PFQuery order by not Display in PFQueryTableViewController

Question

in this TableViewController (I'm working with Parse.com) I entered all registered users and SearchDisplayControll for research.

Now I have only one problem .

I can not see in alphabetical order, the names of registered users ... I do not understand why.

The alphabetical order only works when the active searchDisplayControll where am I doing wrong?

Thanks to all
