Use a QLPreviewProvider to provide data-based previews.
|
|
|
|
To set up your extension as a data-based preview extension:
|
|
|
|
- Modify the extension's Info.plist by setting
|
|
<key>QLIsDataBasedPreview</key>
|
|
<true/>
|
|
|
|
- Add the supported content types to QLSupportedContentTypes array in the extension's Info.plist.
|
|
|
|
- Remove
|
|
<key>NSExtensionMainStoryboard</key>
|
|
<string>MainInterface</string>
|
|
|
|
and replace it by setting the NSExtensionPrincipalClass to this class, e.g.
|
|
<key>NSExtensionPrincipalClass</key>
|
|
<string>$(PRODUCT_MODULE_NAME).PreviewProvider</string>
|
|
|
|
- Implement providePreview(for:)
