客户已经为我带来了一个现有的应用程序，我们刚刚发布了一个新版本，包括用于崩溃报告的Crittercism。
自发布以来，我们收到了大量崩溃报告，如下所示。我认为崩溃是由SKProductRequest的代表太快发布造成的，所以我不是在寻找崩溃发生原因的答案 - 这已经在StackOverflow的其他地方得到了解答。
我的问题是我无法复制这个错误。我尝试了很多设备和不同版本的iOS。从Crittercism来看，崩溃发生在主要是最新设备，以及一系列iPhone，iPod和iPad上 - 所以它不是一种特定类型的设备，但我仍然无法实现。我已经下载了Lite版本，并从那里购买了完整版本 - 它完美无缺。
因此，我的问题是，是否有人知道如何在我的设备上实现它以便我可以修复它？！

答案 0 :(得分：1)
Whisk，你在这里发布了一些非常值得怀疑的代码。首先，您使用SYNTHESIZE_SINGLETON_FOR_CLASS（），这意味着您的AppStoreService dealloc方法将永远不会被调用，因此您的应用程序中存在内存泄漏。此外，对productsRequest中的[request release]的调用看起来确实非常奇怪。但是，您对SKProductsRequest的具体问题似乎与指向SKProductsRequest调用回调之前释放的一个对象的委托相关。这表示当充当委托的对象调用其dealloc方法时，您需要将委托设置为nil。至于如何重现问题，这个问题听起来很棘手，因为你在代码中设置了非常奇怪的对象生命周期。我建议您使用自动回归测试工具，但我不确定它是否会因为您使用单例而检查应用中的对象生命周期。见What is so bad about singletons?
答案 1 :(得分：1)
我认为你的理论“即太快发布SKProductRequest的代表”可能是正确的。您是否尝试在购买过程中退出/终止该应用程序？ （如果沙箱服务器速度太快（哈哈！那将是当天），请尝试在事务完成之前插入一些断点并手动终止应用程序。）当您的应用程序再次启动并最终将StoreKit注册为事务时委托，它将获得以前运行的开放交易，发现了一些设计错误，并帮助我们修复了StoreKit交易完成的一类错误。
