You can automatically import a library in all of the source files of your project by adding the import to the prefix header of your project. To do this, simply add the import function to the Prefix.pch file located in the other sources folder of your project hierarchy.

//
// Prefix header for all source files of the 'Locations' target in the 'Locations' project
//

#import <Availability.h>

#ifndef __IPHONE_3_0
// #warning "Projects that use Core Data only build using iPhone SDK 3.0 and later"
#endif

#ifdef __OBJC__
