unity 与oc、java交互
1.unity cs 书写基类PlatformFactory.cs
using System.Collections;using System.Collections.Generic;using UnityEngine;using System;public class PlatformFactory { protected static PlatformFactory _Instance = null; public static PlatformFactory Instance { get { if (null == _Instance) { _Instance = CreatePlatformInterface(); } return _Instance; } } static PlatformFactory CreatePlatformInterface() {#if UNITY_IOS && !UNITY_EDITOR _Instance = new IOSPlatform();#elif UNITY_ANDROID && !UNITY_EDITOR _Instance = new AndroidPlatform();#else _Instance = new EditorPlatform();#endif return _Instance; } public virtual void initSDK() { } public virtual void loadInterAd() { } public virtual void showInterAd() { } public virtual void loadRewardedVideo() { } public virtual void showRewardedVideo(string tag,Action<string> succeed = null,Action<string> fail = null) { } /// <summary> /// Tea平台打点 /// </summary> /// <param name="custom"></param> /// <param name="dic"></param> public virtual void TeaAnalystic(string custom, Dictionary<string, string> dic) { } public virtual void GameQuit() { }}

From JAVA to U3D
UnityPlayer.UnitySendMessage("AndroidPlatformWrapper",arg2,arg1);
4.From OC to U3D
1)分为两种办法：一种是通过UnitySendMessage方法来调用Unity所定义的方法。另一种方法则是通过入口参数，传入一个U3D的非托管方法，然后调用该方法即可。两种方式的对比如下：
UnitySendMessage方式非托管方法方式接口声明固定，只能是void method(string message)。接口灵活，可以为任意接口。不能带有返回值可以带返回值必须要挂载到对象后才能调用。可以不用挂载对象，但需要通过接口传入该调用方法
2)UnitySendMessage
oc书写如下：
UnitySendMessage("Main Camera", "callback", resultStr.UTF8String);
3）非托管方式 cs代码如下
private static extern void initHwAds( string jsonStr, CallbackDelegate callBack = null); public static void initSDK() { Debug.Log("initSDK"); initHwAds("121212", initSDKCallback); }
oc代码如下
typedef void (*CallbackDelegate)(const char *object); CallbackDelegate call; + (void)ToUnity:(char *) str{ call(str); } void initHwAds( char *str ,CallbackDelegate callback){ NSLog(@"initHwAds complete111111 %s",str); //callback(str); call = callback; ; }
5.DllImport 介绍
Unity本身对第三方C/C++/Objective-C编写的类库具有广泛的支持。不过不能使用Using的方式来引用，需要使用DllImport的方式来引用，一下是官方文档内容
Unity has extensive support for native plug-ins, which are libraries of native code written in C, C++, Objective-C, etc. Plug-ins allow your game code (written in Javascript or C#) to call functions from these libraries. This feature allows Unity to integrate with middleware libraries or existing C/C++ game code.（
Unity对本地插件有广泛的支持，这些插件是用C、c++、Objective-C等语言编写的本地代码库。插件允许游戏代码(用Javascript或c#编写)从这些库调用函数。这个特性允许Unity集成中间件库或现有的C/ c++游戏代码。）
6.MonoPInvokeCallback标签声明
声明一个静态方法，并使用MonoPInvokeCallback特性来标记为回调方法，目的是让iOS中调用该方法时可以转换为对应的托管方法。如：
static void PlatformCallback_FinishInterAd(string jsonStr) { Debug.Log("AndroidPlatformWrapper PlatformCallback_FinishInterAd:"+jsonStr); }
注意：MonoPInvokeCallback特性参数是上一步中定义的非托管delegate。方法的声明一定要与delegate定义一致，并且必须为static进行修饰（iOS不支持非静态方法回调），否则会导致异常。
7.类型传递
对于基础类型数据（如：int、double、string等）是可以直接从U3D中传递给iOS的。具体对应关系如下表所示
