iOS Get the address code of mobile phone ip

In this paper, we share the specific code of iOS to obtain the address of mobile phone ip for your reference. The specific contents are as follows

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

// Get IP Address
- (NSString *)getIPAddress {
  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;
}
