I am currently developing an iOS application containing a Share extension.
I realized that the
NSExtensionActivationSupportsImageWithMaxCount
key doesn't allow me to activate my Share extension on .jpeg or .png URLs ("public.image" UTI, kUTTypeImage) under Safari (ie : an imgur link).
I can still activate and test my extension if I switch to a NSActivationRule = TRUEPREDICATE, but it is forbidden for a released app.
I filled a bug on radar in case of it wasn't wanted (even facebook, twitter, etc... aren't activated on this URLs)
Right now, I would like to combine the following keys and the "public.image" in a NSPredicate string as the documentation says (https://developer.apple.com/library/archive/documentation/General/Conceptual/ExtensibilityPG/ExtensionScenarios.html#//apple_ref/doc/uid/TP40014214-CH21-SW8)
So I have to translate the keys to a UTI
So far I have translated:
- NSExtensionActivationSupportsFileWithMaxCount
to "public.file-url" kUTTTypeFileURL
- NSExtensionActivationSupportsMovieWithMaxCount
to "public.movie" kUTTypeMovie
- NSExtensionActivationSupportsText
to "public.text" kUTTypeText
- NSExtensionActivationSupportsWebURLWithMaxCount
to "public.url" kUTTypeURL
But I don't find the type translation for:
NSExtensionActivationSupportsWebPageWithMaxCount
, "public.HTML" is it kUTTypeHTML ?Does somebody already used this keys inside a predicate?
What I ended up doing is 1) allowing TRUEPREDICATE temporarily, and using some logic like this`
NSExtensionItem *item = extensionContext.inputItems.firstObject;
if ( item )
{
NSItemProvider *itemProvider = item.attachments.firstObject;
if ( itemProvider )
{
NSArray *registeredTypeIdentifiers = itemProvider.registeredTypeIdentifiers;
NSLog( @"registeredTypeIdentifiers: %@", registeredTypeIdentifiers );
}
}`
This will give you all the types of the document you want to share (example: "public.url"). Because of the multiple types, my predicate became a little complex:
SUBQUERY (
extensionItems,
$extensionItem,
SUBQUERY (
$extensionItem.attachments,
$attachment,
(
ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "com.adobe.pdf"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.image"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.plain-text"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.png"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.jpeg"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.jpeg-2000"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.tiff"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "com.compuserve.gif"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "com.microsoft.bmp"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "com.microsoft.word.doc"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "org.openxmlformats.wordprocessingml.document"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.comma-separated-values-text"
)
AND
(
NOT ( ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "com.adobe.photoshop-image" )
)
).@count == $extensionItem.attachments.@count
).@count == 1
This basically looks for any file type for image (other than adobe psd), pdf, txt, csv or doc/docx. It also only allows 1 document to be shared at a time.
It looks like kUTTypeImage includes PSD - hence my blocking of that format ( "com.adobe.photoshop-image" ).
