## 前言 ##

最近有个项目需要在swift工程中引入Unity项目，查了不少的资料，现在做一个总结。

### IDE的版本 ###

*  Xcode 11.4
 *  Swift 5.1
 *  Unity2017.4.34f1

## 1 准备unity项目，swift项目并做整合 ##

从Unity导出一个iOS项目，先保证导出的项目是可以运行的。

新建一个Swift项目，在工程根目录下创建Unity目录，把Unity项目中的Classes、Library和data三个文件直接拖入到项目中。Classes和Library选择Create groups选项，data选择Create folder references选项。

### 2.9 配置Header Search Paths ###

一定要注意路径，根据工程配置

$(inherited)
    "$(SRCROOT)"
    "$(SRCROOT)/Plane/Unity"
    "$(SRCROOT)/Plane/Unity/Classes"
    $(SRCROOT)/Plane/Unity/Classes/Native
    $(SRCROOT)/Plane/Unity/Libraries/bdwgc/include

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmdodWk1MjM_size_16_color_FFFFFF_t_70 14][]

### 2.10 配置Library Search Paths ###

$(inherited)
    "$(SRCROOT)"
    $(PROJECT_DIR)/Plane/Unity/Libraries

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmdodWk1MjM_size_16_color_FFFFFF_t_70 15][]

### 2.14 添加依赖库 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmdodWk1MjM_size_16_color_FFFFFF_t_70 19][]

## 3.修改代码文件 ##

### 3.1 添加一个新的main.swift文件 ###

import UIKit
    custom_unity_init(CommandLine.argc, CommandLine.unsafeArgv)
    UIApplicationMain(
       CommandLine.argc,
       UnsafeMutableRawPointer(CommandLine.unsafeArgv)
           .bindMemory(
               to: UnsafeMutablePointer<Int8>.self,
               capacity: Int(CommandLine.argc)),
       nil,
       NSStringFromClass(AppDelegate.self)
    )

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmdodWk1MjM_size_16_color_FFFFFF_t_70 20][]

### 3.2 删除SceneDelegate.swift 并修改Info.pllist文件中的UIApplicationSceneManifest关键字 ###

AppDelegate.swift 删除不需要的代码

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmdodWk1MjM_size_16_color_FFFFFF_t_70 21][]

到目前为止 工程应该可以跑起来了！

### 3.3 替换AppDelegate.swift文件 ###

class AppDelegate: UIResponder, UIApplicationDelegate {
    
            var window: UIWindow?
            var currentUnityController: UnityAppController!
    
            var isUnityRunning = false
            var application: UIApplication?
    
            func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
                // Override point for customization after application launch.
                self.application = application
                currentUnityController = UnityAppController()
                currentUnityController.application(application, didFinishLaunchingWithOptions:launchOptions)
    
                return true
            }
    
            func applicationWillResignActive(_ application: UIApplication) {
                if isUnityRunning {
                    currentUnityController.applicationWillResignActive(application)
                }
            }
    
            func applicationDidEnterBackground(_ application: UIApplication) {
                if isUnityRunning {
                    currentUnityController.applicationDidEnterBackground(application)
                }
            }
    
            func applicationWillEnterForeground(_ application: UIApplication) {
    
                if isUnityRunning {
                    currentUnityController.applicationWillEnterForeground(application)
                }
            }
    
            func applicationDidBecomeActive(_ application: UIApplication) {
    
                if isUnityRunning {
                    currentUnityController.applicationDidBecomeActive(application)
                }
            }
    
            func applicationWillTerminate(_ application: UIApplication) {
                currentUnityController.applicationWillTerminate(application)
            }
    
            func startUnity() {
                if !isUnityRunning
                {
                    isUnityRunning = true
                    currentUnityController.applicationDidBecomeActive(application!)
                }
            }
    
            func stopUnity() {
                if isUnityRunning {
                    currentUnityController.applicationWillResignActive(application!)
                    isUnityRunning = false
                }
            }
    }

### 3.4 修改UnityAppController.mm文件 ###

UnityAppController.mm 在startUnity方法结尾添加

[[NSNotificationCenter defaultCenter] postNotificationName: @"UnityReady" object:self];

### 3.5 修改ViewController.swift文件 ###

import UIKit
    
    class ViewController: UIViewController {
    
        
        override func viewDidLoad() {
            super.viewDidLoad()
            if let appDelegate = UIApplication.shared.delegate as? AppDelegate
            {
              appDelegate.startUnity()
              NotificationCenter.default.addObserver(self, selector: #selector(handleUnityReady), name: NSNotification.Name("UnityReady"), object: nil)
            }
            
            // Do any additional setup after loading the view.
        }
    
         @objc func handleUnityReady(){
          
           
              showUnitySubView()
                
        }
        
        
        func showUnitySubView() {
               if let unityView = UnityGetGLView() {
                   view.addSubview(unityView)
               }
        }
        
        
    }

## 4.大功告成 ##

至此unity界面就展示出来了。
