测试应用内购买时出现“lldb”错误

Question

请耐心等待。这是我第一次设置应用内购买，我会尽力提供尽可能多的信息。我最终没有为其他人的代码整理互联网，而是购买了一个无限技能课程，专门介绍如何将非续订订阅应用内购买添加到我的应用程序。他们的课已经过时了，后来发现，“跟随”项目文件没有下载。所以我做了很多研究，这就是我想出的：

1. 我在 iTunes 中创建了一个应用内购买，应用内标识符与我的 .m 编码中的标识符匹配。

2. 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。

3. 我创建了一个视图控制器，添加了按钮，并为子类使用了 SKStoreProductViewController。该视图控制器如下所示：

4. 我导入了 storekit 和 SK 代表。

当我从主视图中点击标签栏按钮以将我带到应用内视图控制器时，它会崩溃。

最后是编码： InAppViewController.h：

#import <StoreKit/StoreKit.h>

@interface InAppViewController : SKStoreProductViewController

@end

InAppViewController.m：

请理解这是我第一次尝试这个。对我来说，可能看起来很愚蠢的仍然是学习阶段。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 Exceptions 断点。
