Make UITextField inside a table view visible scrolling

Question

I have a UITableViewController, a bunch of sections and rows, and for each row I added a UITextField as a subview, right aligned in the row itself.

If the users taps on the row, I locally save the indexPath, make the corresponding text field become the first responder and finally, when the keyboard appears, I make the table view scroll so that the row remains visible.

I am facing the problem to obtain the same behaviour when the user taps the text field instead. In this case the didSelectRowAtIndexPath: method isn't called, so I do not know how to tell the table view to scroll to make sure that the "selected" row is still visible.

Probably the whole process is not correct. Do you know a way to solve it?

Thanks a lot!
