1 | # iOSGetMACAddress
2 | iOS another way to get mac address after iOS 7.
3 |
4 | ## Why
5 | Since iOS 7.0, you cannot easily using ```sysctl()``` or ```ioctl()``` to get MAC address(normal way).
6 |
7 |
8 | [Link (the most bottom)](https://developer.apple.com/library/content/releasenotes/General/WhatsNewIniOS/Articles/iOS7.html)
9 |
10 | ```
11 | 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.
12 | If you need to identify the device, use the identifierForVendor property of UIDevice instead.
13 | (Apps that need an identifier for their own advertising purposes should consider using the advertisingIdentifier property of ASIdentifierManager instead.)
14 | ```
15 |
16 | ## Way1: iOS version is less than or equal to 10.1
17 | 1. Connect to any Wi-Fi.
18 | 2. Get current IP address of Wi-Fi.
19 | 1. Send ICMP echo request(ping) to the IP address.(not the IP address, 127.0.0.1)
20 | 2. Walk whole ARP table to search the MAC address of current IP address of Wi-Fi.
21 | 3. Get your MAC address.
22 |
23 | ## Way2: iOS version is less than or equal to 10.2.1
24 | 1. Connect to any Wi-Fi.
25 | 2. Get current IP address of Wi-Fi.
26 | 1. Send ICMP echo request(ping) to the IP address.(not the IP address, 127.0.0.1)
27 | 2. Get an ARP entry by current IP address of Wi-Fi.
28 | 3. Get your MAC address.
29 |
30 | ## Way3: iOS version is greater than 10.1(or lesser version)
31 | 1. Connect to any Wi-Fi.
32 | 2. Get current IP address of Wi-Fi.
33 | 1. Send MDNS query that question "\_apple-mobdev2.\_tcp.local" with PTR record.
34 | 2. Response data will content MAC address.
35 | 3. Get your MAC address.
36 |
37 | ## Result
38 | Include 2 different iOS version.
