Certainly sometimes +viewWillAppear:+ or +viewWillDisappear:+ arrives without 
the corresponding +viewDidAppear:+ or +viewDidDisappear:+. I filed a bug on 
this a couple of years ago and was told that this was working as expected: 
nothing in the contract guarantees that "will" will be followed by "did", they 
told me, though I tried to argue that the contract is right there in the name. 
As you say, it's really bad; please, please file a bug. The guy giving the WWDC 
videos on this topic a frighteningly cavalier attitude about this; he seems 
impervious to any understanding of the fact that we need coherent reliable 
order and sequence for these events. m.
