Theres a "constants.h" in the UICatalog sample, but it's local to that sample and is clearly just a way for the sample developer to make his/her life easier. It carries with it all the problems mentioned above ... if anything changes the "standard sizes" in the future, this sample stops working properly.

It sucks to have to query other objects to get your placement right, but it's how you ensure things work properly when the environment changes. The expanding "in-call" status bar is a perfect example. If you hard-code 20 "units" to avoid the status bar, your app breaks while in a call. And, that's something you're not likely to notice in the simulator (because, if you thought about it enough to try that option in the simulator, you probably would have thought about it while coding the app!)
