无法使用我的应用程序从电子邮件附件中打开某些PowerPoint文件

Question

我需要将来自附件的所有文档，图像和视频共享到我的应用程序，但不幸的是，有些文档从面板上的共享中丢失了我的应用程序。这里是我的info.plist的文档类型。

<key>CFBundleDocumentTypes</key> 
<array> 
    <dict> 
     <key>CFBundleTypeIconFiles</key> 
     <array/> 
     <key>CFBundleTypeName</key> 
     <string>Document</string>
