NSURL *ipURL = [NSURL URLWithString:@"http://ip.taobao.com/service/getIpInfo2.php?ip=myip"];
NSData *data = [NSData dataWithContentsOfURL:ipURL];
NSDictionary *ipDic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
NSString *ipStr = nil;
if (ipDic && [ipDic[@"code"] integerValue] == 0) {
ipStr = ipDic[@"data"][@"ip"];
}
第二种方法
NSError *error;
NSURL *ipURL = [NSURL URLWithString:@"http://ifconfig.me/ip"];
NSString *ip = [NSString stringWithContentsOfURL:ipURL encoding:NSUTF8StringEncoding error:&error];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:ip forKey:@"netWorkIP"];
