如何以编程方式获取 iPhone 的 MAC 地址和 IP 地址？

Answer 1

注意 从 iOS7 开始，您无法再检索设备 MAC 地址。将返回一个固定值，而不是

我不久前偶然发现的实际 MAC Somthing。最初来自 此处 我修改了它稍微清理了一些东西。

IPAddress.h
IPAddress.c

并使用它

InitAddresses();
GetIPAddresses();
GetHWAddresses();

int i;
NSString *deviceIP = nil;
for (i=0; i<MAXADDRS; ++i)
{
    static unsigned long localHost = 0x7F000001;        // 127.0.0.1
    unsigned long theAddr;

    theAddr = ip_addrs[i];

    if (theAddr == 0) break;
    if (theAddr == localHost) continue;

    NSLog(@"Name: %s MAC: %s IP: %s\n", if_names[i], hw_addrs[i], ip_names[i]);

        //decided what adapter you want details for
    if (strncmp(if_names[i], "en", 2) == 0)
    {
        NSLog(@"Adapter en has a IP of %s", ip_names[i]);
    }
}

适配器名称根据模拟器/设备以及设备上的 wifi 或手机。

更新：这在 iOS 7 上不起作用。您应该使用 ASIdentifierManager.

Answer 3

我希望无论是否启用 wifi 都能返回地址，因此所选的解决方案对我不起作用。经过一些调整后，我使用了在某个论坛上找到的另一个调用。我最终得到以下结果（请原谅我生锈的 C ）：

#include <sys/types.h>
#include <stdio.h>
#include <string.h>
#include <sys/socket.h>
#include <net/if_dl.h>
#include <ifaddrs.h>


char*  getMacAddress(char* macAddress, char* ifName) {

int  success;
struct ifaddrs * addrs;
struct ifaddrs * cursor;
const struct sockaddr_dl * dlAddr;
const unsigned char* base;
int i;

success = getifaddrs(&addrs) == 0;
if (success) {
    cursor = addrs;
    while (cursor != 0) {
        if ( (cursor->ifa_addr->sa_family == AF_LINK)
            && (((const struct sockaddr_dl *) cursor->ifa_addr)->sdl_type == IFT_ETHER) && strcmp(ifName,  cursor->ifa_name)==0 ) {
            dlAddr = (const struct sockaddr_dl *) cursor->ifa_addr;
            base = (const unsigned char*) &dlAddr->sdl_data[dlAddr->sdl_nlen];
            strcpy(macAddress, ""); 
            for (i = 0; i < dlAddr->sdl_alen; i++) {
                if (i != 0) {
                    strcat(macAddress, ":");
                }
                char partialAddr[3];
                sprintf(partialAddr, "%02X", base[i]);
                strcat(macAddress, partialAddr);

            }
        }
        cursor = cursor->ifa_next;
    }

    freeifaddrs(addrs);
}    
return macAddress;
}

然后我会调用它来请求 en0，如下所示：

char* macAddressString= (char*)malloc(18);
NSString* macAddress= [[NSString alloc] initWithCString:getMacAddress(macAddressString, "en0")
                                              encoding:NSMacOSRomanStringEncoding];
free(macAddressString);

Answer 4

从 iOS 7 开始，当您在任何设备上请求 MAC 地址时，系统始终返回值 02:00:00:00:00:00。

在 iOS 7 及更高版本中，如果您询问 iOS 设备的 MAC 地址，系统将返回值 02:00:00:00:00:00。如果您需要识别设备，请改用 UIDevice 的identifierForVendor 属性。 （需要标识符用于自己的广告目的的应用程序应考虑使用 ASIdentifierManager 的 AdvertisingIdentifier 属性。）”

参考：发行说明

Answer 5

关于这个问题有多种解决方案，但我找不到完整的解决方案。
所以我为以下问题制定了自己的解决方案：

nicinfo

如何使用：

NICInfoSummary* summary = [[[NICInfoSummary alloc] init] autorelease];

// en0 is for WiFi 
NICInfo* wifi_info = [summary findNICInfo:@"en0"];

// you can get mac address in 'XX-XX-XX-XX-XX-XX' form
NSString* mac_address = [wifi_info getMacAddressWithSeparator:@"-"];

