Both of these items have been knocking around the media or a few weeks. Pastrykit first and since the launch of the iPad Adlib.
But what is in the wild? There is a lot of speculation as to what the kits are for and there is some revers engineered code libraries. But no word from Apple.
Personally i think this is part of the the Apple “No Flash” campaign and the move to ensure more open standards and to push HTML 5 plus css 3 to achieve the same ends.
Watching the iPhone 4 beta release i think Jobs was hinting in the iAd section Â when he was demonstrating the Â interstitial ads Â that there was something on the way. ANother interesting straw in the wind is the fact that nothing but native objective c and cocoa app will be allowed on the platforms in future.
