Unity3D 与 objective-c 之间数据交互。iOS SDK接口封装Unity3D接口

Unity 3D 简单工程的创建。与Xcode 导出到iOS 平台请看这 

Unity3D 学习 创建简单的按钮、相应事件

Unity C# 代码

 

using UnityEngine;
using System.Collections;
using System.Runtime.InteropServices;public class testFeil : MonoBehaviour {[DllImport("__Internal")]private static extern void c_ctest();// Use this for initializationvoid Start () {}// Update is called once per framevoid Update () {}void OnGUI()  {  //开始按钮  创建了一个按钮。  if(GUI.Button(new Rect(20,100,200,50),"qingyun "))  {  //System.Console.WriteLine("hello world");print("hello qingyun !");c_ctest();  // Debug.Log("up.up");}  } void testResult (string msg){Debug.Log("testResult:" +msg);}//这个是C#里的一个回调。用来接收数据是否传送成功。----这里的作用就是OC里的回调。void testBtnResult (string msg){Debug.Log ("btnPressSuccessssssssssss:"+msg);}
}

 

 

.mm 文件里的OC  与 C 接口

{UnitySendMessage("Main Camera", "testBtnResult", "成功啦.哇哈哈哈");
}@endMeiyuPushSdkC *m_pushSdk = NULL;#if defined (__cplusplus)
extern "C"
{
#endifvoid c_ctest(){if(m_pushSdk == NULL){m_pushSdk = [[MeiyuPushSdkC alloc]init];}MeiyuPushSdk *m = [MeiyuPushSdk my_initPush];//objc_msgSend(obj, @selector(setName:),@"balabala");[m cTest];NSLog(@"testSuccess---------");UnitySendMessage("Main Camera", "testResult", "-10862904$_^_$接口调用失败");}#if defined (__cplusplus)
}
#endif

 

 这样就把Unity3d 与OC 连到了一起。
