Table view methods not executing

I am able to get a table view to populate with data except when I use custom style table view cells. Then the numberOfRowsInSection and cellForRowAt tableView functions will not even execute. I was sure to set the class of the table view cell and to name the cell and to refer to the cell by its identifier. Anyone have any suggestions?

Did you set the delegate?

Can you specify what happen? because from what you have written seems the problem came out only when you use custom cells.

try to post some code to understand well the problem
