iPhone: [super viewDidUnload] calling order

Question

Hi,

I would like to know if there is any difference between calling [super viewDidUnload] before realeasing properties or after it.

Thank you!

  self.webView = nil;
  self.fullText = nil;
  [super viewDidUnload];

or

  [super viewDidUnload];
  self.webView = nil;
  self.fullText = nil;

Answer 1

This depends on what the superclass does in viewDidUnload. If it's just a standard UIViewController, either will do because -[UIViewController viewDidUnload] does nothing.

Answer 2

This only matters if the superclass of your view actually does something in viewDidLoad. The default UIViewController doesn't do anything in viewDidLoad so if your view is a standard UIViewController then you can put [super viewDidLoad] anywhere in the viewDidLoad method. However, if super does something in viewDidLoad, then it does matter where you put [super viewDidLoad].
