tableView with prototype cell not reloading data

Hey Guys I'm trying of figure out what i'm doing wrong with no luck

basically I have a webservice that returns some results that I want to put them in table in an iOS app

I am using prototype cell with 3 labels do put the results per line of the table

The problem is that the table is always empty

I checked that no values regarding the web service response are nil

Can anyone Help Me?
