How do I associate file types with an iPhone application?
I have seen in a few different places that when clicking a link, it asks me if I want to open that file in a number of apps, such as iBooks, FileMagnet, or other apps.
Is there a way in the SDK, that when someone clicks on a link in Safari or an email to a .kml or .gpx file, that I can ask if they want to open it in my app?
