无法使用我的应用程序打开电子邮件附件中的某些PowerPoint文件

Question

我需要将所有文档，图片和视频从邮件附件共享到我的应用程序，但遗憾的是，某些文档在面板上共享时错过了我的应用程序。这是我的info.plist的文档类型。

如果您只想让您的应用位于任何类型文件的列表中，您可以使用通用UTI public.data ...

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeIconFiles</key>
        <array/>
        <key>CFBundleTypeName</key>
        <string>Document</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>public.data</string>
        </array>
    </dict>
</array>
