Unity3D工程打包成iOS的framework

如果不是公司业务非要用这种方案，请不要选这种方案，坑哭你。。。。 参考链接： unity-in-framework unity-ios-framework

正题

1. 工具版本

unity版本 2018.2.1f Xcode版本 xcode10（10的小版本没一个个试应该都可以 我是10.2.1） 很重要这两个版本对不上 会有很多其他的错误，只能自己在解决了，每个版本unity导出的c文件都不一样，xcode配置也略有不同（具体哪里不同别问我，我也不知道，反正各种报错就对了）。

1. 文件打包

在playsetting中other settings中的strip engine code勾去掉，正常导出unity中的iOS工程。这步不会去百度，很简单，百度也一大堆。

1. 新建iOS的framework工程

新建一个Unity文件夹，文件夹和App..xcodeproj文件同一目录，加入工程 把Data Library Classes都拖进新建的工程 把 Data 文件夹加入工程 选择Create folder refrences

把Library和Classes 加入工程选择Create groups

去掉Library中的libil2cpp文件夹Remove Refreence

把MapFileParser.sh加入到根目录下，不用拖到项目中也就是和App..xcodeproj文件同一目录。

在Build phases中添加Run Script脚本"$PROJECT_DIR/MapFileParser.sh"

加入几个预先写好的类主要是用来调用u3d中界面类的下载地址

重要 SpaceAppController.mm中的sharedController类方法，Unity使用_NSGetExecutablePath来查找可执行文件的路径,所以用facebook的fishhook hook住动态链接。

接下来，我们需要覆盖UnityAppController以防止Unity在加载资源时接管应用程序UI并使用框架路径而不是主程序包。覆盖didFinishLaunchingWithOptions并执行以下更改：

// we will replace this:
//     UnityInitApplicationNoGraphics([[[NSBundle mainBundle] bundlePath] UTF8String]);
// with this:
UnityInitApplicationNoGraphics([[[NSBundle bundleForClass:[self class]] bundlePath] UTF8String]);
复制代码

添加系统库 见下图

 

 

在Build Settings中添加User Define Setting 两项

 

 

继续在Other Lunker Flags中添加-weak_framework CoreMotion -weak-lSystem

Header Search Paths中添加$(PROJECT_DIR)/Unity/Classes $(PROJECT_DIR)/Unity/Classes/Native $(PROJECT_DIR)/Unity/Libraries/bdwgc/include $(PROJECT_DIR)/Unity/Libraries/libil2cpp/include

Other C Flags 添加 -DINIT_SCRIPTING_BACKEND=1 -fno-strict-overflow -DRUNTIME_IL2CPP=1

Prefix Header添加Unity/Classes/Prefix.pch

Mismatched Return Type添加YES 不要用YES(Error)

编译通过

1. 新建测试APP工程

把编译出的framework拖入测试工程

在Build phases中添加Run Script脚本"$PROJECT_DIR/MapFileParser.sh" MapFileParser.sh别忘了拖过来

添加copy file parse

 

 

<figcaption style="display: block; text-align: center; font-size: 1rem; line-height: 1.6; color: rgb(144, 144, 144); margin-top: 2px;"></figcaption>

删掉 Build Setting中的Library Search Paths中的内容

Other C Flags添加$(inherited) -weak_framework CoreMotion -weak-lSystem
