Answer 1

If you've set UITableView datasource and delegate from IB then it will at least go for numberOfRowsInSection method when you push to the view, however if you're showing data from an NSArray, it'll return count ZERO if array is still empty, so table won't go for other methods to call.

In practice, I'm pulling data from web service to feed the table, so I am not setting up the datasource and delegate from IB instead once I get the data and status OK response I'd set the tableview.datasource = self and tableview.delegate = self and then call reloadData method to update table. This ensures that it won't go for numberOfRowsInSection method as you don't need to call it up without having the data.
