cocoa - OSX App - Associated file types and icons not updating (Launch Services) -

-

i have mac app open ".png" file types. able application make default app opens ".png" files , double clicking files launch app.

however, can't seem update icon on .png files - shows default icon thumbnail of image.

i have file called icon.icns in project, , following block in info.plist file:

<key>cfbundledocumenttypes</key> <array>     <dict>         <key>cfbundletypeextensions</key>         <array>             <string>png</string>         </array>         <key>cfbundletypeiconfile</key>         <string>icon</string>         <key>cfbundletypename</key>         <string>png</string>         <key>cfbundletyperole</key>         <string>viewer</string>     </dict> </array>

what's weird if restart computer, icons update, after second or change system default.

thanks!
