iphone - Apple Mach-O 链接器错误 (IAP)

Question

我正在为应用内购买而苦恼。每当我导入 StoreKit 时，我都会收到此错误。
我已经在这几天没有运气了..有人帮忙吗？

头文件:

#import <StoreKit/StoreKit.h>    

#define kInAppPurchaseManagerProductsFetchedNotification          @"kInAppPurchaseManagerProductsFetchedNotification"

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

执行文件:

#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

让我丧命的错误:

    Undefined symbols for architecture armv7:
      "_OBJC_CLASS_$_SKProductsRequest", referenced from:
          objc-class-ref in IAPManager.o
    ld: symbol(s) not found for architecture armv7

Answer 1

因为您添加的是“ header ”，而不是二进制文件。将 StoreKitFramework 放入带有库的 buildPhase->Link 二进制文件中。神奇的是，这会起作用；)
