Yes, fair enough. There are a lot of indeterminacies in the framework - for example, it might perform an animation for whose finish you get no notification, or you might need to wait until after the next "redraw moment" (as I call it) - and one gets into the habit of using delayed performance as a way of skirting these. But I certainly see why this is a different sort of case. m. > On Jan 16, 2011, at 6:46 PM, Matt Neuburg <m...@tidbits.com> wrote: > >> On Sun, 16 Jan 2011 13:47:06 -0800, G S <stokest...@gmail.com> said: >>> On Sun, Jan 16, 2011 at 11:47 AM, Luke Hiesterman <luket...@apple.com> >>> wrote: >>>> viewDidLoad is called the first time the view property of the vc is >>>> accessed - that's when loading happens.
