Where are the ios SDK header files located? and where is osx?

Question

I can open the header files by pressing a command in Xcode, but I want to know where they are located.

I want to analyze them for a project (as text files, not as header files).

I looked on my drive - to find them.

For example, where is UIViewController.h located?

Answer 1

SDK headers are located in the Xcode installation.

For instance:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIViewController.h
