Where to find updates for deprecated functions?

Xcode4 will tell you if a function is deprecated but does not provide any info on what to use as the latest update for that function. What is the best way to find out the updated version of any de开发者_运维问答precated function?

I always search the documentation with the function name and get the new version of the old methods. It works all the time.

There is a drop down(Doc Set) to select the libraries you want to search, in the Documentation window
