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. -- matt neuburg, phd = [email protected], http://www.apeth.net/matt/ Programming iOS 7! http://shop.oreilly.com/product/0636920031017.do iOS 7 Fundamentals! http://shop.oreilly.com/product/0636920032465.do RubyFrontier! http://www.apeth.com/RubyFrontierDocs/default.html _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
