Working document list of iPad/iPhone programming restrictions (features?).

  • There’s no multitasking except for Apple-blessed applications.  For example, you can play a song while you are doing something else.  However, say you have a location-based app and you want to notify the user when they’ve reached a certain location even if they are doing something else at the time.  How would you do that?
  • Only C, C++, Objective-C are supported.  An interpreted language that could potentially have a smaller footprint would be nice, BASIC or Rexx perhaps.
    [apparently, this is a relatively new restriction and might be subject to an antitrust probe.]
