獲取iOS裝置當前ip位址

第一種方法是用系統api的方式獲取，如下

#include

//#include "getaddresses.h" 
#define min(a,b) ((a) < (b) ? (a) : (b)) 
#define max(a,b) ((a) > (b) ? (a) : (b)) 
#define buffersize 4000 
char *if_names[maxaddrs]; 
char *ip_names[maxaddrs]; 
char *hw_addrs[maxaddrs]; 
unsigned long ip_addrs[maxaddrs]; 
static int nextaddr = 0; 
void initaddresses() 
if ((cptr = (char *)strchr(ifr->ifr_name, ':')) != null) 
if (strncmp(lastname, ifr->ifr_name, ifnamsiz) == 0) 
memcpy(lastname, ifr->ifr_name, ifnamsiz); 
ifrcopy = *ifr; 
ioctl(sockfd, siocgifflags, &ifrcopy); 
flags = ifrcopy.ifr_flags; 
if ((flags & iff_up) == 0) 
if_names[nextaddr] = (char *)malloc(strlen(ifr->ifr_name)+1); 
if (if_names[nextaddr] == null) 
strcpy(if_names[nextaddr], ifr->ifr_name); 
sin = (struct sockaddr_in *)&ifr->ifr_addr; 
strcpy(temp, inet_ntoa(sin->sin_addr)); 
ip_names[nextaddr] = (char *)malloc(strlen(temp)+1); 
if (ip_names[nextaddr] == null) 
strcpy(ip_names[nextaddr], temp); 
ip_addrs[nextaddr] = sin->sin_addr.s_addr; 
++nextaddr; 
} close(sockfd); 
} void gethwaddresses() 
} } } 
cp += sizeof(ifr->ifr_name) + max(sizeof(ifr->ifr_addr), ifr->ifr_addr.sa_len); 
} close(sockfd); 
} - (nsstring *)deviceipadress

這樣得到的ip，如果在內網中，那麼就是內網的ip.

第二種方法是可以獲取公網ip

- (void)getcurrentip  

; }]; 
[request setfailedblock:^]; 
}

用到了asihttprequest這個網路開源庫。

這個http url就可以獲取你當前的ip位址。
