iOS获取路由器地址类似于192.168.1.1

最近做的项目需要获取路由器地址，查了很多资料以下方法终于成功了。
需要引用的头文件  

 
#include <sys/socket.h>
#import <netinet/in.h>
#import <netinet6/in6.h>
#import <arpa/inet.h>
#import <ifaddrs.h>
#include <netdb.h>
#import <SystemConfiguration/SCNetworkReachability.h> 
#import "getgateway.h"
#import <arpa/inet.h>

具体实现

- (NSString *) routerIp {
    
    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)
        /*/
         int i=255;
         while((i--)>0)
         //*/
        {
            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 //ifa_addr
                    //ifa->ifa_dstaddr is the broadcast address, which explains the "255's"
                    //                    address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_dstaddr)->sin_addr)];
                    
                    address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)];
                    
                    //routerIP----192.168.1.255 广播地址
                    NSLog(@"broadcast address--%@",[NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_dstaddr)->sin_addr)]);
                    //--192.168.1.106 本机地址
                    NSLog(@"local device ip--%@",[NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)]);
                    //--255.255.255.0 子网掩码地址
                    NSLog(@"netmask--%@",[NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_netmask)->sin_addr)]);
                    //--en0 端口地址
                    NSLog(@"interface--%@",[NSString stringWithUTF8String:temp_addr->ifa_name]);
                    
                }
                
            }
            
            temp_addr = temp_addr->ifa_next;
        }
    }
    
    // Free memory
    freeifaddrs(interfaces);
    
    
    
    in_addr_t i =inet_addr([address cStringUsingEncoding:NSUTF8StringEncoding]);
    in_addr_t* x =&i;
    
    
    unsigned char *s=getdefaultgateway(x);
    NSString *ip=[NSString stringWithFormat:@"%d.%d.%d.%d",s[0],s[1],s[2],s[3]];
    
    NSLog(@"路由器地址-----%@",ip);
    return ip;
}
