本文執行個體為大家分享了iOS擷取手機ip地址的具體代碼，供大家參考，具體內容如下

#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;}
