一、C#调用OC

OC代码：
//// CallOC.m// UnityFramework//// Created by 飞杨 on 22.11.22.//#import "CallOC.h"#if defined (__cplusplus)extern "C"{#endif //基础调用 void test() { NSLog(@"call test"); } //调用时传入参数 void testInt(int param) { NSLog(@"call testInt%d",param); } //调用时传入字符串参数 void testString(const char * param) { NSString *s = [NSString stringWithUTF8String:param]; NSLog(@"call testString:%@",s); } //调用并返回值 bool testReturn() { return false; } //调用并返回字符串 const char* testReturnString() { NSString *privacyUrl = @"testReturnString"; return strdup(privacyUrl.UTF8String); } #if defined (__cplusplus)}#endif
C#代码:
using System.Collections;using System.Collections.Generic;using UnityEngine;using System.Runtime.InteropServices;public class CallOC : MonoBehaviour{#if UNITY_IOS && !UNITY_EDITOR [DllImport("__Internal")] private static extern void test(); [DllImport("__Internal")] private static extern void testInt(int param); [DllImport("__Internal")] private static extern void testString(string param); [DllImport("__Internal")] private static extern bool testReturn(); [DllImport("__Internal")] private static extern string testReturnString();#endif // Start is called before the first frame update void Start() { Test(); TestInt(55); TestString("hello word"); bool b1 = TestReturn(); Debug.Log("TestReturn:"+b1); string s1 = TestReturnString(); Debug.Log("TestReturnString:"+s1); } // Update is called once per frame void Update() { } public void Test() {#if UNITY_IOS && !UNITY_EDITOR test();#endif } public void TestInt(int param) {#if UNITY_IOS && !UNITY_EDITOR testInt(param);#endif } public void TestString(string param) {#if UNITY_IOS && !UNITY_EDITOR testString(param);#endif } public bool TestReturn() {#if UNITY_IOS && !UNITY_EDITOR return testReturn();#endif return true; } public string TestReturnString() {#if UNITY_IOS && !UNITY_EDITOR return testReturnString();#endif return string.Empty; }}

二、OC调用C#

C# 代码
using System.Collections;using System.Collections.Generic;using UnityEngine;using System.Runtime.InteropServices;using System;public class CallUnity : MonoBehaviour{ [DllImport("__Internal")] public static extern void setCallback(IntPtr showPlayer); // Start is called before the first frame update void Start() { UFPCallback handler = new UFPCallback(Callback); IntPtr callbackDelegate = Marshal.GetFunctionPointerForDelegate(handler); SetCallback(callbackDelegate); } [UnmanagedFunctionPointer(CallingConvention.Cdecl)] public delegate void UFPCallback(); [AOT.MonoPInvokeCallback(typeof(UFPCallback))] static void Callback() { Debug.Log("OC 回调 C#"); } public void SetCallback(IntPtr showPlayer) { setCallback(showPlayer); }}
OC代码:
//// CallOC.m// UnityFramework//// Created by 飞杨 on 22.11.22.//#import "CallOC.h"typedef void (*CallUnity) ();#if defined (__cplusplus)extern "C"{#endif static CallUnity testCallUnityBlock; void setCallback(CallUnity showPlayer) { testCallUnityBlock = showPlayer; //模拟回调，不做任何处理。 if(testCallUnityBlock != nil) { testCallUnityBlock(); } } #if defined (__cplusplus)}#endif
