因為項目中加入的第三方數(shù)據(jù)統(tǒng)計SDK中需要上傳IP地址滨溉,之前沒有接觸過IP地址上傳什湘,于是搜索了iOS中獲取設(shè)備ip地址的相關(guān)資料并加以整理形成本文。
獲取IP地址主要有以下兩種情況:
WIFI情況下獲取內(nèi)網(wǎng)IP地址:
// 需導(dǎo)入以下頭文件
#import <ifaddrs.h>
#import <arpa/inet.h>
// Get IP Address
- (NSString *)GetOurIpAddress {
NSString *address = @"error";
struct ifaddrs *interfaces = NULL;
struct ifaddrs *temp_addr = NULL;
int success = 0;
// retrieve the current interfaces - returns 0 on success
success = getifaddrs(&interfaces);
if (success == 0) {
// Loop through linked list of interfaces
temp_addr = interfaces;
while(temp_addr != NULL) {
if(temp_addr->ifa_addr->sa_family == AF_INET) {
// Check if interface is en0 which is the wifi connection on the iPhone
if([[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"]) {
// Get NSString from C String
address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)];
}
}
temp_addr = temp_addr->ifa_next;
}
}
// Free memory
freeifaddrs(interfaces);
return address;
}
WIFI情況下獲取外網(wǎng)IP地址 與 數(shù)據(jù)流量情況下獲取手機IP地址
上述兩種情況(WIFI下外網(wǎng)IP與數(shù)據(jù)下手機IP)皆可用下述代碼獲取IP
通過訪問搜狐的citySN獲取IP信息
-(NSDictionary *)deviceWANIPAdress{
NSError *error;
NSURL *ipURL = [NSURL URLWithString:@"http://pv.sohu.com/cityjson?ie=utf-8"];
NSMutableString *ip = [NSMutableString stringWithContentsOfURL:ipURL encoding:NSUTF8StringEncoding error:&error];
//判斷返回字符串是否為所需數(shù)據(jù)
if ([ip hasPrefix:@"var returnCitySN = "]) {
//對字符串進(jìn)行處理晦攒,然后進(jìn)行json解析
//刪除字符串多余字符串
NSRange range = NSMakeRange(0, 19);
[ip deleteCharactersInRange:range];
NSString * nowIp =[ip substringToIndex:ip.length-1];
//將字符串轉(zhuǎn)換成二進(jìn)制進(jìn)行Json解析
NSData * data = [nowIp dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary * dict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
return dict;
}
return nil;
}
通過上面方法會返回一個包含IP信息的字典闽撤,信息內(nèi)容如下:
{
// 郵政編碼
cid = 350200;
// IP
cip = "211.97.130.169";
// 地理信息
cname = "\U798f\U5efa\U7701\U53a6\U95e8\U5e02";
}
Tips:
- WIFI情況下獲取到的IP地址中的cname,一般情況下只有精確到省份脯颜,而數(shù)據(jù)流量情況下能精確到市
- 上述兩種情況下獲取到的郵政編碼一致哟旗。
- cname中的內(nèi)容以Unicode編碼的形式返回,如需使用還需處理
通過淘寶的getIpInfo服務(wù)獲取IP
-(NSDictionary *)deviceWANIPAdress{
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];
return ipDic;
}
通過上面方法會返回一個包含IP信息的字典栋操,信息內(nèi)容如下:
{
area = "";
"area_id" = "";
city = "\U53a6\U95e8";
"city_id" = 350200;
country = "\U4e2d\U56fd";
"country_id" = CN;
county = XX;
"county_id" = xx;
ip = "183.250.89.75";
isp = "\U79fb\U52a8";
"isp_id" = 100025;
region = "\U798f\U5efa";
"region_id" = 350000;
}
相比之下闸餐,淘寶的IP信息返回多了些信息,如運營商等矾芙。其余并無太大差別舍沙,根據(jù)自己的需求任意選擇即可
