Hi All, My development environment is XCode 4.3.2 on Lion. My cocoa XCode .app gets installed in the Applications folder. The app generates debug log files under /Users/Logged-inUser/Library/Application Support/MyApp/ (logs needed for debugging issues reported by customers) If I were to drag the application and trash out the same, though the application is uninstalled from the machine, these log files continue to be there. Is there a mechanism by which I can get notified when the user drags the app to trash for uninstallation so that I can handle the notification to perform necessary cleanup? Thanks & Regards.
