網(wǎng)上大量的文章都采用下面的方法，但只能獲取到內(nèi)網(wǎng)IP
#import <ifaddrs.h>
#import <arpa/inet.h>
#import <net/if.h>
#define IOS_CELLULAR @"pdp_ip0"
#define IOS_WIFI @"en0"
#define IOS_VPN @"utun0"
#define IP_ADDR_IPv4 @"ipv4"
#define IP_ADDR_IPv6 @"ipv6"
#pragma mark - 獲取設(shè)備當(dāng)前網(wǎng)絡(luò)IP地址
+ (NSString *)getIPAddress:(BOOL)preferIPv4
{
NSArray *searchArray = preferIPv4 ?
@[ IOS_VPN @"/" IP_ADDR_IPv4, IOS_VPN @"/" IP_ADDR_IPv6, IOS_WIFI @"/" IP_ADDR_IPv4, IOS_WIFI @"/" IP_ADDR_IPv6, IOS_CELLULAR @"/" IP_ADDR_IPv4, IOS_CELLULAR @"/" IP_ADDR_IPv6 ] :
@[ IOS_VPN @"/" IP_ADDR_IPv6, IOS_VPN @"/" IP_ADDR_IPv4, IOS_WIFI @"/" IP_ADDR_IPv6, IOS_WIFI @"/" IP_ADDR_IPv4, IOS_CELLULAR @"/" IP_ADDR_IPv6, IOS_CELLULAR @"/" IP_ADDR_IPv4 ] ;
NSDictionary *addresses = [self getIPAddresses];
NSLog(@"addresses: %@", addresses);
__block NSString *address;
[searchArray enumerateObjectsUsingBlock:^(NSString *key, NSUInteger idx, BOOL *stop)
{
address = addresses[key];
//篩選出IP地址格式
if([self isValidatIP:address]) *stop = YES;
} ];
return address ? address : @"0.0.0.0";
}
想要獲取公網(wǎng)ip，可以采用下面的方法：
方法1:
NSError*error;
NSURL*ipURL = [NSURL URLWithString:@"http://ifconfig.me/ip"];
NSString*ip = [NSString stringWithContentsOfURL:ipURL encoding:NSUTF8StringEncodingerror:&error];
方法2:(個人推薦用這個請求，速度比較快)
NSError*error;
NSURL*ipURL = [NSURL URLWithString:@"http://ipof.in/txt"];
NSString*ip = [NSString stringWithContentsOfURL:ipURL encoding:NSUTF8StringEncodingerror:&error];
