Unity3D工程打包成iOS的framework

如果不是公司業務非要用這種方案，請不要選這種方案，坑哭你。。。。 參考鏈接： unity-in-framework unity-ios-framework

正題

1. 工具版本

unity版本 2018.2.1f Xcode版本 xcode10（10的小版本沒一個個試應該都可以 我是10.2.1） 很重要這兩個版本對不上 會有很多其他的錯誤，只能自己在解決了，每個版本unity導出的c文件都不一樣，xcode配置也略有不同（具體哪里不同別問我，我也不知道，反正各種報錯就對了）。

1. 文件打包

在playsetting中other settings中的strip engine code勾去掉，正常導出unity中的iOS工程。這步不會去百度，很簡單，百度也一大堆。

1. 新建iOS的framework工程

新建一個Unity文件夾，文件夾和App..xcodeproj文件同一目錄，加入工程 把Data Library Classes都拖進新建的工程 把 Data 文件夾加入工程 選擇Create folder refrences

把Library和Classes 加入工程選擇Create groups

去掉Library中的libil2cpp文件夾Remove Refreence

把MapFileParser.sh加入到根目錄下，不用拖到項目中也就是和App..xcodeproj文件同一目錄。

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

加入幾個預先寫好的類主要是用來調用u3d中界面類的下載地址

重要 SpaceAppController.mm中的sharedController類方法，Unity使用_NSGetExecutablePath來查找可執行文件的路徑,所以用facebook的fishhook hook住動態鏈接。

接下來，我們需要覆蓋UnityAppController以防止Unity在加載資源時接管應用程序UI並使用框架路徑而不是主程序包。覆蓋didFinishLaunchingWithOptions並執行以下更改：

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

添加系統庫 見下圖

 

 

在Build Settings中添加User Define Setting 兩項

 

 

繼續在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)

編譯通過

1. 新建測試APP工程

把編譯出的framework拖入測試工程

在Build phases中添加Run Script腳本"$PROJECT_DIR/MapFileParser.sh" MapFileParser.sh別忘了拖過來

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>

刪掉 Build Setting中的Library Search Paths中的內容

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