Read Info.plist from prefix.pch

Question

Is it possible to read a value from my Info.plist file in the prefix.pch file and sat a macro according to that value?

For instance, if I have a boolean property in the Info.plist called UseSomeResource I would like to make a #define USE_SOME_RESOURCE 1 if the value of that property is YES.

Answer 1

In theory yes, albeit I don't think the .pch is the best place to put it. I'd suggest placing this macro within a Macros.h, or some similar mechanism, that you import within your .pch

#define USE_SOME_RESOURCE ([[[[NSBundle mainBundle] infoDictionary] objectForKey:@"UseSomeResource"] boolValue])

It's worth noting that this will still determine the value at runtime, not at compile time. If you want it to be run at compile time, you may need to write a script as part of one of your build phases, that reads the Info.plist, and creates a header file, which is then included as part of your project. This seems like quite a roundabout method, and as such I highly suggest the runtime alternative.
