Question

我在iOS9中有两种不同的情况进行共享扩展时出现问题（ 与iOS8一起正常工作 ）---（ 想要分享PDF ）：

首先使用PDF附件邮件转发邮件应用

长按PDF附件，然后从共享表中选择我的应用程序。它是在registrationTypeIdentifiers之后给我的：

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

从附件中打开PDF。它在UIDocumentInteractionController中打开PDF。 UIDocumentInteractionController提供共享功能。如果我单击共享图标，然后从共享表中选择我的应用程序。它是在registrationTypeIdentifiers之后给我的：

registeredTypeIdentifiers: (
    "com.adobe.pdf"
)

我应该怎样做才能在第二个场景中获得＆＃34; public.file-url＆＃34; 。

See the screen short of 2nd scenario

我在plist中使用下面提到的SUBQUERY：

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

为分享扩展制作自定义文档类型在关键的NSExtensionActivationRule下编写谓词例如：for pdf＆amp;我使用最大文档数量的谓词制作的图像为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>

IOS 9 - 共享扩展必须获取public.file-url
