本文介绍了使用CFMessagePort进行进程间通信的实现方法，包括发送请求及接收响应的过程，并提供了具体的代码示例。

// 下面是进程A发送请求，返回

CFDataRef returnData = NULL;
            CFMessagePortRef remote = CFMessagePortCreateRemote(kCFAllocatorDefault, (CFStringRef)STATIC_COFIG_MESSAGE_PORT);
            NSLog(@"\n\n mobile phone 2");
            int iResult = CFMessagePortSendRequest(remote, 0, NULL, 5.0, 5.0, kCFRunLoopDefaultMode, &returnData);
            NSLog(@"\n\nCFMessagePortSendRequest Result: %d", iResult);
            
            CFPropertyListFormat format;
            CFPropertyListRef dicRef = CFPropertyListCreateWithData(NULL, returnData, kCFPropertyListImmutable, &format, NULL);
            
            
            m_Config = [[NSDictionary alloc] initWithDictionary:(NSDictionary *)dicRef];

// 下面是进程B接收代码

CFMessagePortRef local2 = CFMessagePortCreateLocal(NULL,
                                                              (CFStringRef)STATIC_COFIG_MESSAGE_PORT,
                                                              returnConfigDic, NULL, NULL);
            CFRunLoopSourceRef source2 = CFMessagePortCreateRunLoopSource(NULL, local2, 0);
            CFRunLoopAddSource(CFRunLoopGetCurrent(), source2, kCFRunLoopDefaultMode);

// 回调

CFDataRef returnConfigDic(CFMessagePortRef local, SInt32 msgid, CFDataRef data, void *info)
{
    NSLog(@"\n\n returnConfigDic 1");
    if (m_Config != nil) {
        NSLog(@"\n\n returnConfigDic 2");
        NSLog(@"\n\n returnConfigDic m_Config: %@", m_Config);
        CFDataRef configDataRef = CFPropertyListCreateData(NULL, (CFPropertyListRef)m_Config, kCFPropertyListXMLFormat_v1_0, kCFPropertyListImmutable, NULL);
        return configDataRef;
    } else {
        NSDictionary *nilDic = [[NSDictionary alloc] initWithObjects:@[@"0"] forKeys:@[STATIC_MESSAGE_TELEPHONE_NUMBER]];
        CFDataRef nilConfigDataRef = CFPropertyListCreateData(NULL, (CFPropertyListRef)nilDic, kCFPropertyListXMLFormat_v1_0, kCFPropertyListImmutable, NULL);
        return nilConfigDataRef;
    }

}

可能存在些内存泄露问题~~ 初学者，见谅 & 欢迎提宝贵意见
