Apple Mach-O Linker Error (IAP)

Question

I'm struggling with in-app purchases. Whenever I import StoreKit, I receive this error.
I've been at this for days with no luck.. Someone help?

Header File:

#import <StoreKit/StoreKit.h>    

#define kInAppPurchaseManagerProductsFetchedNotification          @"kInAppPurchaseManagerProductsFetchedNotification"

@interface InAppPurchaseManager : NSObject <SKProductsRequestDelegate>
{
    SKProduct *proUpgradeProduct;
    SKProductsRequest *productsRequest;
}
@end

Implementation File:

#import "IAPManager.h"

@implementation InAppPurchaseManager 

- (void)requestProUpgradeProductData
{
    NSSet *productIdentifiers = [NSSet 
       setWithObject:@"com.runmonster.runmonsterfree.upgradetopro" ];
    productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers];
    productsRequest.delegate = self;
    [productsRequest start];
}

#pragma mark -
#pragma mark SKProductsRequestDelegate methods

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
    NSArray *products = response.products;
    proUpgradeProduct = [products count] == 1 ? [[products firstObject] retain] : nil;
    if (proUpgradeProduct)
    {
        NSLog(@"Product title: %@" , proUpgradeProduct.localizedTitle);
        NSLog(@"Product description: %@" , proUpgradeProduct.localizedDescription);
        NSLog(@"Product price: %@" , proUpgradeProduct.price);
        NSLog(@"Product id: %@" , proUpgradeProduct.productIdentifier);
    }

    for (NSString *invalidProductId in response.invalidProductIdentifiers)
    {
        NSLog(@"Invalid product id: %@" , invalidProductId);
    }


    [productsRequest release];

    [[NSNotificationCenter defaultCenter] postNotificationName:kInAppPurchaseManagerProductsFetchedNotification object:self userInfo:nil];
}
@end

The error thats killing me:

    Undefined symbols for architecture armv7:
      "_OBJC_CLASS_$_SKProductsRequest", referenced from:
          objc-class-ref in IAPManager.o

Because you have added the "Header", not the binary. Put the StoreKitFramework into the buildPhase->Link binary with libraries. Magically this will work ;)

You forgot to add the StoreKit.framework to the libraries you link against.

This link shows how you can add it.
