Swift共享分享扩展名为4种文件类型

Question

我想制作一个可以共享此类文件的shareextenion：

vcard-最大1项图像 - 最大5个项目视频 - 最大5个项目文字 - 最大1个项目URL-最大1个项目

我在nsextensionAttribute中使用此代码：

SUBQUERY (
extensionItems,
$extensionItem,
SUBQUERY (
    $extensionItem.attachments,
    $attachment,
    ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.vcard"
).@count == 1 || 
SUBQUERY (
    $extensionItem.attachments,
    $attachment,
    ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.image"
).@count < 6 || 
SUBQUERY (
    $extensionItem.attachments,
    $attachment,
    ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.video"
).@count < 6 ||
SUBQUERY (
    $extensionItem.attachments,
    $attachment,
    ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.plain-text"
).@count == 1 ||
SUBQUERY (
    $extensionItem.attachments,
    $attachment,
    ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.url"
).@count == 1
).@count == 1

问题是该扩展名在其他文件类型示例中可见。doc或.pdf和＆lt;6不起作用！

有什么想法？

   <key>NSExtensionActivationRule</key>
        <string>SUBQUERY(extensionItems, $extensionItem, SUBQUERY($extensionItem.attachments, $attachment, ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.plain-text").@count >= 1).@count >= 1
            OR SUBQUERY(extensionItems, $extensionItem, SUBQUERY($extensionItem.attachments, $attachment, SUBQUERY($attachment.registeredTypeIdentifiers, $uti, $uti UTI-CONFORMS-TO "public.url" AND NOT $uti UTI-CONFORMS-TO "public.file-url").@count >= 1).@count >= 1).@count >= 1
            OR SUBQUERY(extensionItems,$extensionItem,SUBQUERY($extensionItem.attachments,$attachment,ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.image").@count == $extensionItem.attachments.@count AND $extensionItem.attachments.@count &lt;= 5).@count == 1
            OR SUBQUERY(extensionItems,$extensionItem,SUBQUERY($extensionItem.attachments,$attachment,ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.movie").@count == $extensionItem.attachments.@count AND $extensionItem.attachments.@count &lt;= 5).@count == 1

            </string>
