我想获取连接到我的 wifi 路由器的设备的 mac 地址、IP 地址、主机名、设备名称和品牌名称。我将获取除主机名之外的所有这些。

我已经尝试过 MMLAnscan、AFNetworking、LANScanMaster 等，它将为我提供除主机名之外的所有详细信息

+(NSString *)getHostFromIPAddress:(NSString*)ipAddress {
    struct addrinfo *result = NULL;
    struct addrinfo hints;

    memset(&hints, 0, sizeof(hints));
    hints.ai_flags = AI_NUMERICHOST;
    hints.ai_family = PF_UNSPEC;
    hints.ai_socktype = SOCK_STREAM;
    hints.ai_protocol = 0;

    //"www.kame.net", "http"
    int errorStatus = getaddrinfo([ipAddress cStringUsingEncoding:NSUTF8StringEncoding], NULL, &hints, &result);
    //NSUTF8StringEncoding instead of NSASCIIStringEncoding
    if (errorStatus != 0) {
        return nil;
    }

    CFDataRef addressRef = CFDataCreate(NULL, (UInt8 *)result->ai_addr, result->ai_addrlen);
    if (addressRef == nil) {
        return nil;
    }
    freeaddrinfo(result);

    CFHostRef hostRef = CFHostCreateWithAddress(kCFAllocatorDefault, addressRef);
    if (hostRef == nil) {
        return nil;
    }
    CFRelease(addressRef);

    BOOL succeeded = CFHostStartInfoResolution(hostRef, kCFHostNames, NULL);
    if (!succeeded) {
        return nil;
    }

    NSMutableArray *hostnames = [NSMutableArray array];

    CFArrayRef hostnamesRef = CFHostGetNames(hostRef, NULL);
    for (int currentIndex = 0; currentIndex < [(__bridge NSArray *)hostnamesRef count]; currentIndex++) {
        [hostnames addObject:[(__bridge NSArray *)hostnamesRef objectAtIndex:currentIndex]];
        NSLog(@"hostt:%@",hostnames);
    }
    NSLog(@"hostname:%@",hostnames[0]);
    return hostnames[0];
}

我想要连接到我的 wifi 的设备的主机名。
