From U3D to JAVA

object[] paramArray = new object[3]; paramArray[0] = "showInterAd"; paramArray[1] = "PlatformCallback_FinishInterAd"; paramArray[2] = "PlatformCallback_FailedInterAd"; if (jo != null) jo.Call("showHwInterAd", paramArray);

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
[DllImport("__Internal")] 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 complete  111111 %s",str);       //callback(str);       call = callback;       [IOSJSHelper initAd]; }
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：
[MonoPInvokeCallback(typeof(CallbackDelegate))] 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
