本文详细解析了如何在iOS应用中通过StoreKit框架实现内支付流程，包括验证支付能力、获取商品信息、接收App Store回应及处理支付状态。同时，介绍了商品恢复流程，确保用户购买历史的完整性。

1、首先验证是否能够支付
- (BOOL)checkCanMakePayment
{
    if ([SKPaymentQueue canMakePayments]) {
        return YES;
    } else {
        return NO;
    }
}
2、其次获取需要支付商品信息
- (void)purchaseProductWithIndentifier:(NSString *)identifier
{
    if (identifier == nil || [@"" isEqualToString:identifier]) {
        if (self.delegate && [self.delegate respondsToSelector:@selector(AppStorePurchaseSuccess:)]
{
            [self.delegate AppStorePurchaseSuccess:identifier];
        }
        return;
    }
    [[ITTActivityIndicator currentIndicator] displayActivity:@"获取商品信息中..."];
    SKProductsRequest *request= [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:identifier]];
request.delegate = self;
[request start];
}

3、接收来自App Store的回应
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
    [[ITTActivityIndicator currentIndicator] hide];
    NSArray *myProducts = response.products;
    // Populate your UI from the products list.i
    // Save a reference to the products list.
    if (myProducts && [myProducts count] > 0) {
        SKProduct *selectedProduct = [myProducts objectAtIndex:0];
        SKPayment *payment = [SKPayment paymentWithProduct:selectedProduct];
        [[SKPaymentQueue defaultQueue] addPayment:payment];
    }
    else {
        [[ITTActivityIndicator currentIndicator] displayActivity:@"获取商品信息失败！"];
    }
}

4、对支付进行相应的处理
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    for (SKPaymentTransaction *transaction in transactions)
    {
        switch (transaction.transactionState)
        {
            case SKPaymentTransactionStatePurchasing:
                [[ITTActivityIndicator currentIndicator] displayMessage:@"连接App Store..."];
                break;
            case SKPaymentTransactionStatePurchased:
                [self completeTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:
                [self failedTransaction:transaction];
                break;
            case SKPaymentTransactionStateRestored:
                [self restoreTransaction:transaction];
                break;
            default:
                break;
        }
    }
}
另外：如何恢复产品，其实已经得到了，这里再详细描述下：
首先向AppStore请求恢复交易：
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
