由于項目有此需求，所以不得不爬此坑，爬了兩天終于出坑
參考
參考使用的Unity版本是2018.2.1f1 我的是2018.4.0f1 所以配置上有不同
1.首先Unity導出Xcode工程 這里注意一下 strip engine code 去勾
2.生成的iOS工程取MapFileParser.sh、Classes、Data、Libraries四個文件
3.將文件導入framework工程中（iOS創建framework這里不講解） 工程結構如下
Unity和testlibocSDK文件是同一目錄 Data文件的引用選擇Create folder refrences，其他選擇Create groups，然后將Libraries下的libil2cpp文件夾Remove Refreence
Build phases配置
4.在Build phases中添加Run Script腳本"$PROJECT_DIR/MapFileParser.sh"
5.添加幾個類文件 類的下載地址
將SpaceAppController.h設置為Public
Build Settings設置
6.因為原生引用游戲 所以此SDK應該是動態庫 靜態庫的話下面會說導致的問題 而且靜態庫比較占用資源 Mach-O Type 不用修改 （默認就是動態庫 - Dynamic Library）
7.Other Linker Flags 添加$(inherited)、-weak_framework、CoreMotion、-weak-lSystem
8.Header Search Paths 添加
- $(inherited)、
- "$(SRCROOT)"、
- $(PROJECT_DIR)/Unity/Classes、
- $(PROJECT_DIR)/Unity/Classes/Native、
- $(PROJECT_DIR)/Unity/Libraries、
- $(PROJECT_DIR)/Unity/Libraries/bdwgc/include、
-
$(PROJECT_DIR)/Unity/Libraries/libil2cpp/include

9.Library Search Paths 不用設置 自己生成
10.Other C Flags 添加$(inherited)、-DINIT_SCRIPTING_BACKEND=1、-fno-strict-overflow、-DNET_4_0、-DRUNTIME_IL2CPP=1
11.Other C++ Flags
12.Prefix Header 添加Unity/Classes/Prefix.pch
13.Mismatched Return Type添加YES 不要用YES(Error)
14.User-Defined 添加UNITY_RUNTIME_VERSION -> Unity 版本號、UNITY_SCRIPTING_BACKEND -> il2cpp
爬坑過程！！
1.WWWConnection.h:4:41: error: cannot find interface declaration for 'NSObject', superclass of 'UnityWWWConnectionDelegate'
解決：系統庫添加少了
2.'Classes/Unity/UnitySharedDecls.h' file not found
解決：找到文件 刪除前面路徑 改成 #include "UnitySharedDecls.h"
3.'Classes/iPhone_Sensors.h' file not found
解決同上
解決：刪除對DynamicLibEngineAPI-functions.h和DynamicLibEngineAPI.mm的引用
5.Undefined symbol: __mh_execute_header
_UnityGetAppLoadAddress in CrashReporter.o
解決：找到CrashReporter.mm文件
注釋代碼UnityGetAppLoadAddress、UnityGetAppLoadCommandAddress、UnityGetAppLoadCommandCount
6.重復引用
解決：Unity的main.mm文件和導入的UnityMain.mm重復了 刪除對main.mm的引用即可
7.這個問題剛開始就出現了 我反復刪除添加libil2cpp文件夾貌似自己就好了 （主要是我也不記得怎么修復的了...）
當然你添加libil2cpp文件后會報另一個問題（libil2cpp文件里有些include引用會報錯 排查非常麻煩，感覺加上libil2cpp文件就是不對的操作）
新項目引用SDK
1.引入framework 文件目錄添加MapFileParser文件
2.Build Phrase配置
添加Run Script "$PROJECT_DIR/MapFileParser.sh"
3.添加Copy Files
代碼使用
ViewController.m文件 只需加上如下代碼即可
#import "ViewController.h"
//#import <testliboc/testliboc.h>
#import <testlibocSDK/testlibocSDK.h>
@interface ViewController ()
//Main.storyboard上添加一個view 關聯上即可
@property (nonatomic, weak) IBOutlet UIView* unityContainerView;
@property (nonatomic, strong) UIView* unityView;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor yellowColor];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = CGRectMake(100, 100, 100, 50);
[btn setBackgroundColor:[UIColor redColor]];
[btn addTarget:self action:@selector(aaa) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
}
- (void)aaa{
[[SpaceAppController sharedController] application:[UIApplication sharedApplication] didFinishLaunchingWithOptions:[NSDictionary dictionary]];
[[SpaceAppController sharedController] applicationDidBecomeActive:[UIApplication sharedApplication]];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(applicationWillResignActive) name:UIApplicationWillResignActiveNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(applicationDidBecomeActive) name:UIApplicationDidBecomeActiveNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(applicationWillEnterForeground) name:UIApplicationWillEnterForegroundNotification object:nil];
self.unityView = [SpaceAppController sharedController].unityView;
[self.unityContainerView addSubview:self.unityView];
}
- (void)viewDidLayoutSubviews {
[super viewDidLayoutSubviews];
self.unityView.frame = self.unityContainerView.bounds;
}
- (void)applicationWillResignActive {
[[SpaceAppController sharedController] applicationWillResignActive:[UIApplication sharedApplication]];
}
- (void)applicationDidBecomeActive {
[[SpaceAppController sharedController] applicationDidBecomeActive:[UIApplication sharedApplication]];
}
- (void)applicationWillEnterForeground {
[[SpaceAppController sharedController] applicationWillEnterForeground:[UIApplication sharedApplication]];
}
- (void)dealloc {
[[NSNotificationCenter defaultCenter] removeObserver:self];
[[SpaceAppController sharedController] applicationWillResignActive:[UIApplication sharedApplication]];
}
@end
這里補充一下 之前打包的靜態庫framework的問題
靜態庫打包參考了上一篇Unity文件放到iOS里的配置及上面的參考鏈接還有靜態庫打包的配置（參考我之前寫的framework打包）
打包成功后，項目引入時會報錯（libil2cpp文件找不到），必須把Libraries文件也引入才行，然后運行沒問題，但是當加載Unity時會報錯 (crash occurred >>> il2cpp::vm:MetadataCache::Initialize())
對于這個問題應該是Unity版本不同導致的 他應該是引用不到il2cpp的原因