// ip can be multiple
if(wifi_info.nicIPInfos.count > 0)
{
    NICIPInfo* ip_info = [wifi_info.nicIPInfos objectAtIndex:0];
    NSString* ip = ip_info.ip;
    NSString* netmask = ip_info.netmask;
    NSString* broadcast_ip = ip_info.broadcastIP;
}
else
{
    NSLog(@"WiFi not connected!");
}

这看起来是一个非常干净的解决方案： UIDevice BIdentifier

// Return the local MAC addy
// Courtesy of FreeBSD hackers email list
// Accidentally munged during previous update. Fixed thanks to erica sadun & mlamb.
- (NSString *) macaddress{

    int                 mib[6];
    size_t              len;
    char                *buf;
    unsigned char       *ptr;
    struct if_msghdr    *ifm;
    struct sockaddr_dl  *sdl;

    mib[0] = CTL_NET;
    mib[1] = AF_ROUTE;
    mib[2] = 0;
    mib[3] = AF_LINK;
    mib[4] = NET_RT_IFLIST;

    if ((mib[5] = if_nametoindex("en0")) == 0) {
        printf("Error: if_nametoindex error\n");
        return NULL;
    }

    if (sysctl(mib, 6, NULL, &len, NULL, 0) < 0) {
        printf("Error: sysctl, take 1\n");
        return NULL;
    }

    if ((buf = malloc(len)) == NULL) {
        printf("Could not allocate memory. error!\n");
        return NULL;
    }

    if (sysctl(mib, 6, buf, &len, NULL, 0) < 0) {
        printf("Error: sysctl, take 2");
        free(buf);
        return NULL;
    }

    ifm = (struct if_msghdr *)buf;
    sdl = (struct sockaddr_dl *)(ifm + 1);
    ptr = (unsigned char *)LLADDR(sdl);
    NSString *outstring = [NSString stringWithFormat:@"%02X:%02X:%02X:%02X:%02X:%02X", 
                           *ptr, *(ptr+1), *(ptr+2), *(ptr+3), *(ptr+4), *(ptr+5)];
    free(buf);

    return outstring;
}

Answer 7

现在，iOS 7 设备 – 始终返回 MAC 地址 02:00:00:00:00:00。

所以最好使用[UIDeviceidentifierForVendor]。

所以最好调用此方法来获取应用程序特定的唯一键

类别将更适合

导入“UIDevice+Identifier.h”

- (NSString *) identifierForVendor1
{
    if ([[UIDevice currentDevice] respondsToSelector:@selector(identifierForVendor)]) {
        return [[[UIDevice currentDevice] identifierForVendor] UUIDString];
    }
    return @"";
}

现在调用上面的方法来获取唯一地址

NSString *like_UDID=[NSString stringWithFormat:@"%@",
                [[UIDevice currentDevice] identifierForVendor1]];

NSLog(@"%@",like_UDID);

Answer 9

在运行 iOS 7.0 或更高版本的设备上不再可能，因此无法在 Swift 中获取 MAC 地址。

正如苹果公司所说：

在 iOS 7 及更高版本中，如果您询问 iOS 设备的 MAC 地址，系统将返回值 02:00:00:00:00:00。如果您需要识别设备，请改用 UIDevice 的identifierForVendor 属性。 （需要标识符用于其自身广告目的的应用程序应考虑使用 ASIdentifierManager 的 AdvertisingIdentifier 属性。）

Answer 12

其中很多问题仅涉及 Mac 地址。如果您还需要我刚刚写的IP地址，可能需要一些工作，但似乎在我的机器上运行良好......

- (NSString *)getLocalIPAddress
{
    NSArray *ipAddresses = [[NSHost currentHost] addresses];
    NSArray *sortedIPAddresses = [ipAddresses sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];

    NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
    numberFormatter.allowsFloats = NO;

    for (NSString *potentialIPAddress in sortedIPAddresses)
    {
        if ([potentialIPAddress isEqualToString:@"127.0.0.1"]) {
            continue;
        }

        NSArray *ipParts = [potentialIPAddress componentsSeparatedByString:@"."];

        BOOL isMatch = YES;

        for (NSString *ipPart in ipParts) {
            if (![numberFormatter numberFromString:ipPart]) {
                isMatch = NO;
                break;
            }
        }
        if (isMatch) {
            return potentialIPAddress;
        }
    }

    // No IP found
    return @"?.?.?.?";
}
