Do I need to synchronize in NSUserDefaults after deleting an object from the keys?

Question

I searched for a while, I need to synchronize if I do:

[[NSUserDefaults standardUserDefaults] removeObjectForKey:kType];

After that should I do ?:

[[NSUserDefaults standardUserDefaults] synchronize];

Waiting for your answers in this question.
