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

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 initialization
    void Start () {

    }

    // Update is called once per frame
    void 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);
    }
}

@end

@implementation MeiyuPushSdkC

- (id)init
{
    id object = [super init];

    [[MeiyuPushSdk my_initPush]setDelegate:self];
    //sdk.delegate = self;
    NSLog(@"initMeiyuPushSdkC");
    return object;
}

-(void)cTestResult
{
    UnitySendMessage("Main Camera", "testBtnResult", "成功啦.哇哈哈哈");
}

@end

MeiyuPushSdkC *m_pushSdk = NULL;

#if defined (__cplusplus)
extern "C"
{
#endif

    void 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。
