iOS获取手机的IP地址

来源：互联网发布：淘宝新店如何刷单编辑：程序博客网时间：2024/06/06 09:03

1.添加这五个库（在联网的情况下）

#import <sys/socket.h>#import <sys/sockio.h>#import <sys/ioctl.h>#import <net/if.h>#import <arpa/inet.h>

2.写一个方法

- (NSString *)getDeviceIPIpAddresses{    int sockfd =socket(AF_INET,SOCK_DGRAM, 0);//    if (sockfd <</span> 0) return nil;    NSMutableArray *ips = [NSMutableArrayarray];    int BUFFERSIZE =4096;    structifconf ifc;    char buffer[BUFFERSIZE], *ptr, lastname[IFNAMSIZ], *cptr;    structifreq *ifr, ifrcopy;        ifc.ifc_len = BUFFERSIZE;    ifc.ifc_buf = buffer;        if (ioctl(sockfd,SIOCGIFCONF, &ifc) >= 0){        for (ptr = buffer; ptr < buffer + ifc.ifc_len; ){            ifr = (structifreq *)ptr;            int len =sizeof(structsockaddr);            if (ifr->ifr_addr.sa_len > len) {                len = ifr->ifr_addr.sa_len;            }            ptr += sizeof(ifr->ifr_name) + len;            if (ifr->ifr_addr.sa_family !=AF_INET) continue;                        if ((cptr = (char *)strchr(ifr->ifr_name,':')) != NULL) *cptr =0;                        if (strncmp(lastname, ifr->ifr_name,IFNAMSIZ) == 0)continue;                        memcpy(lastname, ifr->ifr_name,IFNAMSIZ);                        ifrcopy = *ifr;            ioctl(sockfd,SIOCGIFFLAGS, &ifrcopy);                        if ((ifrcopy.ifr_flags &IFF_UP) == 0)continue;                        NSString *ip = [NSString stringWithFormat:@"%s",inet_ntoa(((structsockaddr_in *)&ifr->ifr_addr)->sin_addr)];            [ips addObject:ip];        }    }    close(sockfd);        NSString *deviceIP =@"";    for (int i=0; i < ips.count; i++)    {        if (ips.count >0)        {            deviceIP = [NSStringstringWithFormat:@"%@",ips.lastObject];            }    }    NSLog(@"deviceIP========%@",deviceIP);    return deviceIP;}

stackoverflow上找到一种方法，能实时获取IP

第三种方法
