问题描述
使用 Swift5.3.2,iOS13.0,
我的共享扩展适用于图像和视频。
但是它不适用于 PDF。
问题是我的应用程序在我尝试与我的应用程序共享的 PDF 文档的共享应用程序列表中不可见。
我知道必须在 info.plist 中正确设置规则。
我尝试了以下两次尝试 - 但都没有成功!
谁能告诉我一个 PDF 共享扩展在 iOS 中需要什么?
尝试 1:Info.plist
<key>NSExtension</key>
<dict>
<key>NSExtensionAttributes</key>
<dict>
<key>NSExtensionActivationRule</key>
<dict>
<key>NSExtensionActivationSupportsFileWithMaxCount</key>
<integer>20</integer>
<key>NSExtensionActivationSupportsWebPageWithMaxCount</key>
<integer>1</integer>
<key>NSExtensionActivationSupportsWebURLWithMaxCount</key>
<integer>1</integer>
<key>NSExtensionActivationSupportsImageWithMaxCount</key>
<integer>100</integer>
<key>NSExtensionActivationSupportsMovieWithMaxCount</key>
<integer>25</integer>
</dict>
</dict>
<key>NSExtensionPointIdentifier</key>
<string>com.apple.share-services</string>
<key>NSExtensionPrincipalClass</key>
<string>CustomShareNavigationController</string>
</dict>
尝试 2:Info.plist
<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.file-url"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.url"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.jpeg"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.png"
).@count == $extensionItem.attachments.@count
).@count == 1
</string>
</dict>
<key>NSExtensionPointIdentifier</key>
<string>com.apple.share-services</string>
<key>NSExtensionPrincipalClass</key>
<string>CustomShareNavigationController</string>
</dict>
解决方法
当您在 Safari 中启动 PDF 共享时,它实际上会考虑 2 个输入项:PDF 和 URL。由于您的 NSExtensionActivationRule
谓词明确指出 @count == 1
,它会返回 false,因为有超过 1 个元素与您的谓词匹配。因此,修复方法是将 @count == 1
更改为 @count >= 1
或最适合您的应用程序的任何逻辑。
更新了对我有用的查询:
<key>NSExtensionActivationRule</key>
<string>
SUBQUERY (
extensionItems,$extensionItem,SUBQUERY (
$extensionItem.attachments,$attachment,ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "com.adobe.pdf"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.file-url"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.url"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.jpeg"
|| ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.png"
).@count == $extensionItem.attachments.@count
).@count >= 1
</string>
