为初始密码很复杂。这个时候正确做法是打开<a href="http://localhost:8080" target="_blank" rel="noopener">http://localhost:8080</a> 会出现下图的重设初始密码的界面。</p><p><img

alt="image_1c0qekdqp9v712rd1gefjdr1fdcbe.png-62.2kB"></p><p>这里我们把login.keychain-db上传到Jenkins里，但是Upload并不能上传这样后缀的文件，所以需要你手动把login.keychain-db修改成login.keychain（复制后再修改，以防止其他地方会引用到带-db）；上传完成后就会在下面出现你一些信息；然后打开你的钥匙串，这个知道在什么地方吧；</p><p><img

connection选项，因为我自己的工程是用gitlab管理的代码，所以需要在Jenkins里下一个Gitlab的插件，然后在里面进行帐号配置，可以采用帐号密码以及SSH的方式，具体这个部分会有一个SSH的坑，先不作分析，后面会讲到，我这里先用帐号密码的方式进行构建，经检验发现SSH方式非必要；</li></ul><p><strong>Credentials</strong>在这里配置：<br><img
