Classes imported in .pch file in xcode not working, why?

Question

I have a concern with my .pch file in Xcode 5.

I have following code in my .pch file--

#ifdef __OBJC__

#import <Example/Example.h>

#endif

But when i use Example.h class in my code it is not working. When i use code like-

[Example sharedInstance];

xcode shows error "Use od undeclared identifier Example". What is the problem?

Answer 1

This Screen Shot from XCode 6.1 shows how I got this to work - and therefore may prove helpful.

Look at the bold text, mid-way down, in the "Apple LLVM 6.0 - Language" TARGETS / Build Settings area.

Notice how the bold text "Precompile Prefix Header" has been set to YES, and the path to the pch file in "Prefix Header" is set with ProjectName/YourPCHFile-Prefix.pch

Answer 2

You will need to include the path to the headers in the "Header Search Path" build settings so that the preprocessor/compiler can find the headers.
