前面的部分和其他版本大同小异
可以参考Swift3整合Unity5.6
这篇文章再介绍基本的集成内容中,还会补充一些上述文章中没有提到的内容,填了不少的坑
开始吧~~~~~
1. 添加Unity.xcconfig文件到项目
//
// Unity.xcconfig
UNITY_RUNTIME_VERSION = 5.6.1;//U3D版本
UNITY_SCRIPTING_BACKEND = il2cpp;
GCC_THUMB_SUPPORT = NO;
GCC_USE_INDIRECT_FUNCTION_CALLS = NO

HEADER_SEARCH_PATHS = $(inherited) $(UNITY_IOS_EXPORT_PATH) $(UNITY_IOS_EXPORT_PATH)/Classes $(UNITY_IOS_EXPORT_PATH)/Classes/Native $(UNITY_IOS_EXPORT_PATH)/Classes/UI $(UNITY_IOS_EXPORT_PATH)/Libraries $(UNITY_IOS_EXPORT_PATH)/Libraries/libil2cpp/include $(UNITY_IOS_EXPORT_PATH)/Libraries/bdwgc/include;
LIBRARY_SEARCH_PATHS = $(inherited) $(UNITY_IOS_EXPORT_PATH) $(UNITY_IOS_EXPORT_PATH)/Libraries $(UNITY_IOS_EXPORT_PATH)/Libraries/libil2cpp/include;
ENABLE_BITCODE = NO;
//请根据自己的项目修改
SWIFT_OBJC_BRIDGING_HEADER = $(PROJECT_DIR)/$(PRODUCT_NAME)/UnityBridge.h;
OTHER_CFLAGS = -DINIT_SCRIPTING_BACKEND=1;
CLANG_CXX_LANGUAGE_STANDARD = compiler-default;
CLANG_CXX_LIBRARY = libc++;
CLANG_WARN_BOOL_CONVERSION = NO;
CLANG_WARN_CONSTANT_CONVERSION = NO;
CLANG_WARN_DIRECT_OBJC_ISA_USAGE = YES;
CLANG_WARN_EMPTY_BODY = NO;
CLANG_WARN_ENUM_CONVERSION = NO;
CLANG_WARN_INT_CONVERSION = NO;
CLANG_WARN_OBJC_ROOT_CLASS = YES;
CLANG_WARN_UNREACHABLE_CODE = NO;
CLANG_WARN__DUPLICATE_METHOD_MATCH = NO;
GCC_C_LANGUAGE_STANDARD = c99;
GCC_ENABLE_OBJC_EXCEPTIONS = NO;
GCC_PRECOMPILE_PREFIX_HEADER = YES;

GCC_WARN_UNINITIALIZED_AUTOS = NO;
CLANG_WARN_UNREACHABLE_CODE = NO;
GCC_WARN_UNUSED_FUNCTION = NO;
CLANG_WARN__DUPLICATE_METHOD_MATCH = NO;
添加Unity.xcconfig后如下图做相应配置
如果没有集成cocoapods的情况下

2. 添加UnityBridge.h UnityUtils.h UnityUtils.mm 到项目
Snip20180208_52.png
//
// UnityBridge.h
//
// Created by Adam Venturella on 10/28/15.
//
#ifndef UnityBridge_h
#define UnityBridge_h
#import "UnityUtils.h"
#import "UnityAppController.h"
#import "Unity/UnityInterface.h"
#endif /* UnityBridge_h */
/**
* Replacement Function for UnityAppController.h
*
*/
/*
NS_INLINE UnityAppController* GetAppController(){
NSObject* delegate = [UIApplication sharedApplication].delegate;
UnityAppController* currentUnityController = (UnityAppController *)[delegate valueForKey:@"currentUnityController"];
return currentUnityController;
}
*/

//
// UnityUtils.m
//
// Created by Adam Venturella on 10/28/15.
//
// this is taken directly from the unity generated main.mm file.
// if they change that initialization, this will need to be updated
// as well.
#include "RegisterMonoModules.h"
#include "RegisterFeatures.h"
#include
// Hack to work around iOS SDK 4.3 linker problem
// we need at least one __TEXT, __const section entry in main application .o files
// to get this section emitted at right time and so avoid LC_ENCRYPTION_INFO size miscalculation
static const int constsection = 0;
void UnityInitTrampoline();
extern "C" void custom_unity_init(int argc, char* argv[])
{
@autoreleasepool
{
UnityInitTrampoline();
// UnityParseCommandLine(argc, argv); //Unity 5.3+
UnityInitRuntime(argc, argv); //Unity 5.6+，5.4和5.5用哪个我没试过，可以根据报错情况选择。
RegisterMonoModules();
NSLog(@"-> registered mono modules %p\n", &constsection);
RegisterFeatures();
// iOS terminates open sockets when an application enters background mode.
// The next write to any of such socket causes SIGPIPE signal being raised,
// even if the request has been done from scripting side. This disables the
// signal and allows Mono to throw a proper C# exception.
std::signal(SIGPIPE, SIG_IGN);
}
}

