需要引入的库有
#import <SystemConfiguration/CaptiveNetwork.h>
#import <ifaddrs.h>
#import <arpa/inet.h>
1 获取Wi-Fi信息，代码如下：
- (NSDictionary *)getIphoneMessage{
NSDictionary *info = nil;
NSArray *ifs = (__bridge_transfer NSArray *)CNCopySupportedInterfaces();
if (!ifs) {
return nil;
}
for (NSString *ifnam in ifs) {
info = (__bridge_transfer NSDictionary *)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);
if (info && [info count]) {
break;
}
}
return info;
}
2 获取设备网关信息，代码如下：
- (NSString *)getIPAddressForCurrentWiFi{
NSString *address = nil;
struct ifaddrs *interfaces = NULL;
struct ifaddrs *temp_addr = NULL;
int success = 0;
success = getifaddrs(&interfaces);
if (success == 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)];
// 广播地址
NSLog(@"broadcast address--%@",[NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_dstaddr)->sin_addr)]);
// 本地IP地址
NSLog(@"local device ip--%@",[NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)]);
//子网掩码地址
NSLog(@"netmask--%@",[NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_netmask)->sin_addr)]);
// 端口地址
NSLog(@"interface--%@",[NSString stringWithUTF8String:temp_addr->ifa_name]);
}
}
temp_addr = temp_addr->ifa_next;
}
}
freeifaddrs(interfaces);
return address;
}
打印结果如下：
2017-07-10 11:26:20.450 GetIphoneDeviceDetailDemo[4784:66867] broadcast address--10.40.131.255
2017-07-10 11:26:20.450 GetIphoneDeviceDetailDemo[4784:66867] local device ip--10.40.131.230
2017-07-10 11:26:20.451 GetIphoneDeviceDetailDemo[4784:66867] netmask--255.255.254.0
2017-07-10 11:26:20.451 GetIphoneDeviceDetailDemo[4784:66867] interface--en0
