我目前正在尝试在iOS应用上测试应用内购买，但我不确定我是否已正确完成实施，因为当我在iOS设备上测试时，只要我点击购买产品，应用就会崩溃。这是我的代码：

这是我在游戏中点击应用内商品时登录xcode：

PS：我还需要在xcode中为IAP处理添加任何swift类，如果是的话，我该怎么做这个Libgdx项目。
您的应用程序崩溃因为抛出异常 - Store.java的第70行：
throw new GdxRuntimeException(e);
您是否正确设置了所有应用内购买？以下是有关如何使用测试用户测试您的应用内购买的信息：https://support.magplus.com/hc/en-us/articles/203809008-iOS-How-to-Test-In-App-Purchases-in-Your-App
并且不需要添加任何swift类
