ios - iOS 9-强制共享扩展以获取public.file-url

我在iOS9的两种不同方案的共享扩展中有一个问题(与iOS8 配合良好)---(希望共享PDF ):

首先转到带有PDF附件邮件的邮件应用程序-

长按PDF附件，然后从共享表中选择我的应用程序。它是通过registeredTypeIdentifiers给我的:

registeredTypeIdentifiers: (
    "public.file-url",
    "com.adobe.pdf"
)

从附件中打开PDF。它是在UIDocumentInteractionController中打开的PDF。 UIDocumentInteractionController提供共享功能。如果我单击共享图标，则从共享表中选择我的应用程序。它是通过registeredTypeIdentifiers给我的:

registeredTypeIdentifiers: (
    "com.adobe.pdf"
)

我应该怎么做才能在第二种情况下获得“public.file-url” 。

See the screen short of 2nd scenario

我在plist中使用以下提及SUBQUERY的方法:

SUBQUERY (
          extensionItems,
          $extensionItem,
          SUBQUERY (
                    $extensionItem.attachments,
                    $attachment,

                    (
      ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.file-url"
      || ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "com.adobe.pdf"
      || ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.image"
      || 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"

       )

                    ).@count == $extensionItem.attachments.@count
          ).@count == 1

最佳答案

为共享扩展名定制文档类型
在键NSExtensionActivationRule下写谓词
例如:对于pdf和图像，我做出以下谓词，最大文档数为1。

<key>NSExtension</key>
<dict>
<key>NSExtensionAttributes</key>
<dict>
    <key>NSExtensionActivationRule</key>
    <string>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"
        )
        ).@count == $extensionItem.attachments.@count
        ).@count == 1</string>
