I need to store a persistent data for my Mac application. I’m able to store this data in a plist or NSUserdefaults. But I want to store this persistent data in my application folder, so that when I delete the app (move to trash) from the Mac, this persistent data also will get deleted. I want this to work like that. What would be best approach to do this and how can I store persistent data in my app folder, so that the data also gets deleted when the app is deleted?

NSUserDefaults *ud = [NSUserDefaults standardUserDefaults];        
[ud setObject:@"1" forKey:@"APPLAUNCHED"]; // store user default
[ud synchronize];
