我怎么可以编程方式获得MAC地址的iphone

Question

如何编程方式获得的iPhone的MAC地址和IP地址吗？

Answer 1

注意如图iOS7，可以不再检索设备的MAC地址。固定值将被返回，而不是实际MAC

财产以后我跨越一段时间以前绊倒。最初从这里我修改有点和清理东西。

IPAddress.h 结果 IPAddress.c

和使用它

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]);
    }
}

适配器名称取决于模拟器/设备上以及在设备上的Wi-Fi或细胞

更新： 这在 iOS 7 上不起作用。你应该使用 AS标识符管理器.

我想要的东西，无论是否无线网络的返回地址被启用，所以选择的解决方案并没有为我工作。我用另一个电话我在做一些调整后，一些论坛中。我结束了以下（原谅我生锈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;
}

然后我将称之为要求的 EN0 下，如下所示：

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

Answer 4

从iOS7，系统总是返回的价值 02:00:00:00:00:00 当你问MAC地址上的任何设备。

在iOS7及以后，如果你问的MAC地址iOS设备、系统的回报的价值02:00:00:00:00:00.如果你需要识别设备，使用的identifierForVendor财产的UIDevice代替。(应用程序，需要一个标识符为他们自己的广告目的，应考虑使用advertisingIdentifier财产的ASIdentifierManager代替。)"

参考： 发行说明

Answer 5

有改变这个解决方案，但我无法找到一个整体的东西。 所以我做了我自己的解决方案：

nicinfo

使用方法：

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!");
}

这看起来像一个漂亮整洁的解决方案： 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

现在的iOS 7设备 - 总是返回的MAC地址02：00：00：00：00：00

。

因此，更好地使用[的UIDevice identifierForVendor]。

所以最好调用此方法来获取应用程序专用的唯一关键

类别将更加适合

导入 “的UIDevice + Identifier.h”

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

现在调用上述方法来获得唯一的地址

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

NSLog(@"%@",like_UDID);

Answer 9

<强>这是不可能的了在运行iOS 7.0设备或更高，从而无法在夫特得到MAC地址。

如苹果公司表示：

  

在的iOS 7和后，如果要求一个iOS设备的MAC地址，则系统返回值02：00：00：00：00：00。如果您需要识别设备，使用的UIDevice的identifierForVendor属性。 （需要对他们自己的广告目的的标识符的应用程序应考虑使用ASIdentifierManager的advertisingIdentifier属性。）

要基于在IOS 6装置的唯一标识符创建一个uniqueString：

NSString *uniqueString = [[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString];
NSLog(@"uniqueString: %@", uniqueString);

很多这些问题只有地址的MAC地址。如果你还需要我刚才写的IP地址，可能需要一些工作，但似乎我的机器上很好地工作...

- (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 @"?.?.?.?";
}
