Ios 正在Obj中查找IPV6地址。C iphone

我目前正在编写一个unity插件，允许我使用Game Center与Mirror进行配对

为此，我需要找到主机的IPV6以将其发送给其他播放器，但是，我无法找到一种简单的方法在obj C中实现这一点

在升级我的IPV6代码之前，这是我用来获取IPV4的代码：

+ (NSString *)GetInternalIpAddress
{
    NSString *address = @"error";
    struct ifaddrs *interfaces = NULL;
    struct ifaddrs *temp_addr = NULL;
    int success = 0;
    // retrieve the current interfaces - returns 0 on success
    success = getifaddrs(&interfaces);
    if (success == 0) {
        // Loop through linked list of interfaces
        temp_addr = interfaces;
        while(temp_addr != NULL) {
            if(temp_addr->ifa_addr->sa_family == AF_INET) {
                // Check if interface is en0 which is the wifi connection on the iPhone
                if([[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"]) {
                    // Get NSString from C String
                    address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)];
                }
            }
            temp_addr = temp_addr->ifa_next;
        }
    }
    // Free memory
    freeifaddrs(interfaces);
    return address;
}

任何帮助都将不胜感激

以下是我最终使用的：

+(NSString *)GetIP
{
    struct ifaddrs *ifa, *ifa_tmp;
    char addr[INET6_ADDRSTRLEN];

    if (getifaddrs(&ifa) == -1) {
        perror("getifaddrs failed");
        exit(1);
    }

    ifa_tmp = ifa;
    while (ifa_tmp) {
        if ((ifa_tmp->ifa_addr) && ((ifa_tmp->ifa_addr->sa_family == AF_INET) ||
                                  (ifa_tmp->ifa_addr->sa_family == AF_INET6))) {
            if (ifa_tmp->ifa_addr->sa_family == AF_INET) {
                // create IPv4 string
                struct sockaddr_in *in = (struct sockaddr_in*) ifa_tmp->ifa_addr;
                inet_ntop(AF_INET, &in->sin_addr, addr, sizeof(addr));
            } else { // AF_INET6
                // create IPv6 string
                struct sockaddr_in6 *in6 = (struct sockaddr_in6*) ifa_tmp->ifa_addr;
                inet_ntop(AF_INET6, &in6->sin6_addr, addr, sizeof(addr));
                if([[NSString stringWithUTF8String:ifa_tmp->ifa_name]  isEqual: @"en0"] && ![[NSString stringWithUTF8String:addr] containsString:@"::"])
                {
                    printf("name = %s\n", ifa_tmp->ifa_name);
                    printf("addr = %s\n", addr);

                    return([NSString stringWithUTF8String:addr]);
                }
            }
        }
        ifa_tmp = ifa_tmp->ifa_next;
    }
    freeifaddrs(ifa);
    return nil;
}
