How can I programmatically get the MAC address of an iphone

Question

How to programmatically get an iPhone s MAC address and IP address

User · Answer

It s not possible anymore on devices running iOS 7 0 or later  thus unavailable to get MAC address in Swift   As Apple stated      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

Update  this will not work on iOS 7  You should use ASIdentifierManager     More clean solution on MobileDeveloperTips website    include  lt sys socket h gt   include  lt sys sysctl h gt   include  lt net if h gt   include  lt net if dl h gt        -  NSString   getMacAddress     int                 mgmtInfoBase 6     char                 msgBuffer   NULL    size t              length    unsigned char       macAddress 6     struct if msghdr     interfaceMsgStruct    struct sockaddr dl   socketStruct    NSString             errorFlag   NULL        Setup the management Information Base  mib    mgmtInfoBase 0    CTL NET            Request network subsystem   mgmtInfoBase 1    AF ROUTE           Routing table info   mgmtInfoBase 2    0                  mgmtInfoBase 3    AF LINK            Request link layer information   mgmtInfoBase 4    NET RT IFLIST      Request all configured interfaces       With all configured interfaces requested  get handle index   if   mgmtInfoBase 5    if nametoindex  en0       0       errorFlag     if nametoindex failure     else            Get the size of the data available  store in len      if  sysctl mgmtInfoBase  6  NULL   amp length  NULL  0   lt  0         errorFlag     sysctl mgmtInfoBase failure       else                Alloc memory based on above call       if   msgBuffer   malloc length      NULL          errorFlag     buffer allocation failure         else                    Get system information  store in buffer         if  sysctl mgmtInfoBase  6  msgBuffer   amp length  NULL  0   lt  0            errorFlag     sysctl msgBuffer failure                           Befor going any further      if  errorFlag    NULL          NSLog   Error       errorFlag       return errorFlag            Map msgbuffer to interface message structure   interfaceMsgStruct    struct if msghdr    msgBuffer        Map to link-level socket structure   socketStruct    struct sockaddr dl     interfaceMsgStruct   1         Copy link layer address data in socket structure to an array   memcpy  amp macAddress  socketStruct- gt sdl data   socketStruct- gt sdl nlen  6         Read from char array into a string object  into traditional Mac address format   NSString  macAddressString    NSString stringWithFormat    02X  02X  02X  02X  02X  02X                                    macAddress 0   macAddress 1   macAddress 2                                    macAddress 3   macAddress 4   macAddress 5      NSLog   Mac Address       macAddressString         Release the buffer memory   free msgBuffer      return macAddressString

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

Now iOS 7 devices     are always returning a MAC address of 02 00 00 00 00 00   So better use  UIDevice identifierForVendor    so better to call this method to get app specific unique key  Category will more suitable  import  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  NSString  like UDID  NSString stringWithFormat                          UIDevice currentDevice  identifierForVendor1     NSLog       like UDID

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     -  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
