转移到iosiphone代码 转移到ios 代码

一直想抽空整理一下unity原生工程导入iOS原生工程中的详细步骤。做iOS+vuforia+unity开发这么长时间了。从最初的小小白到现在的小白。中间趟过了好多的坑。也有一些的小小收货。做一个喜欢总结的人。好了废话不多说了。上干货。本人用的是unity 5.4.0f3 + Xcode 7.2。个人认为这个版本的影响不是很大的。以下的导入资源过程大家根据实际需要去选择是否拷贝资源到原生工程中。（copy if need）

 

一、unity导出工程一开始是这样子的：

 

 

二、unity导入原生工程的准备工作。

1.将一些必要的文件导入iOS Native工程中去

1>将Classes 和 Libraries 文件夹以 下面的方式导入自己的工程中

 

2>将Data 文件夹以下面的方式导入工程中

 

3>删除Native文件夹下的所有.h文件的引用。并将cpp文件导入工程引入。

 

清除native中所有的.h引用。为了更快的删除定位到这些.h文件。首先选定Native文件夹

 

然后进行这样的操作，注意一定要选择Remove Reference。千万不要选择Move to Trash（下面截图只是为了演示一下删除框。类名忽略不要对号删除，并不是Native中的头文件）然后再将Native中的cpp文件拖入到工程。勾选1、2、4方框。

 

4>.然后对应删除Libraries-->libil2cpp文件夹。删除方法同Native中的.h文件的移除。

 

 

三、添加引用库文件

 

其中因为我用了pod的缘故。libPods库可以忽略。

 

四、关闭bitcode

在build settings中bitcode关闭。

 

五、在 other Linker Flags 添加

-weak_framework CoreMotion -weak-lSystem

 

 

六、在Header Search Path 添加下面这些头文件引用~

SRCROOT/../../iOS/unity2iOSSRCROOT/../../iOS/unity2iOS{SRCROOT}/../../iOS/unity2iOS/Classes
SRCROOT/../../iOS/unity2iOS/Classes/NativeSRCROOT/../../iOS/unity2iOS/Classes/Native{SRCROOT}/../../iOS/unity2iOS/Libraries
SRCROOT/../../iOS/unity2iOS/Libraries/libil2cpp/includeSRCROOT/../../iOS/unity2iOS/Libraries/libil2cpp/include{SRCROOT}/../../iOS/unity2iOS/Libraries/Plugins/iOS

 

 

 

七、在Library Search Path 中添加

SRCROOT/../../iOS/unity2iOSSRCROOT/../../iOS/unity2iOS{SRCROOT}/../../iOS/unity2iOS/Libraries
${SRCROOT}/../../iOS/unity2iOS/Libraries/Plugins/iOS

 

 

 

八、在other C Flags 中添加 -DINIT_SCRIPTING_BACKEND=1 同是在 other C++ Flags中出现

 

改为C99

 

改PCH(将两个pch文件合并)

跟着下面的图片做设置更改

 

在user-Defined 添加如下

GCC_THUMB_SUPPORT NO
GCC_USE_INDIRECT_FUNCTION_CALLS NO
UNITY_RUNTIME_VERSION 5.4.0f3
UNITY_SCRIPTING_BACKEND il2cpp

以上都要根据自己工程的具体情况添加。大家切记。

 

九、添加配置脚本RUN SCRIPT(注意按照自己工程中的脚本位置配置)

 

 

十、更改main.m文件为main.mm文件。将Classes中的main.mm中的内容合并到原来工程的main.mm工程中。然后删除Classes中的main文件。

#import  <UIKit/UIKit.h>
#import  "AppDelegate.h"
#include "RegisterMonoModules.h"
#include "RegisterFeatures.h"
#include <csignal>

// Hack to work around iOS SDK 4.3 linker problem
// we need at least one __TEXT, __const section entry in main application .o files

void UnityInitTrampoline();

// WARNING: this MUST be c decl (NSString ctor will be called after +load, so we cant really change its value)
/**

const char* AppControllerClassName = "AppDelegate";

int main(int argc, char* argv[])
{
    @autoreleasepool
    {
        UnityInitTrampoline();
        UnityParseCommandLine(argc, argv);
        
        RegisterMonoModules();
        NSLog(@"-> registered mono modules %p\n", &constsection);
        RegisterFeatures();
        std::signal(SIGPIPE, SIG_IGN);
        NSString *ss = NSStringFromClass([AppDelegate class]);
        UIApplicationMain(argc, argv, nil,ss);
    }
    return 0;
}

