iOS 获取手机当前所连接的网络的IP地址

1首先要在当前所在的类导入这几个头文件：

#include

#include

#include

#include

#import

2具体代码的实现：

//获取手机的网络的ip地址

- (NSString *)getIPAddress

{

BOOL success;

struct ifaddrs * addrs;

const struct ifaddrs * cursor;

success = getifaddrs(&addrs) == 0;

if (success) {

cursor = addrs;

while (cursor != NULL) {

// the second test keeps from picking up the loopback address

if (cursor->ifa_addr->sa_family == AF_INET && (cursor->ifa_flags & IFF_LOOPBACK) == 0)

{

NSString *name = [NSString stringWithUTF8String:cursor->ifa_name];

if ([name isEqualToString:@"en0"]) // Wi-Fi adapter

NSLog(@"IP:%@",[NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)cursor->ifa_addr)->sin_addr)]);

return [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)cursor->ifa_addr)->sin_addr)];

}

cursor = cursor->ifa_next;

}

freeifaddrs(addrs);

}

return nil;

}

NSLog(@"========11========%@",[self getIPAddress]);
