I have been some lost hours with a somewhat strange problem that I cannot solve. The problem is in a call from a cell of a table in a succession of NavigationController views in a Storyboard. It seems as if the controls of the following view did not load, they are without initializing, and I do not understand what is the reason. Their values are null always. The view loads from a table source. If anyone has any idea about this question, I will thank for any clue to solve it. Thank you.
