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。

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。。