3. 将Unity导出的文件导入到xcode工程中
Snip20180208_53.png
4.设置配置
image.png
注意注意!!!这个很重要 debug和release都要加上
-DRUNTIME_IL2CPP=1否则打包的版本就会有问题
Snip20180208_56.png
注意注意!!!一般我们只需要加-DRUNTIME_IL2CPP=1,如果出现
was compiled with optimization - stepping may behave oddly; variables may not be available.
加要加上
I had the same issue and I solve it adding to Apple LLVM - Custom Compiler FLags:
Other C Flags: -DRUNTIME_IL2CPP=1
5.变更Unity里的方法
找到main.mm
//int main(int argc, char* argv[])
//{
// signed long long startTime = mach_absolute_time();
// @autoreleasepool
// {
// UnitySetStartupTime(startTime);
// UnityInitTrampoline();
// UnityInitRuntime(argc, argv);
//
// RegisterMonoModules();
// NSLog(@"-> registered mono modules %p\n", &constsection);
// RegisterFeatures();
//
// // iOS terminates open sockets when an application enters background mode.
// // The next write to any of such socket causes SIGPIPE signal being raised,
// // even if the request has been done from scripting side. This disables the
// // signal and allows Mono to throw a proper C# exception.
// std::signal(SIGPIPE, SIG_IGN);
//
// UIApplicationMain(argc, argv, nil, [NSString stringWithUTF8String: AppControllerClassName]);
// }
//
// return 0;
//}
//替换为
int main_unity_default(int argc, char* argv[])
{
@autoreleasepool
{
UnityInitTrampoline();
// UnityParseCommandLine(argc, argv); //Unity 5.3+
UnityInitRuntime(argc, argv); //Unity 5.6+，5.4和5.5用哪个我没试过，可以根据报错情况选择。
RegisterMonoModules();
NSLog(@"-> registered mono modules %p\n", &constsection);
RegisterFeatures();
// iOS terminates open sockets when an application enters background mode.
// The next write to any of such socket causes SIGPIPE signal being raised,
// even if the request has been done from scripting side. This disables the
// signal and allows Mono to throw a proper C# exception.
std::signal(SIGPIPE, SIG_IGN);
//UIApplicationMain(argc, argv, nil, [NSString stringWithUTF8String:AppControllerClassName]);
// UIApplicationMain(argc, argv, nil, NSStringFromClass([UnitySubAppDelegate class]));
UIApplicationMain(argc, argv, nil, [NSString stringWithUTF8String:AppControllerClassName]);
}
return 0;
}

找到UnityAppController.h
#import
//注释该方法
//inline UnityAppController* GetAppController()
//{
// return (UnityAppController*)[UIApplication sharedApplication].delegate;
//}
//替换为此方法
NS_INLINE UnityAppController* GetAppController()
{
NSObject* delegate = [UIApplication sharedApplication].delegate;
UnityAppController* currentUnityController = (UnityAppController *)[delegate valueForKey:@"currentUnityController"];
return currentUnityController;
}

找到SplashScreen类 修改这个方法,之前忘记加上
void ShowSplashScreen(UIWindow* window)
{
_controller = [[SplashScreenController alloc] init];
[_controller create: window];
}
添加一个新的main.swift文件到项目
//
// main.swift
// SwiftCombineUnityProject
//

import Foundation
import UIKit
custom_unity_init(CommandLine.argc, CommandLine.unsafeArgv)
UIApplicationMain(
CommandLine.argc,
UnsafeMutableRawPointer(CommandLine.unsafeArgv)
.bindMemory(
to: UnsafeMutablePointer.self,
capacity: Int(CommandLine.argc)),
nil,
NSStringFromClass(AppDelegate.self)
)

找到AppDelegate.swift并作如下修改
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
window?.backgroundColor = UIColor.white;
window?.rootViewController = ViewController();
currentUnityController = UnityAppController()
currentUnityController.application(application, didFinishLaunchingWithOptions: launchOptions)
window!.makeKeyAndVisible()
return true
}
func applicationWillResignActive(_ application: UIApplication) {
currentUnityController.applicationWillResignActive(application)
}
func applicationDidEnterBackground(_ application: UIApplication) {
currentUnityController.applicationDidEnterBackground(application)
}
func applicationWillEnterForeground(_ application: UIApplication) {
currentUnityController.applicationWillEnterForeground(application)
}
func applicationDidBecomeActive(_ application: UIApplication) {
currentUnityController.applicationDidBecomeActive(application)
}
func applicationWillTerminate(_ application: UIApplication) {
currentUnityController.applicationWillTerminate(application)
}
OK~~~一切都搞定了
显示U3D view
let unityview = UnityGetGLView()
unityview?.frame = CGRect(x:0,y:0,width:self.view.frame.width,height:self.view.frame.size.height/2);
unityview?.center = self.view.center
self.view.addSubview(unityview!)
self.view.bringSubview(toFront: unityview!)
如果出现AVFoundationMediaLoader之类的错误
添加mediatool库
总结一下~
接进去就是一个大坑,不是领导要求我才不接.....
