OnEvent in Unity

Add this code:

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

public class NativeAPI {
    [DllImport("__Internal")]
    public static extern void sendMessageToMobileApp(string message);
}

public class ButtonBehavior : MonoBehaviour
{
    public void ButtonPressed()
    {
        NativeAPI.sendMessageToMobileApp("The button has been tapped!");
    }
}

iOS

Build Unity app to [project_root]/unity/builds/ios
Add Unity-iPhone.xcodeproj to your workspace: Menu -> File -> Add Files to [workspace_name]... -> [project_root]/unity/builds/ios/Unity-iPhone.xcodeproj
Add UnityFramework.framework to Frameworks, Libraries, and Embedded Content:
Select Data folder and set a checkbox in the "Target Membership" section to "UnityFramework"
You need to select the NativeCallProxy.h inside the Libraries/Plugins/iOS folder of the Unity-iPhone project and change UnityFramework’s target membership from Project to Public. Don’t forget this step! https://miro.medium.com/max/1400/1*6v9KfxzR6olQNioUp_dFQQ.png
