title: Unique Identification of iOS device
body: <p>I was using Mac address for unique identification of the iOS device, but from iOS7 the system always returns 02:00:00:00:00:00 value. I had searched three options for the mentioned issue: </p>
  
  <ol>
  <li>Vendor identification</li>
  <li>Advertising identification</li>
  <li>Getting serial number using IOUnit framework</li>
  </ol>
  
  <p>Since the IOUnitFramework is not approved by appstore, cant use it in my application. And the vendor identification and advertising identification return very long values.</p>
  
  <p>Is there any other possible way to uniquely identify the ios device?</p>
  
  <p>Thanks in advance</p>
  
  <p>Storing a unique identifier in keychain is another option. But we can't access the keychain directly from our ios device.So is there any other alternative way for unique identification of the device?</p>