#if TARGET_IPHONE_SIMULATOR && TARGET_TVOS_SIMULATOR

#include <pthread.h>

extern "C" int pthread_cond_init$UNIX2003(pthread_cond_t *cond, const pthread_condattr_t *attr)
{ return pthread_cond_init(cond, attr); }
extern "C" int pthread_cond_destroy$UNIX2003(pthread_cond_t *cond)
{ return pthread_cond_destroy(cond); }
extern "C" int pthread_cond_wait$UNIX2003(pthread_cond_t *cond, pthread_mutex_t *mutex)
{ return pthread_cond_wait(cond, mutex); }
extern "C" int pthread_cond_timedwait$UNIX2003(pthread_cond_t *cond, pthread_mutex_t *mutex,
                                               const struct timespec *abstime)
{ return pthread_cond_timedwait(cond, mutex, abstime); }

#endif // TARGET_IPHONE_SIMULATOR && TARGET_TVOS_SIMULATOR

 

十一、在pch文件中添加 #import "UnityAppController.h"。然后更改AppDelegate

//
//  AppDelegate.h
//  //
//  Created by Aaron on 16/11/17.
//  Copyright © 2016年 Aaron. All rights reserved.
//

#import <UIKit/UIKit.h>
@class UnityAppController;

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;
@property (nonatomic , strong)UIWindow *unityWindow;
@property (nonatomic , strong)UnityAppController *unityVC;

- (void)showUnityWindow;
- (void)hideUnityWindow;
- (void)shouldAttachRenderDelegate;



@end

 在AppDelegate.mm(因为有混编，本来变一个main.mm文件就可以了。这里也变过来双保险)

首先添加：

//
//  AppDelegate.m
//  //
//  Created by Aaron on 16/11/17.
//  Copyright © 2016年 Aaron. All rights reserved.
//

#import "AppDelegate.h"
#import "HomeViewController.h"
#import "UnityAppController.h"
#import "VuforiaRenderDelegate.h"

extern "C" void VuforiaSetGraphicsDevice(void* device, int deviceType, int eventType);
extern "C" void VuforiaRenderEvent(int marker);

@interface AppDelegate ()
{
    UIButton *_backBtn;
}

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.window.backgroundColor = [UIColor whiteColor];
    [application setStatusBarStyle:UIStatusBarStyleLightContent];
    //unity
    self.unityVC = [[UnityAppController alloc] init];
    [self.unityVC application:application didFinishLaunchingWithOptions:launchOptions];
    HomeViewController *homeVC = [[HomeViewController alloc] init];
    BaseNavViewController *mainNav = [[BaseNavViewController alloc] initWithRootViewController:homeVC];
    self.window.rootViewController = mainNav;
    [self.window makeKeyAndVisible];
    
    return YES;
}



- (void)applicationWillResignActive:(UIApplication *)application
{
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
    [self.unityVC applicationWillResignActive:application];
}

- (void)applicationDidEnterBackground:(UIApplication *)application
{
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
    [self.unityVC applicationDidEnterBackground:application];
}

- (void)applicationWillEnterForeground:(UIApplication *)application
{
    // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
    [self.unityVC applicationWillEnterForeground:application];
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    [self.unityVC applicationDidBecomeActive:application];
}

- (void)applicationWillTerminate:(UIApplication *)application
{
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    [self.unityVC applicationWillTerminate:application];
}

#pragma mark -
#pragma mark ---------------unity开启与隐藏
- (UIWindow *)unityWindow
{
    if (!_unityWindow) {
        _unityWindow = UnityGetMainWindow();
    }
    return _unityWindow;
}
- (void)showUnityWindow
{
    [self.unityWindow makeKeyAndVisible];
    
    _backBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    [_backBtn setImage:[UIImage imageNamed:@"返回icon"] forState:UIControlStateNormal];
    [self.unityWindow addSubview:_backBtn];
    [_backBtn addTarget:self action:@selector(hideUnityWindow) forControlEvents:UIControlEventTouchUpInside];
    [_backBtn mas_makeConstraints:^(MASConstraintMaker *make)
    {
        make.top.equalTo(_unityWindow).offset(30);
        make.left.equalTo(_unityWindow).offset(15);
        make.width.mas_equalTo(50);
        make.height.mas_equalTo(50);
    }];
}
- (void)hideUnityWindow
{
    [self.window makeKeyAndVisible];
}
- (void)shouldAttachRenderDelegate
{
    UnityRegisterRenderingPlugin(&VuforiaSetGraphicsDevice, &VuforiaRenderEvent);
}

@end

 

十二、在unityappcontroller中需要做的配置就是,首先在unityAppController.h中更改GetAppController（）方法（当然要先引入#import "AppDelegate.h"）

NS_INLINE UnityAppController*    GetAppController()
{
    AppDelegate *dele = (AppDelegate *)[UIApplication sharedApplication].delegate;
    return (UnityAppController *)dele.unityVC;
}

在.mm文件中重写shouldAttachRenderDelegate

方法

- (void)shouldAttachRenderDelegate
{
    AppDelegate *deleg = [UIApplication sharedApplication].delegate;
    [deleg shouldAttachRenderDelegate];
}

至此，导入工作已经做完了。愉快地去玩耍吧。
