iOS项目集成Unity视图

“Unity调研”

正文

最近接了个集成Unity的需求，网上找了找教程，顺便自己踩踩坑。

运行篇

主项目左下角 add files to “项目名” 添加Unity 的 target
修改unity签名证书并切换target可以正常运行
运行报错MapFileParser.sh: Permission denied 解决方案如下，进行控制台sudo授权

	sudo chmod 777 /Users/xxx/myProject/hznz_iOS/EnvironmentSim/MapFileParser.sh 

general 添加UnityFramework.framework 默认embed为 Embed & Sign
删除build Phases中Link Binary 中的 status为Required 的UnityFramework.framework

添加桥接文件：

  #import <UnityFramework/UnityFramework.h>

delegate 添加 unityFramework 的初始化方法

  func initUnityFramework() {
     unityFramework = getUnityFramework()
     if let unityframework = self.unityFramework {
         unityframework.setDataBundleId("com.unity3d.framework")
         unityframework.register(self)
         unityframework.runEmbedded(withArgc: CommandLine.argc, argv: CommandLine.unsafeArgv, appLaunchOpts: appLaunchOpts)
     }
 }
  private func getUnityFramework() -> UnityFramework? {
      let bundlePath: String = Bundle.main.bundlePath + "/Frameworks/UnityFramework.framework"
 
      let bundle = Bundle(path: bundlePath)
      if bundle?.isLoaded == false {
          bundle?.load()
      }
         
      let ufw = bundle?.principalClass?.getInstance()
      if ufw?.appController() == nil {
          let machineHeader = UnsafeMutablePointer<MachHeader>.allocate(capacity: 1)
          machineHeader.pointee = _mh_execute_header
             
          ufw!.setExecuteHeader(machineHeader)
      }
      return ufw
  }
     
  func unityIsInitialized( ) -> Bool {
      return (self.unityFramework != nil && self.unityFramework?.appController() != nil)
  }
     
  // 卸载unity
  private func unloadUnityInternal() {
      if let unityFramework = self.unityFramework {
          unityFramework.unregisterFrameworkListener(self)
      }
      self.unityFramework = nil
  }
  // 监听
   func unityDidUnload(_ notification: Notification!) {
       unloadUnityInternal()
   }
      
      
   func unityDidQuit(_ notification: Notification!) {
       unloadUnityInternal()
   }

需要调用视图的位置先调用
```
  appDelegate.initUnityFramework()
```

然后会整屏切换到unity,需要执行

  appDelegate.window?.makeKeyAndVisible()

  guard let unityRootView = appDelegate.unityFramework?.appController().rootView else {
         return
 }

拿到unity并且改变frame，进行视图操作即可
初始化要在拿视图前一段时间操作，不然unity视图显示不出来
两端交互调用待后续对接

打包篇

打包报错

	#import <UnityFramework/UnityFramework.h> not find

解决方案：项目中添加 Header Search Path 添加一条 $(PROJECT_DIR)/IOSProject/UnityFramework.framework/Headers
