Before using any heavy-handed solutions that involve deleting all
the LS
data folks should be aware that such any approach that resets
*everything*
in Launch Services will remove all of the Open With customizations
that
aren't file-specific and the "trusted" status of applications.
Yes, this tells LS to start from scratch. And that's a very good
point about the Open With customizations. In my case, the few times
I've found that LS has truly gone wonky, the above was the only
thing that worked. Of course, I'm open to suggestions.
Note that wiping the LS database doesn't actually erase all of the
binding preferences the user has established. It just erases all of
the cached Info.plist application data from the apps on your system.
Also, and of course I may eat crow on this point, wiping the LS
database isn't quite the magic bullet it was under 10.2 and earlier.
There is likely something else going on. Ensuring that rebuilding
your app changes the mod date on the bundle directory is a good place
to start. Changing the mod date is enough to trigger re-registration
when you drag a file over your app's icon.
As I recall, simply Option-dragging an application to another
folder should
cause the Finder to update its entry in the LS database.
I've heard that too, but it's never worked here.
Again, this makes it sound like wiping the LS database won't help you.
I pasted your CFBundleDocumentTypes XML into an empty app project in
Xcode, built it, and it worked correctly w.r.t. dragging a .mov file
onto the app icon. What tool are you using the create the app bundle?
