I’ve spent over 6 hours on this issue by now and really need help. The RKCatalog example that I have compiles fine. But when I try to include the examples into my standalone project, I’m having all kinds of issues:

When I run the example from my main project, I get this exception:
2012-03-06 11:18:18.689 Tracker[1502:707] +[Article count:]: unrecognized selector sent to class 0xdaac4

This tells me that the selector is being sent to the NSManagedObject class, which does not have the ActiveRecord category applied to it. I simply cannot find where to put the import of NSManagedObject+(ActiveRecord) to make it work. I tried as high as the prefix header, but still no luck.

Do I need to import the libraries from the rest kit project into the main project and put them into the “Build phases>Link binary with libraries”? I’ve done so and moved the rest kit libraries on top of the regular frameworks.

Do I need to include the core data framework if I”m already using a core data library from the rest kit? I currently have both in the “Link binary with libraries”. Removing core data causes errors from the rest kit core data library.

Do I need to set header or library search paths to the rest kit folder if I’m already importing libraries from that project? I tried multiple folders for the derived data, and can confirm that the headers exist there.

I cannot add #import “RestKit.h” into the prefix header. It says that it cannot find the file. I can however add #import <RestKit/RestKit.h> or #import "RestKit/RestKit.h"
Here’s what in my prefix file right now:

#import <Availability.h>

#ifndef __IPHONE_5_0
#warning "This project uses features only available in iOS SDK 5.0 and later."
#endif



#ifdef __OBJC__
    #import <UIKit/UIKit.h>
    #import <Foundation/Foundation.h>
    #import <RestKit/RestKit.h>
    #import <RestKit/CoreData/CoreData.h>
    #import "RestKit/CoreData/NSManagedObject+ActiveRecord.h"

#endif

I know it has to be something really simple, but I keep spending hours on this issue and just cannot see it. The RKCatalog project works without so much customization. WHat am I doing wrong with my project settings?

Thank you for any help!
