I'm just looking for a way to have my app proposed in the "Open with" menu.
I saw this StackOverflow topic on the subject, I set the necessary lines in the plist file but my app is still not proposed.
How can I do this ?
Here is the code I set in the plist :
<key>CFBundleDocumentTypes</key>
<array>
<dict>
<key>CFBundleTypeExtensions</key>
<array>
<string>pdf</string>
</array>
<key>CFBundleTypeIconFile</key>
<string>app.icns</string>
<key>CFBundleTypeName</key>
<string>public.pdf</string>
<key>CFBundleTypeRole</key>
<string>Editor</string>
<key>LSHandlerRank</key>
<string>Owner</string>
<key>LSItemContentTypes</key>
<array>
<string>public.pdf</string>
</array>
</dict>
<dict>
<key>CFBundleTypeExtensions</key>
<array>
<string>png</string>
</array>
<key>CFBundleTypeIconFile</key>
<string>app.icns</string>

<key>LSHandlerRank</key>

and

Answer 1

It looks like all you did was copy those entries from the other answer you linked to.
For PDF files and PNG images you don't need the second part (imported declarations) at all. Those are well known document types.
For the document types, I just do this:
<key>CFBundleDocumentTypes</key>
<array>
<dict>
<key>CFBundleTypeName</key>
<string>PDF</string>
<key>LSHandlerRank</key>
<string>Alternate</string>
<key>LSItemContentTypes</key>
<array>
<string>com.adobe.pdf</string>
</array>
</dict>
<dict>
<key>CFBundleTypeName</key>
<string>PNG</string>
<key>LSHandlerRank</key>
<string>Alternate</string>
<key>LSItemContentTypes</key>
<array>
<string>public.png</string>
</array>
</dict>
</array>
