I've been following the brilliant instructions in this answer, which work perfectly. However, my file type is mime "application/notforquicklook" and quicklook still tries to open it. This causes general gear spinning and nothing happening.
How can I get around this problem? My files are compressed plists. Before I was using full XML plists, which worked fine, but they are too big (with no advantage).
Is this a question of choosing the right MIME type, or something else?
in fact, you should assign "public.data" to your "Conforms to UTIs" (UTTypeConformsTo) in "Exported Type UTIs" (CFBundleDocumentTypes)
<dict>
<key>UTTypeConformsTo</key>
<array>
<string>public.data</string>
</array>
<key>UTTypeDescription</key>
<string>Scrollshow Presentation</string>
<key>UTTypeIdentifier</key>
<string>com.plimse.scrollshow</string>
<key>UTTypeTagSpecification</key>
<dict>
<key>public.filename-extension</key>
<string>scrollshow</string>
<key>public.mime-type</key>
<string>mime/x-scrollshow</string>
</dict>
</dict>
This worked for me, remove this from the xxx-info.plist file:
<key>UTTypeConformsTo</key>
<array>
<string>public.xml</string>
</array>
Now only my app shows up in the mail app.
