ios 设备基本信息检测

开发ios确实会让人身心愉悦（相对于deskop，android），ios app更多的让人集中注意力到它本身的体验，性能。这非常好，我非常喜欢相对完美的事物。

最近遇到一些乱七八糟的需求。需要获取一些设备信息，网络情况。iOS 上开发非常简单有趣，除了一些乱七八糟的信息，例如：摄像头硬件信息，本地相册初始化时间（第一次拍照保存），等。

剩下一些信息就是我要的了：

还是代码演示：

#define IOS_CELLULAR    @"pdp_ip0"
#define IOS_WIFI        @"en0"
#define IP_ADDR_IPv4    @"ipv4"
#define IP_ADDR_IPv6    @"ipv6"
#define ADDRESSIP   @"http://www.cz88.net/ip/viewip778.aspx"
#define ADDRESSIPWY @"http://nstool.netease.com/"

//获取本地的DNS IP
+ (NSDictionary *)getDNSIp {
    res_state res = (res_state)malloc(sizeof(struct __res_state));
    __uint32_t dwDNSIP = 0;
    int result = res_ninit(res);
    if (result == 0) {
        dwDNSIP = res->nsaddr_list[0].sin_addr.s_addr;
    }
    free(res);
    NSString *dns = [NSString stringWithUTF8String:inet_ntoa(res->nsaddr_list[0].sin_addr)];
    NSDictionary *tmp = [[NSDictionary alloc] initWithObjectsAndKeys: dns, @"LocalDNS", nil];
    return tmp;
}

//获取制定域名的IP地址
+ (NSDictionary *)ServersToIp:(NSString *)ip {
    Boolean result;
    CFHostRef hostRef;
    CFArrayRef addresses=nil;
    NSString *hostname = ip;
    NSMutableArray *array = [[NSMutableArray alloc] init];
    hostRef = CFHostCreateWithName(kCFAllocatorDefault, (__bridge CFStringRef)hostname);
    if (hostRef) {
        result = CFHostStartInfoResolution(hostRef, kCFHostAddresses, NULL); // pass an error instead of NULL here to find out why it failed
        if (result == TRUE) {
            addresses =  CFHostGetAddressing(hostRef, &result);
        }
    }
    if (result == TRUE) {
        NSMutableArray *tempDNS = [[NSMutableArray alloc] init];
        for(int i = 0; i < CFArrayGetCount(addresses); i++){
            struct sockaddr_in* remoteAddr;
            CFDataRef saData = (CFDataRef)CFArrayGetValueAtIndex(addresses, i);
            remoteAddr = (struct sockaddr_in*)CFDataGetBytePtr(saData);
            
            if(remoteAddr != NULL){
                // Extract the ip address
                //const char *strIP41 = inet_ntoa(remoteAddr->sin_addr);
                NSString *strDNS =[NSString stringWithCString:inet_ntoa(remoteAddr->sin_addr) encoding:NSASCIIStringEncoding];
                [array addObject:strDNS];
                [tempDNS addObject:strDNS];
            }
        }
    } else {
        NSLog(@"Not resolved");
    }
    return [NSDictionary dictionaryWithObjectsAndKeys: array, ip, nil];
}
