二：代码部分

- (void)viewDidLoad {
    [super viewDidLoad];
    self.title = @"购买页面";
      self.navigationItem.rightBarButtonItem = [self rightBarButtonWithName:NSLocalizedString(@"07-restore", nil) target:self action:@selector(restonreProduct)];
    [self BuildUI];
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
}

#pragma mark -- 购买按钮事件
-(void)buycommodity {

        if ([SKPaymentQueue canMakePayments]) {
            [self RequestProductData];
            //        NSLog(@"允许程序内付费购买");
        }
        else
        {
            //        NSLog(@"不允许程序内付费购买");
            [self MarkToViewString:NSLocalizedString(@"09-noOpenApplications", nil)];
        }
}

-(void)RequestProductData
{
//    NSLog(@"---------请求对应的产品信息------------");
    NSArray *product = nil;
    product=[[NSArray alloc] initWithObjects:ProductID,nil];
    NSSet *nsset = [NSSet setWithArray:product];
    SKProductsRequest *request=[[SKProductsRequest alloc] initWithProductIdentifiers: nsset];
    request.delegate=self;
    [request start];
}

//<SKProductsRequestDelegate> 请求协议
//收到的产品信息
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
//    NSLog(@"-----------收到产品反馈信息--------------");
    NSArray *myProduct = response.products;
    if([myProduct count] == 0){
        [SVProgressHUD dismiss];
//        NSLog(@"--------------没有商品------------------");
        return;
    }
    SKProduct *P = nil;
    for(SKProduct *product in myProduct){
//        NSLog(@"product info");
//        NSLog(@"SKProduct 描述信息%@", [product description]);
//        NSLog(@"产品标题 %@" , product.localizedTitle);
//        NSLog(@"产品描述信息: %@" , product.localizedDescription);
//        NSLog(@"价格: %@" , product.price);
//        NSLog(@"Product id: %@" , product.productIdentifier);
        if ([product.productIdentifier isEqualToString:ProductID]) {
            P = product;
        }
    }
    SKPayment *payment = nil;
    payment = [SKPayment paymentWithProduct:P];
//    NSLog(@"---------发送购买请求------------");
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

//监听购买结果
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transaction{
    
    for(SKPaymentTransaction *tran in transaction){
        
        switch (tran.transactionState) {
            case SKPaymentTransactionStatePurchased:{
//         NSLog(@"交易完成");
              [self checkTransaction:tran];//去验证
            }
                break;
            case SKPaymentTransactionStatePurchasing:
              //  NSLog(@"商品添加进列表");
                break;
            case SKPaymentTransactionStateRestored:{
              //  NSLog(@"已经购买过商品");
                [self restoreTransaction:tran];
            }
                break;
            case SKPaymentTransactionStateFailed:{
             //  NSLog(@"交易失败");
                [[SKPaymentQueue defaultQueue] finishTransaction:tran];
                [SVProgressHUD showErrorWithStatus:@"购买失败"];
            }
                break;
            default:
                break;
        }
    }
}

验证前检查看看是否有未完成订单

#pragma mark --检查本次支付信息，并与本地缓存信息对比，查看是否是未完成订单
- (void)checkTransaction:(SKPaymentTransaction *)transaction{

    NSDictionary *saveDic = [[NSDictionary alloc]init];
    saveDic = [DDKeychain keyChainLoad];
    if (saveDic != nil) {
       //取自支付队列未完成的商品ID去缓存中拿对应的信息.有就去验证
        [self connetServerWithTransactionandPayInfo:transaction];
        return;
    }else{
        //全新的支付
        NSDictionary *newPayInfoDic = @{@"product_id":ProductID,
                                        @"apple_orderid":transaction.transactionIdentifier};
        /** 已Keychain将数据存起来 */
        [self setOrderData:newPayInfoDic key:ProductID];
        /** 服务器验证 */
        [self connetServerWithTransactionandPayInfo:transaction];
    }
}

#pragma mark -- server验证
- (void)connetServerWithTransactionandPayInfo:(SKPaymentTransaction *)transaction{
    //从沙盒中获取交易凭证并且拼接成请求体数据
    NSURL *receiptUrl=[[NSBundle mainBundle] appStoreReceiptURL];
    NSData *receiptData=[NSData dataWithContentsOfURL:receiptUrl];
    NSString *receiptString=[receiptData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];//交易凭证转化为base64字符串
//    /** 商品id 订单号 苹果的订单号 传给 后台（看你们后台要求）*/

    /*
     1.调用服务器接口验证成功一定要删除keyChain存储的数据
     2. [[SKPaymentQueue defaultQueue]finishTransaction:transaction];

     */
}

非消耗商品苹果需要提供恢复购买按钮，在已经购买过商品调用恢复购买处理

#pragma mark -- 恢复购买
- (void)restonreProduct{

    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{
    NSLog(@" 交易恢复处理");
    [self checkTransaction:transaction];//去验证

}

内购基本完成，我项目审核已通过！
