网上说的教程太复杂，这里我给个最简单版本的

但是首先你要学会ios打包发布 https://www.cnblogs.com/sanyejun/p/8308873.html

第一步 新建一个NativeBinding.mm文件在上图这个位置，名字随便，别的也行

里面的代码

extern "C" {
    void FooPluginFunction() {
        //打log
        NSLog(@"Hello World!");
        //回调unity
        UnitySendMessage("OSEvent","testBtnResult", "chuang_chuang");
    }
}

如果这个方法调用成功，那么xcode控制台会打log，并且回调unity方法  testBtnResult

新建物体，挂上脚本

这个脚本

using System.Collections;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using UnityEngine;
using UnityEngine.UI;

public class CallOS : MonoBehaviour {

    public Button testButton;
    public Text text;

    // Use this for initialization
    void Start () {
        int a = 1;
        testButton.onClick.AddListener(delegate
        {
            Debug.Log("click");
            text.text = "haha" + a++;
            if (Application.platform == RuntimePlatform.IPhonePlayer)
            {
                //点击按钮触发
                FooPluginFunction();
            }
        });
    }
    

    //ios原生方法接口，方法名和mm文件里面的方法相同
    [DllImport("__Internal")]
    static extern void FooPluginFunction();

    //objective-c方法的回调
    public void testBtnResult(string msg)
    {
        Debug.Log("btnPressSuccessssssssssss:" + msg);
    }
}
