iOS 获取IP地址方法

闲来无事做个东西要获取iPhone的ip地址，网上好多方法没法用，这有一个能用的，记录下来。

代码块

引入文件#import <ifaddrs.h>#import <arpa/inet.h>获取ip地址-(void)getIPaddress{NSString *address = @"error";struct ifaddrs * ifaddress = NULL;struct ifaddrs * temp_address = NULL;int success = 0;success = getifaddrs(&ifaddress);if(success == 0) {temp_address = ifaddress;while(temp_address != NULL) {if(temp_address->ifa_addr->sa_family == AF_INET) { if([[NSString stringWithUTF8String:temp_address->ifa_name] isEqualToString:@"en0"]) {address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_address->ifa_addr)->sin_addr)];}}temp_address = temp_address->ifa_next;}}NSLog(@"获取到的IP地址为：%@",address);}
