macOS Saving states using NSUserDefaults

I am binding check box value with shared user defaults controller in Interface Builder. I am registering defaults as well.
but user defaults not working. it doesn't saves the status of check box.
There is no plist file created at path /Library/Preferences for my application identifier.

Sorry, But i have checked for ~/Library/Preferences.
There is no any plist file created over there.
can you tell me the steps from beginning for saving states of check box.
I have given model key path for check box but i am not getting.

I am sending you my test application in attachment ?

you can find what is the problem ?


Thanks.

I got what was the problem ?
Actually i was quiting application from debugger. so it was not saving the state of check box. once i quit from Application Menu , it saved the state.
So, I can understand that it will save the states on quiting the application, not on registering defaults.

That concludes , to save the state we have to quit the application. or we can use the method synchronize or setValue:forKey to save the state when application is Running.

am i correct ? what is correct method to save?


Thanks.
