While this blog didn’t really take off like I wanted it to, the new one will focus specifically around iPhone, Games Development, and my company OniMobi.

I’ll no longer be checking or posting to this blog, so I’d recommend following me to my new one :)

So watch this space (if anybody does in fact follow this blog - which seems unlikely)!

Thanks a lot Apple.

In short you can now only register 100 AdHoc devices per year, not at any one time. Why the hell did they change that? If anything, we’re all begging for more AdHoc versions!!

How on earth can you run a large scale beta test of a game with the current system? Answer: You can’t.

This error is really a generic error that says the iPhone could not verify the code signature, and so didn’t complete installing.

Things to double check:

  1. Bundle Identifier is correct and matches with the one selected in the Provisioning Profile.
  2. The deviceID has been correctly added to the Provisioning Profile.
  3. The Entitlements.plist file has been added to the project (see the howto doc on Distribution profiles). This is what catches most people out, since you don’t need it for development.
  4. Ensure the get-task-allow check box is unticked in the Entitlements.plist
  5. The Provisioning Profile has been dragged into iTunes as well as the .app or .ipa file.

Also, for AdHoc distribution, I’d recommend packaging up the .app as an ipa file. This is better compatability for windows, because a .app file is a just a folder, and it also allows the iTunesArtwork to be displayed.

At Greenius we use a simple script to package up an AdHoc build. Note you should edit the variables at the top for the appname and the build folder. Later I plan to update this so its a bit more flexible and can take the options from the command line. It also expects a iTunesArtwork.png file for the iTunesArtwork, which should be a 512×512 png.

myLabel.numberOfLines = 0;

Easy!
