UIToolbarController has become UITabBarController, and is pretty much
identical otherwise, although the property toolbarItem becomes
tabBarItem. Once I made those changes, my code compiled and ran fine.
What's really annoying is that XCode documentation tells me there is a
new iPhone SDK docset available, but each time I try and update, it
fails.
Also, none of the online documentation has been updated.
Although the samples have been.
Come on Apple, all together now :-)
I did find this page showing all the various API changes:
