When I run it and write the answer the label's text doesn't change.I tried stringWithFormat but it doesn't work.The strange part is the session label's text changes.But I couldn't find any differences

Answer 1

It seems that Question label's text changes only in method:
-(void)questioning;
But I can't find where you are calling one. Set breakpoint on entrance of it, mb you are never getting there. As I understood your code [self questioning] should be called in viewDidLoad and at the end of GoBtn: methods.
P.S.
You should pay attention to the Coding Guidelines for Cocoa, General Coding Standards and Conventions. Especially to the naming variables, data types, methods e.t.c. (E.g. variables shouldn't start with capital letter, Class or structures should)
