ios - Share extension only with specific URL -

is there way filter share extension show when, example, url domain specific one?

for example, want show app extension when user sharing google link:

http://www.google.com/?somequery

if i'm filtering urls, code below sufficient:

subquery (     extensionitems,     $extensionitem,     subquery (         $extensionitem.attachments,         $attachment,         $attachment.registeredtypeidentifiers uti-conforms-to "public.url"     ).@count == $extensionitem.attachments.@count ).@count == 1 

in case predicate access $attachment's registeredtypeidentifiers property , evaluate it. want able match regex against value inside $attachment, this:

subquery (     extensionitems,     $extensionitem,     subquery (         $extensionitem.attachments,         $attachment,         $attachment.registeredtypeidentifiers uti-conforms-to "public.url" ,         $attachment.value matches "^http\:\/\/www\.google\.com\/"     ).@count == $extensionitem.attachments.@count ).@count == 1 

... extension invisible when application don't support url shared host app.

ps: note url domain used example. real one, of course, have meaning used this.
