purpose: to give iOS newbies a warning when dealing with NSUserDefaults
audience: iOS newbies
context: throw the point: when dealing with userdefaults, what should be take care store data in userdefaults may be wrong how to do

In fact, the performance issue is not caused by NSUserDefaults but some hidden archive/unarchive and encrypt/decrypt, because NSUserDefault load data to memory and when modify, the data is not written directly back to disk but in some spectacular time, that's why the synchronize() exits.

Put all cost much time tasks in another thread is always good.

closing as done.
