I'd say that it doesn't usually matter, unless:

• The method is doing initialisation of instance variables (which viewDidLoad usually wouldn't be doing, as that's the init method's job), in which case the super call should be at the start.
• The method is doing deallocation of instance variables, in which case the super call should be at the end.

I may have missed some important cases, though.
