Unity iOS嵌入 交互 传值

项目需要用到iOS和Unity之间的交互, 就捯饬了一下

我项目是Unity工程大, iOS工程小, 所以在是Unity导出的xcode工程里嵌入iOS的原生代码

先看下我的文件目录

iOS 放iOS 原生工程代码(我是在这边做好 测试好才合并的)

Unity 放Unity的原生工程代码

Unity_iOS   方Unity导出的xcode项目(这个也是最后的合并版)

 

1.先建一个简单的unity工程(我项目有用到Vuforia 我就先创建了一个简单的Vuforia的界面)

2.开始导出xcode 项目(请先确保你的unity可以正常运行 )

3.设置Player Setting  (根据你项目需求配置)

注意:Vuforia工程的话Auto Graphics API 删除Metal, 单是unity项目不用管它

4.路径选择到Unity_iOS文件下

5.打开导出后的工程, 正常的话配置下team 就可以运行

6.创建ARCKRAppController 继承自 UnityAppController

 把.h .m合并在一起 代码如下(先不要编译,此文件是要拖到unity工程里的,在xcode里写是有提示方便写)

 

 

#import "UnityAppController.h"
#import 
#import 
#import "MyMainViewController.h"
@interface ARCKRAppController :UnityAppController
@property (nonatomic,strong)UINavigationController *navc;
//-(void)createViewHierarchyImpl;
-(void)createUI;
@end
@implementation ARCKRAppController
//iOS8后 createViewHierarchyImpl弃用更改方法为
//-(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 是我的首界面,我是把unity界面直接当做首界面了,你可以用自己的界面

 

 

在其他任何你想显示unity 界面的控制器中加这两句代码就可以 记得文件后缀改.mm

[self.view addSubview:GetAppController().unityView];

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

 做为首界面 [self initUI]; 放在viewDidLoad里 会缩小unity的界面,所以把它放在viewDidAppear里了

测试其他界面 在viewDidLoad里加载是正常的;

 

#import "MyMainViewController.h"
#import 
#import 
#import "UnityAppController+ViewHandling.h"
#import 
#import "UserViewController.h"

@interfaceMyMainViewController ()
@end
@implementation MyMainViewController
- (void)viewDidLoad {
    [superviewDidLoad];
    self.view.backgroundColor = [UIColorclearColor];
    self.title =@"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];
}
//写在viewDidAppear里,等到原始界面加载完再加载,写在viewDidLoad里显示不是全屏
-(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.你可以建几个空界面进行测试跳转

 

9.然后把ARCKRAppController.mm 文件拖到unity工程下 注意文件存放目录,并删除xcode里的ARCKRAppController.mm

一定要是Assets-Plugins-iOS 这个目录

10.command + B 编译,不要重新导,只编译ARCKRAppController 会自动编译到xcode项目下

 

11.现在运行可以 跳转, 嵌入成功

 

 

首先iOS调Unity的方法

使用 Untiy写好的方法 UnitySendMessage

为了方便直接改MyMain里go的方法进行测试

 

 

#import "MyMainViewController.h"
#import 
#import 
#import "UnityAppController+ViewHandling.h"
#import 
#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{
    //参数1 场景中模型的名字
    //参数2 脚本名称方法
    //参数3 想unity传递一个char类型的数据
   UnitySendMessage("iOSSendMessageToUnity", "ChangeCameraDirection", "");
}

 

 

unity里代码如下

 

 

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(@"更改相机方向");
    }
}

 

 

 

 

Unity 调iOS

我在界面左下角创建了一个button 这个是用来测试调用iOS方法的

UnitySendMessageToiOS 准备用作工具类 放所有调用iOS的方法

 

using UnityEngine;
using System.Runtime.InteropServices;

public class UnitySendMessageToiOS : object {

    //导出按钮以后将在xcode项目中生成这个按钮的注册
    //iOS中的注册格式

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

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

btton关联的脚本 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 () {
        
    }
}

然后到xcode里, 我创建了一个空的类 用来接收unity 发来的消息
#import "ReceiveUnitySystemEvent.h"
@interface ReceiveUnitySystemEvent ()

@end

@implementation ReceiveUnitySystemEvent

void _PressShareBtn()
{
    UIAlertView *alert = [[UIAlertView alloc]init];
    [alert setTitle:@"分享];
    [alert setMessage:@"点击了分享 按钮"];
    [alert addButtonWithTitle:@"确定"];
    [alert show];
}
