  • I just want update my BadgeImage about file status immediately in finder sync extension ,when container app handle a file . For example, if the file has uploaded to serve success , container app can send a message to finder sync to change badgeImage immediately. The problem is I don't know how to do that . I have tried to use XPC , CFMessagePort ,it seems that not work out. – Allan hou Sep 13 '17 at 02:09
