How to get ip address from iOS

Use C Code

#import <ifaddrs.h>
#import <arpa/inet.h>

+ (NSString *)getIPAddress {
    
    NSString *address = @"";
    struct ifaddrs *interfaces = NULL;
    struct ifaddrs *temp_addr = NULL;
    
    if (getifaddrs(&interfaces) == 0) {
        temp_addr = interfaces;
        while (temp_addr != NULL) {
            if (temp_addr->ifa_addr->sa_family == AF_INET) {
                if ([[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"]) {
                    address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)];
                }
            }
            temp_addr = temp_addr->ifa_next;
        }
    }
    freeifaddrs(interfaces);
    return address;
}
