Unity iOS嵌入 互動 傳值

專案需要用到iOS和Unity之間的互動, 就捯飭了一下

我專案是Unity工程大, iOS工程小, 所以在是Unity匯出的xcode工程裡嵌入iOS的原生程式碼

先看下我的檔案目錄

iOS 放iOS 原生工程程式碼(我是在這邊做好 測試好才合併的)

Unity 放Unity的原生工程程式碼

Unity_iOS   方Unity匯出的xcode專案(這個也是最後的合併版)

1.先建一個簡單的unity工程(我專案有用到Vuforia 我就先建立了一個簡單的Vuforia的介面)

2.開始匯出xcode 專案(請先確保你的unity可以正常執行 )

3.設定Player Setting  (根據你專案需求配置)

注意:Vuforia工程的話Auto Graphics API 刪除Metal, 單是unity專案不用管它

4.路徑選擇到Unity_iOS檔案下

5.開啟匯出後的工程, 正常的話配置下team 就可以執行

6.建立ARCKRAppController 繼承自 UnityAppController

 把.h .m合併在一起 程式碼如下(先不要編譯,此檔案是要拖到unity工程裡的,在xcode裡寫是有提示方便寫)

#import "UnityAppController.h"
#import <UI/UnityView.h>
#import <UI/UnityViewControllerBase.h>
#import "MyMainViewController.h"
@interface ARCKRAppController :UnityAppController
@property (nonatomic,strong)UINavigationController *navc;
//-(void)createViewHierarchyImpl;
-(void)createUI;
@end
@implementation ARCKRAppController
//iOS8後 createViewHierarchyImpl棄用更改方法為
//-(void)createViewHierarchyImpl{
-(void)createUI{
    _rootController = [[UIViewControlleralloc]init];
    _rootView = [[UIViewalloc]initWithFrame:[UIScreenmainScreen].bounds];
    _rootController.view =_rootView;
    MyMainViewController *vc = [[MyMainViewControlleralloc]init];
    self.navc = [[UINavigationControlleralloc]initWithRootViewController:vc];
    [_rootViewaddSubview:self.navc.view];
   _window.rootViewController =_rootController;
    [_windowbringSubviewToFront:_rootView];
    [_windowmakeKeyAndVisible];
}
@end
IMPL_APP_CONTROLLER_SUBCLASS(ARCKRAppController)
 

7.上面的MyMainViewController 是我的首介面,我是把unity介面直接當做首介面了,你可以用自己的介面

在其他任何你想顯示unity 介面的控制器中加這兩句程式碼就可以 記得檔案字尾改.mm

[self.viewaddSubview:GetAppController().unityView];

GetAppController().unityView.frame = self.view.frame;

 做為首介面 [selfinitUI]; 放在viewDidLoad裡 會縮小unity的介面,所以把它放在viewDidAppear裡了

測試其他介面 在viewDidLoad里加載是正常的;

#import "MyMainViewController.h"
#import <UI/UnityView.h>
#import <UI/UnityViewControllerBase.h>
#import "UnityAppController+ViewHandling.h"
#import <UIKit/UIKit.h>
#import "UserViewController.h"

@interfaceMyMainViewController ()
@end
@implementation MyMainViewController
- (void)viewDidLoad {
    [superviewDidLoad];
    self.view.backgroundColor = [UIColorclearColor];
    self.title [email protected]"MyMain";
}
-(void)initUI{
    [self.viewaddSubview:GetAppController().unityView];
    GetAppController().unityView.frame =self.view.frame;
    UIButton *btn = [UIButtonbuttonWithType:UIButtonTypeSystem];
    btn.frame =CGRectMake(0,0,300,100);
    btn.center =self.view.center;
    [btn setTitle:@"go"forState:UIControlStateNormal];
    [btn addTarget:selfaction:@selector(go)forControlEvents:UIControlEventTouchUpInside];
    [self.viewaddSubview:btn];
}
//寫在viewDidAppear裡,等到原始介面載入完再載入,寫在viewDidLoad裡顯示不是全屏
-(void)viewDidAppear:(BOOL)animated{
    [selfinitUI];
}

