Hello, I'm currently learning Obj-C and Cocoa from various books. Most of these books are pre-xcode 3.1 and refer to documentation on the local machine /Documentation folder. Because i'm using XCode 3.1 - this documentation isn't there anymore. I realise that the docs are built in to xcode now - but can't find any of the reference it points to. For instance, where is the Foundation Objective-C reference? My book claims there is a complete reference which can be browsed through to see other objects available. In fact, are there any complete quick references to all the objects available??
