I am making an iPhone app and it requires IOKit and IOSurface framework. I have included these frameworks in the project. When I expand the framework once it's linked, I can see the headers. However, when I try:
#include <IOKit/IOKitLib.h>
#include <IOSurface/IOSurface.h>
...it says it cannot find the file. I am running Xcode 6 with the app targeted for iOS 7+.
I have also tried this: IOKit Not found ...and all that says is that the file was found after I run the command.
and this: symbol(s) not found in XCode, Cocoa application
Both do not work for me. It looks like this person is having a similar problem, if it helps at all: Adding IOKit to iOS Project