-(void)go{
   UserViewController *vc = [[UserViewControlleralloc]init];
   [self.navigationControllerpushViewController:vc animated:YES];
}
- (void)didReceiveMemoryWarning {
    [superdidReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
@end

8.你可以建幾個空介面進行測試跳轉

9.然後把ARCKRAppController.mm 檔案拖到unity工程下 注意檔案存放目錄,並刪除xcode裡的ARCKRAppController.mm

一定要是Assets-Plugins-iOS 這個目錄

10.command + B 編譯,不要重新導,只編譯ARCKRAppController 會自動編譯到xcode專案下

11.現在執行可以 跳轉, 嵌入成功

首先iOS調Unity的方法

使用 Untiy寫好的方法 UnitySendMessage

為了方便直接改MyMain裡go的方法進行測試

#import "MyMainViewController.h"
#import <UI/UnityView.h>
#import <UI/UnityViewControllerBase.h>
#import "UnityAppController+ViewHandling.h"
#import <UIKit/UIKit.h>
#import "UserViewController.h"

@interface MyMainViewController ()
@end

@implementation MyMainViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor clearColor];
    self.title = @"MyMain";
}
-(void)initUI{
     [self.view addSubview:GetAppController().unityView];
       GetAppController().unityView.frame = self.view.frame;
    UIButton *btn = [UIButton buttonWithType:UIButtonTypeSystem];
    btn.frame = CGRectMake(0, 0, 300, 100);
    btn.center = self.view.center;
    [btn setTitle:@"go" forState:UIControlStateNormal];
    [btn addTarget:self action:@selector(go) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn];
}
-(void)viewDidAppear:(BOOL)animated{
    [self initUI];
}

-(void)go{
    //引數1 場景中模型的名字
    //引數2 指令碼名稱方法
    //引數3 想unity傳遞一個char型別的資料
   UnitySendMessage("iOSSendMessageToUnity", "ChangeCameraDirection", "");
}

unity裡程式碼如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class iOSSendMessageToUnity : MonoBehaviour {

    // Use this for initialization
    void Start () {
        
    }
    
    // Update is called once per frame
    void Update () {
        
    }
    public    void ChangeCameraDirection(){
        Debug.Log(@"更改相機方向");
    }
}

Unity 調iOS

我在介面左下角建立了一個button 這個是用來測試呼叫iOS方法的

UnitySendMessageToiOS 準備用作工具類 放所有呼叫iOS的方法

using UnityEngine;
using System.Runtime.InteropServices;

public class UnitySendMessageToiOS : object {

    //匯出按鈕以後將在xcode專案中生成這個按鈕的註冊
    //iOS中的註冊格式

    [DllImport("__Internal")]
    private static extern void _PressShareBtn();

    public static void ShareSceneIniOS(){
        if (Application.platform != RuntimePlatform.OSXEditor) {
            _PressShareBtn ();
        }
    }
}

btton關聯的指令碼 和方法
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MainScene : MonoBehaviour {

    public GameObject shareBtn;

    public void OnShareBtnClick(){
        UnitySendMessageToiOS.ShareSceneIniOS (); 
    }
    // Use this for initialization
    void Start () {
        
    }

    // Update is called once per frame
    void Update () {
        
    }
}

然後到xcode裡, 我建立了一個空的類 用來接收unity 發來的訊息
#import "ReceiveUnitySystemEvent.h"
@interface ReceiveUnitySystemEvent ()

@end

@implementation ReceiveUnitySystemEvent

void _PressShareBtn()
{
    UIAlertView *alert = [[UIAlertView alloc]init];
    [alert setTitle:@"分享];
    [alert setMessage:@"點選了分享 按鈕"];
    [alert addButtonWithTitle:@"確定"];
    [alert show];
}
