Registering Delphi app to handle file type on iOS

Question

I found this article on how to associate an xCode iOS app with a file type / extension:

Email Tutorial for iOS: How To Import and Export App Data Via Email in your iOS App

Which says:

other app wants to send your app a file, it does so via one of two methods: via application:didFinishLaunchingWithOptions, passing the URL in the UIApplicationLaunchOptionsURLKey, or via application:handleOpenURL.

Will Delphi be able to do the above as well? It has been a long time since I last used Delphi for mobile, but I am contemplating buying it again. I just want to make sure there are no showstoppers to stop me from doing things like this.

I have found this which might indicate that it is possible with recent versions of Delphi although not 100% sure:

And someone else "hacking" units in an earlier version (close to the same problem)

Answer 1

You can definitely do it with Delphi. The more interesting question is if FMX supports it so it is ready to use without patching FMX.

FMX/XE8 implements application:openURL:sourceApplication:annotation:. When this is called, FMX will send a TApplicationEvent.OpenURL application event with TiOSOpenApplicationContext as context using the TMessageManager. You can subscribe to that message.

I don't see any file url handling in application:didFinishLaunchingWithOptions. You'd have to patch FMX.Platform.iOS for that.
