iPhone - MBProgressHUD, Data Controller and Sudzc - ios

Question

I am using the following wrapper for SOAP web services: http://www.sudzc.com/
and the following MBProgressHUD for the activity indicador: https://github.com/jdg/MBProgressHUD
Don't know how i can use the MBProgressHUD before a view get call.
I'm also using a Data Controller where the call of the SOAP services is made.
Here is my code.
