Unity3D研究院之IOS全自动编辑framework、plist、oc代码

2024-07-10 13:16:12   221人阅读

Unity打IOS时会先生成一个Xcode工程，如果你需要增加一些第三方的framework那么需要手动一条一条的添加，这太烦了。。而且可能你还需要修改Plist文件，甚至还可能要修改unity自动生成的oc代码，每次打包都要修改的话，那太累了。。这篇文章就是全自动打包的第一步。。建议使用XUPorter，我在它的基础上拓展了两个类，一个用来修改plist，一个用来修改unity生成出来的OC代码。文章的最后我会给出代码。。

那么我用一个比较变态的SDK举个例子ShareSDK，它就需要自动添加framework，修改plist，还有要修改oc的代码。第一步打开XUPorter/Mods/share.projmods 文件。

}

 frameworks分成两种，一种是系统自带的framework还有一种是第三方的framework。 “frameworks”节点里面放的是系统自带的frameworks。”files”节点里面放的是第三方做出来的framework。 尤其是第三方的framework如果位置放的不对，就不会被xcode所引用的！切记切记！！

folders:可以把某个文件夹下的所有文件拷贝在xcode工程里面，一般sdk都会附带一些oc的代码文件，最好通过folders把oc的代码拷贝在工程里面。或者你也可以把oc的代码放在plugins下面，同样打包的时候也会拷贝进xcode工程。

unity打完IOS或者Android包以后会自动回调一个静态方法。

    [PostProcessBuild (100)]
    public static void OnPostProcessBuild (BuildTarget target, string pathToBuiltProject)

 自动添加framework的原理其实就是等包打完以后，在这个方法里面进行文件的操作，把需要的framework plist oc 代码拷贝进去，或者修改它们。。

        //在指定代码后面增加一行
        UnityAppController.WriteBelow("UnityCleanup();\n}","- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url\r{\r    return [ShareSDK handleOpenURL:url wxDelegate:nil];\r}");
 
    }
 
    #endif
}

 

在回到ShareSDK上，在接微信平台的时候，它们需要在pList 里面增加URL types选项，这里我通过XCPlist增加一行 或者替换一行。

 ShareSDK在接入微信平台的时候 必须修改Unity生成的UnityAppController.mm 文件，这里我通过 XClass 自动修改UnityAppController.mm生成的代码。 主要是增加代码和替换代码 两部分。。

像这样，我就可以把unity生成的代码修改了。。

最后是工程地址：http://pan.baidu.com/s/1i3gLDTN

建议大家把工程下载下来看看一基本上就明白它的工作原理了。如果你掌握者本篇文章的知识 那么恭喜你 自动化打包就已经完成了一半。。 现在我们已经可以自动化生成 xcode工程了，等有时间的话我会把下一半shell 自动化打包.ipa的方法在整理出来。。
