xcode project.pbxproj文件的介绍

PBXBuildFile与PBXFileReference

PBXBuildFile与PBXFileReference这两个section保存中工程文件相关的信息:包含文件的类型，路径，名称等

<code class="hljs avrasm has-numbering"><span class="hljs-comment">/* Begin PBXBuildFile section */</span>
    <span class="hljs-number">2</span>B82218D1B75AC8800BDEFB7 <span class="hljs-comment">/* Foundation.framework in Frameworks */</span> =

                            fileRef = <span class="hljs-number">2</span>B82218C1B75AC8800BDEFB7

<span class="hljs-comment">/* End PBXFileReference section */</span></code>

PBXGroup

这个section保存着工程文件的分组信息：分组的名称，以及该组内含有的文件，比如下面的例子，一个EGOTableViewPullRefresh分组里面还有一个children子分组，同时该组包含EGORefreshTableHeaderView的.h和.m两个文件，该分组对应的相对路径为../Classes/EGOTableViewPullRefresh

<code class="hljs cs has-numbering">        E1B4A9DE12FC8B1000EB3F67 <span class="hljs-comment">/* EGOTableViewPullRefresh */</span> = {
            isa = PBXGroup;
            children = (
                E1B4A9DF12FC8B1000EB3F67 <span class="hljs-comment">/* EGORefreshTableHeaderView.h */</span>,
                E1B4A9E012FC8B1000EB3F67 <span class="hljs-comment">/* EGORefreshTableHeaderView.m */</span>,
            );
            name = EGOTableViewPullRefresh;
            path = ../Classes/EGOTableViewPullRefresh;
            sourceTree = <span class="hljs-string">"<group>"</span>;
        };
<span class="hljs-comment">/* End PBXGroup section */</span></code>

PBXNativeTarget

该section保存工程创建的target信息：包含target的对应的配置信息、创建规则、依赖、名称和类型等信息

<code class="hljs cs has-numbering"><span class="hljs-comment">/* Begin PBXNativeTarget section */</span>
        <span class="hljs-number">1</span>D6058900D05DD3D006BFB54 <span class="hljs-comment">/* MyBaby */</span> = {
            isa = PBXNativeTarget;
            buildConfigurationList = <span class="hljs-number">1</span>D6058960D05DD3E006BFB54 <span class="hljs-comment">/* Build configuration list for PBXNativeTarget "MyBaby" */</span>;
            buildPhases = (
                <span class="hljs-number">1</span>D60588D0D05DD3D006BFB54 <span class="hljs-comment">/* Resources */</span>,
                <span class="hljs-number">832</span>D4F01120A6F7C001708D4 <span class="hljs-comment">/* CopyFiles */</span>,

                <span class="hljs-number">1</span>D60588F0D05DD3D006BFB54 <span class="hljs-comment">/* Frameworks */</span>,
                <span class="hljs-number">79289</span>B3ECCA2441197B8D7F6 <span class="hljs-comment">/* Copy Pods Resources */</span>,
            );
            buildRules = (
            );
            dependencies = (
            );
            name = MyBaby;
            productName = WordPress;
            productReference = <span class="hljs-number">1</span>D6058910D05DD3D006BFB54 <span class="hljs-comment">/* My Baby.app */</span>;
            productType = <span class="hljs-string">"com.apple.product-type.application"</span>;
        };
<span class="hljs-comment">/* End PBXNativeTarget section */</span></code>

XCBuildConfiguration与XCConfigurationList

这两个section保存着工程相关的配置信息：下面对应的是debug模式下的配置信息，可以看到里面包含CODE_SIGN_IDENTITY，sdk，framework的搜索路径等信息。

<code class="hljs objectivec has-numbering"><span class="hljs-comment">/* Begin XCBuildConfiguration section */</span>
        C01FCF5008A954540054247B <span class="hljs-comment">/* Release */</span> = {

            buildSettings = {

            };
            name = Release;
        };
<span class="hljs-comment">/* End XCBuildConfiguration section */</span>

<span class="hljs-comment">/* Begin XCConfigurationList section */</span>
        C01FCF4E08A954540054247B <span class="hljs-comment">/* Build configuration list for PBXProject "MyBaby" */</span> = {

            defaultConfigurationIsVisible = <span class="hljs-number">0</span>;
            defaultConfigurationName = Release;
        };
<span class="hljs-comment">/* End XCConfigurationList section */</span></code>

通过上面分析一个pbxproj文件的过程可以看出，要创建一个工程，首先需要添加相关的文件，然后设置需要生成的target以及对应的配置信息就行了。
