我最近向 App Store 提交了一个应用程序。客户在尝试购买应用内购买（或任何与此相关的）时报告了崩溃；但不幸的是，我无法在开发版本中复制它。这是崩溃日志：
https://www.dropbox.com/s/ml9xvb1pk7hxtiu/memejump.crash
使用 xcode 5. 编译器可能有问题吗？
编辑：
是的，所有 Iap 都已提交，我想我知道为什么会出现崩溃。我有一个庞大、复杂且不可靠的 if 语句系列，检查请求是为了购买还是只是为了获取价格，以便不会弹出警报视图。一定有什么问题，但我找不到它......有谁知道一种方法来检查它是购买还是只是请求获得展示价格？我很快就会用象征性的崩溃来摆出代码。
