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

#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()  } 

void freeaddresses() 

initaddresses(); 

} void getipaddresses() 

sockfd = socket(af_inet, sock_dgram, 0); 

if (sockfd < 0) 

ifc.ifc_len = buffersize; 

ifc.ifc_buf = buffer; 

if (ioctl(sockfd, siocgifconf, &ifc) < 0) 

lastname[0] = 0; 

for (ptr = buffer; ptr < buffer + ifc.ifc_len; ) 

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() 

sockfd = socket(af_inet, sock_dgram, 0); 

if (sockfd < 0) 

ifc.ifc_len = buffersize; 

ifc.ifc_buf = buffer; 

if (ioctl(sockfd, siocgifconf, (char *)&ifc) < 0) 

ifr = ifc.ifc_req; 

cplim = buffer + ifc.ifc_len; 

for (cp=buffer; cp < cplim; ) 

} www.2cto.com

} } 

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。
