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/"

res_state res = (res_state)malloc(sizeof(struct __res_state));
__uint32_t dwDNSIP = ;
int result = res_ninit(res);
if (result == ) {
dwDNSIP = res->nsaddr_list[].sin_addr.s_addr;
}
free(res);
NSString *dns = [NSString stringWithUTF8String:inet_ntoa(res->nsaddr_list[].sin_addr)];

return tmp;

if (result == TRUE) {

}
