title: Access all (user) accounts inside Keychain
body: <p>I've been looking all around but still not found the answer. Any idea how to return all kSecAttrAccounts from keychain? I would like to get back a list of every identifier I used when creating keychain items, then to choose the one I want to delete it using a "[KeychainWrapper deleteItemFromKeychainWithIdentifier:identifier] method".</p>
  
  <p>It works fine when I remember the username (identifier) I used when creating the account but cannot figure out how to have them all back when you created lots of them.</p>
  
  <p>I tried a kind of basic [dictionary objectForKey:(__bridge(id)kSecAttrAccount)] but it does not make it.</p>
  
  <p>Thanks a lot!!</p>
