NOTEAs of iOS7, you can no longer retrieve device MAC addresses. A fixed value will be returned rather than the actual MAC

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实际的 MAC

Somthing I stumbled across a while ago. Originally from hereI modified it a bit and cleaned things up.

不久前我偶然发现的东西。最初从这里我对其进行了一些修改并进行了清理。

IPAddress.h
IPAddress.c

IPAddress.h
IPAddress.c

And to use it

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]);
    }
}

Adapter names vary depending on the simulator/device as well as wifi or cell on the device.

适配器名称因模拟器/设备以及设备上的 wifi 或蜂窝而异。

Update:this will not work on iOS 7. You should use ASIdentifierManager.

更新：这不适用于 iOS 7。您应该使用ASIdentifierManager。

I wanted something to return the address regardless of whether or not wifi was enabled, so the chosen solution didn't work for me. I used another call I found on some forum after some tweaking. I ended up with the following (excuse my rusty C ) :

我想要一些东西来返回地址，无论是否启用了 wifi，所以选择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电话。我最终得到了以下结果（原谅我生疏的 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;
}

And then I would call it asking for en0, as follows:

然后我会称之为要求en0，如下所示：

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

Starting from iOS 7, the system always returns the value 02:00:00:00:00:00when you ask for the MAC address on any device.

从 iOS 7 开始，02:00:00:00:00:00当您在任何设备上询问 MAC 地址时，系统始终返回该值。

In iOS 7 and later, if you ask for the MAC address of an iOS device, the system returns the value 02:00:00:00:00:00. If you need to identify the device, use the identifierForVendor property of UIDevice instead. (Apps that need an identifier for their own advertising purposes should consider using the advertisingIdentifier property of ASIdentifierManager instead.)"

在 iOS 7 及更高版本中，如果您询问 iOS 设备的 MAC 地址，系统会返回值 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改用 ASIdentifierManager 的 AdvertisingIdentifier 属性。）”

Now iOS 7 devices – are always returning a MAC address of 02:00:00:00:00:00.

现在 iOS 7 设备 – 总是返回 02:00:00:00:00:00 的 MAC 地址。

So better use [UIDevice identifierForVendor].

所以最好使用 [UIDevice identifierForVendor]。

so better to call this method to get app specific unique key

所以最好调用这个方法来获取应用程序特定的唯一键

Category will more suitable

类别会更合适

import "UIDevice+Identifier.h"

导入“UIDevice+Identifier.h”

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

Now call above method to get unique address

现在调用上面的方法来获取唯一的地址

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

NSLog(@"%@",like_UDID);

It's not possible anymoreon devices running iOS 7.0 or later, thus unavailable to get MAC address in Swift.

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。

As Apple stated:

正如苹果所说：

In iOS 7 and later, if you ask for the MAC address of an iOS device, the system returns the value 02:00:00:00:00:00. If you need to identify the device, use the identifierForVendor property of UIDevice instead. (Apps that need an identifier for their own advertising purposes should consider using the advertisingIdentifier property of ASIdentifierManager instead.)

在 iOS 7 及更高版本中，如果您询问 iOS 设备的 MAC 地址，系统会返回值 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改用 ASIdentifierManager 的 AdvertisingIdentifier 属性。）

A lot of these questions only address the Mac address. If you also require the IP address I just wrote this, may need some work but seems to work well on my machine...
