以前做過獲取設(shè)備IP地址的功能巍沙，但是由于當(dāng)時(shí)代碼管理不當(dāng)犯祠，很多代碼已經(jīng)遺失，現(xiàn)在只能重新過一遍窖铡，也讓自己更有基情激情的學(xué)習(xí)疗锐。網(wǎng)上關(guān)于這方面的文章很多，但是找到自己真正需要的卻不容易费彼，經(jīng)過幾番周折窒悔。終于在著名的stackoverflow上面找到了我想要的答案。
代碼如下：(最新代碼敌买，請(qǐng)往下翻)

很多朋友說(shuō)這個(gè)方法只能獲取到內(nèi)網(wǎng)IP简珠，無(wú)法獲取公網(wǎng)IP，確實(shí)虹钮，這邊補(bǔ)充下獲取公網(wǎng)IP方式聋庵。(由于訪問網(wǎng)絡(luò)緩慢，最新做法請(qǐng)往下翻)
//方法一：
NSError *error;
NSURL *ipURL = [NSURL URLWithString:@"http://ifconfig.me/ip"];
NSString *ip = [NSString stringWithContentsOfURL:ipURL encoding:NSUTF8StringEncoding error:&error];
//方法二：個(gè)人推薦用這個(gè)請(qǐng)求芙粱，速度比較快
/*
http://ipof.in/json
http://ipof.in/xml
http://ipof.in/txt
If you want HTTPS you can use the same URLs with https prefix. The advantage being that even if you are on a Wifi you will get the public address.
*/
NSError *error;
NSURL *ipURL = [NSURL URLWithString:@"http://ipof.in/txt"];

增加部分公開API
1祭玉、淘寶API
1. 請(qǐng)求接口（GET）：
查詢某ip信息：http://ip.taobao.com/service/getIpInfo.php?ip=ip地址
查詢自己的ip信息：http://ip.taobao.com/service/getIpInfo.php?ip=myip
2. 響應(yīng)信息：
（json格式的）國(guó)家 、蚀号稀（自治區(qū)或直轄市）脱货、市（縣）、運(yùn)營(yíng)商
3. 返回?cái)?shù)據(jù)格式：
{
"code": 0,
"data": {
"country": "中國(guó)",
"country_id": "CN",
"area": "華南",
"area_id": "800000",
"region": "廣東省",
"region_id": "440000",
"city": "深圳市",
"city_id": "440300",
"county": "",
"county_id": "-1",
"isp": "電信",
"isp_id": "100017",
"ip": "121.35.211.41"
}
}
其中code的值的含義為律姨，0：成功振峻，1：失敗。
4. 訪問限制：為了保障服務(wù)正常運(yùn)行择份，每個(gè)用戶的訪問頻率需小于10qps扣孟。
| 參數(shù)名 | 含義 |
|---|---|
| code | 狀態(tài)碼，正常為0荣赶，異常的時(shí)候?yàn)榉?凤价。 |
| data | 查詢到的結(jié)果鸽斟。 |
| country | 國(guó)家。 |
| country_id | 國(guó)家代碼利诺。 |
| area | 地區(qū)名稱（華南富蓄、華北...）。 |
| area_id | 地區(qū)編號(hào)慢逾。 |
| region | 省名稱格粪。 |
| region_id | 省編號(hào)。 |
| city | 市名稱氛改。 |
| city_id | 市編號(hào)。 |
| county | 縣名稱比伏。 |

| isp | ISP服務(wù)商名稱（電信/聯(lián)通/鐵通/移動(dòng)...）。 |
| isp_id | ISP服務(wù)商編號(hào)赁项。 |
| ip | 查詢的IP地址葛躏。 |
2、站長(zhǎng)工具API
