iOS SDK 4.2 includes a new UIApplicationDelegate method called application:openURL:sourceApplication:annotation:. It is a replacement for application:handleOpenURL: and offers more information about the calling application: not only do we get the bundle identifier of the calling app, but also, in the annotation argument,
A property-list object supplied by the source application to communicate information to the receiving application.
Great, this should offer a lot of opportunities for a more direct interaction between multiple third-party apps!
