Default value cannot be updated when the app switches the users' accounts

[wangqinggong]

Let me describe my question explicitly. For example, I define a key named 'autoSpeak ' in the GVUserDefault's category,and I set its default value is YES in the selector 'setupDefaults'. Then I run my app for the very first time, and log in. The UISwitch controlled by autoSpeak is close. Then I killed my app ,and then run it again,the UISwitch is open now. The same question happened when I switch to another user account.
I looked through the source code. I found setupDefaults is called in the selector init, but the object of GVUserDefault is singleton, so that is the reason, I thought.
Now I solve this problem by called setupDefaults again. But I do not think this is the perfect plan. I wish you, the author, can fix this issue in the source code .
