ios端ibeacon 集成到unity

背景：项目要实现unity3d调用ibeacon小范围内定位的功能，无奈直接集成在unity里的ibeacon发布ios版之后，只要ibeacon设备灯不亮就获取不到范围，多次调试未果，最终决定从ios端集成，再通过unity调用，亲测成功，简单记录一下。直接贴代码

到此 oc处理结束    下面是unity调用代码
/***********************unity代码**********************/

using System.Runtime.InteropServices; 

public class mytest : MonoBehaviour {

    [DllImport("__Internal")]

    private static extern void pushUUID();
    #endif

以上是做的引用和声明

接下来在你需要的地方 调用

        #if UNITY_IPHONE || UNITY_TVOS

        pushUUID();

        #else

到此全部结束，有错误的地方 欢迎纠正。
