"lldb" 测试应用内购买时出错

Question

请耐心等待。这是我第一次设置应用内购买，我会尝试提供尽可能多的信息。我没有为别人的代码整理互联网，而是从无限技能中购买了 class，专门关于如何将非续订订阅应用内购买添加到我的应用程序。他们的class已经过时了，来看看，"follow along"工程文件没有下载。所以我做了很多研究，这就是我想出的：

我在 iTunes 中创建了应用内购买，应用内标识符与我的 .m 编码中的标识符匹配。
我创建了一个新的配置文件并启用了应用内购买和 icloud 来管理购买的后端。当我返回应用程序时，我启用了 icloud 并确保在项目目标中打开了应用程序内购买。
我创建了一个视图控制器，添加了按钮，对于子class我使用了 SKStoreProductViewController。该视图控制器看起来像这样：
我导入了 storekit 和 SK 代表。

当我从主视图点击 tabbar 按钮将我带到应用程序内视图控制器时，它崩溃了。

最后是编码： InAppViewController.h:

#import <StoreKit/StoreKit.h>

@interface InAppViewController : SKStoreProductViewController

@end

InAppViewController.m:

@implementation InAppViewController

    [super viewDidLoad];
    // Do any additional setup after loading the view.
    _btnBuyAccess.userInteractionEnabled = NO;

    _keyStore = [[NSUbiquitousKeyValueStore alloc] init];




    _expirationDate = [_keyStore objectForKey:@"expirationDate"];
    NSDate *today = [NSDate date];
    if (_expirationDate == nil)
        _expirationDate = today;

    if (_expirationDate > today) {
        _btnPremiumFeature.userInteractionEnabled = YES;
    }
        else {
            _btnBuyAccess.userInteractionEnabled = YES;

            [self getProductInfo];
        }
    }

-(void) getProductInfo{

    if ([SKPaymentQueue canMakePayments])
    {
        NSMutableArray *productIdentifierList = [[NSMutableArray alloc] init];

        [productIdentifierList addObject:[NSString stringWithFormat:@"com.joshua.contractorrich.inapp"]];

                                          SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers: [NSSet setWithArray:productIdentifierList]];

        request.delegate = self;
        [request start];
    }
}

-(void) productsRequest: (SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
    NSArray *products = response.products;

    if (products.count != 0)
    {
        _product = products[0];
        _btnBuyAccess.userInteractionEnabled = YES;
        _lblStatus.text = @"Ready for Purchase!";
    }else{
        _lblStatus.text = @"Product was not Found!";
    }
    products = response.invalidProductIdentifiers;
    for (SKProduct *product in products)
    {
        NSLog(@"Product not found: %@", product);
    }

}



- (IBAction)btnBuyAccessTouched: (id)sender {

    SKPayment *payment = [SKPayment paymentWithProduct:_product];
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}
-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    for (SKPaymentTransaction *transaction in transactions)
    {
        switch (transaction.transactionState) {
            case SKPaymentTransactionStatePurchased:
                _btnPremiumFeature.userInteractionEnabled = YES;
                _lblStatus.text = @"Purchase Completed!";
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;

            case SKPaymentTransactionStateFailed: NSLog(@"Transaction Failed!");
                _lblStatus.text = @"Purchase Failed!";
                [[SKPaymentQueue defaultQueue]
            finishTransaction:transaction];

            default:
                break;
        }
    }
}

-(void) setExpirationDate {
    NSDateComponents *components = [[NSDateComponents alloc] init];
    [components setMonth:3];
    NSDate *expirationDate = [[NSCalendar currentCalendar] dateByAddingComponents:components toDate:[NSDate date] options:0];
    [_keyStore setObject:expirationDate forKey:@"expirationDate"];
    [_keyStore synchronize];
}

-(void) initializeStore {
    [_keyStore setObject:nil forKey:@"expirationDate"];
    [_keyStore synchronize];
}



- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

/*
#pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
}
*/

@end

请理解这是我第一次尝试这个。看起来很愚蠢的东西对我来说仍然是学习阶段。谢谢！

这个故事中没有运行时错误。所发生的只是您创建了一个异常断点。现在你停下来了。只需恢复运行。如果这很麻烦，请禁用异常断点。
