unity2019版本融合iOS

基本思路：

Xcode 工程創(chuàng)建工作空間，一個(gè)工作空間包含 iOS原生工程，一個(gè)為3D工程。通過UnityFramework.framework 進(jìn)行橋接通信。 unity工程注冊(cè)代理，原生實(shí)現(xiàn)交互方法、
unity 調(diào)取iOS 代理模式交互數(shù)據(jù)。
iOS調(diào)取unity 通過UnityFramework 提供的發(fā)送消息方法。

正文：
Unity 2019.3.a2及更高版本，以及Xcode 9.4及更高版本。
下載Unity 2019.3.a2： https://unity3d.com/alpha/2019.3

1.生成iOS工程
首先在Unity編輯器打開UnityProject項(xiàng)目，選擇Menu -> Window -> Package Manager，因?yàn)?.0.8版本不兼容使用Unity作為庫(kù)，所以要移除Ads資源包，或更新Ads資源包到v 3.*版本。

選擇Menu -> Edit -> Player Settings -> Player -> iOS設(shè)置標(biāo)簽頁(yè) -> Identification Section，設(shè)置有效的Bundle Identification和Signing Team ID，以避免后續(xù)步驟出現(xiàn)Xcode簽名問題。

打開Menu -> File -> Builds Settings，在此選擇并切換平臺(tái)為iOS。將UnityProject項(xiàng)目構(gòu)建到iosBuild文件夾。

2.創(chuàng)建Xcode工作空間
設(shè)置Xcode工作空間
　　Xcode工作空間允許同時(shí)處理多個(gè)項(xiàng)目，并結(jié)合它們的結(jié)果。
　　我們?cè)赬code打開NativeiOSApp.xcodeproj。選擇File -> New -> Workspace，創(chuàng)建工作空間，把它保存在UaaLExample/both.xcworkspace。

關(guān)閉NativeiOSApp.xcodeproj項(xiàng)目，此后的步驟會(huì)在剛創(chuàng)建的工作空間項(xiàng)目完成。

選擇File -> Add Files to “both”，把NativeiOSApp.xcodeproj和第2步生成的Unity-iPhone.xcodeproj添加到相同等級(jí)的工作空間。

3.將iOS工程 加入工作空間
將unity導(dǎo)出工程加入工作空間
如果使用pod 將pods 工程加入工作空間
file -> addFile to ""

3個(gè)工作空間平級(jí)

  1. 添加UnityFramework.framework

5.設(shè)置Data文件夾為 UnityFramework.framework 部分

6.公開橋接文件

工程配置完畢。以下是代碼配置

  1. AppDelegate.mm 修改為 MM
    將 main.m 與AppDelegate 寫入同一個(gè)文件

     #include <UnityFramework/UnityFramework.h>
 #include <UnityFramework/NativeCallProxy.h>
 #include <mach/mach.h>

 UnityFramework* UnityFrameworkLoad()

     NSBundle* bundle = [NSBundle bundleWithPath: bundlePath];
     if ([bundle isLoaded] == false) [bundle load];

     UnityFramework* ufw = [bundle.principalClass getInstance];
     if (![ufw appController])
     {
         // unity is not initialized
         [ufw setExecuteHeader: &_mh_execute_header];
     }
     return ufw;
 }

 void showAlert(NSString* title, NSString* msg) {
   UIAlertController* alert = [UIAlertController     alertControllerWithTitle:title message:msg                                                             preferredStyle:UIAlertControllerStyleAlert];
     UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"Ok" style:UIAlertActionStyleDefault
                                                   handler:^(UIAlertAction * action) {}];
     [alert addAction:defaultAction];
 //    auto delegate = [[UIApplication sharedApplication] delegate];


     UIViewController *vc = [UIApplication     sharedApplication].delegate.window.rootViewController;

   [vc presentViewController:alert animated:YES completion:nil];

采坑經(jīng)驗(yàn)：
1.Data文件夾一定要 包含到 UnityFramework.framework 不然報(bào)錯(cuò)
2.NativeCallProxy.h 包含到 UnityFramework.framework 并且公開

  1. 報(bào)錯(cuò) # [MapFileParser.sh: Permission denied]
    此報(bào)錯(cuò)因文件權(quán)限問題導(dǎo)致
    執(zhí)行指令
    chmod +x /Users/......./MapFileParser.sh （MapFileParser.sh所在的目錄）
    4.unity啟動(dòng)成功 直接跳入3D頁(yè)面
    找到 unity工程中的幾處跳轉(zhuǎn) 全部注釋
    關(guān)鍵字 [window makeKeyAndVisible];

    5.僵尸斷點(diǎn)會(huì)導(dǎo)致untiy工程內(nèi)存持續(xù)增加。不要勾選
