CryptoPassphrase  Artifact [06c53e33a8]

Artifact 06c53e33a8cf4a07038366012ac04c02eee28c47ee57e4fe914e8c6111ac1ddd:

• File iOS/AddSiteController.m — part of check-in [461f9773b4] at 2016-10-09 15:53:41 on branch trunk — Add initial iOS application

  This is already in a working state, but is still missing a few things.
  For example, there is no proper progress indication during generation
  and the UI just hangs and there's no way to delete a site yet. (user: js, size: 2930) [annotate] [blame] [check-ins using]
