我的 iOS 应用在测试中运行良好，但在使用从 App Store 下载的发布版本时启动时崩溃。我尝试使用 Xcode 中的发布构建配置重新测试，它不会崩溃，只是商店版本。我很确定这与应用内购买产品加载有关，但由于无法在测试环境中复制它并且无法阅读日志，因此无法缩小范围。设备日志显示如下:

有什么方法可以让我从商店测试生产版本，或者此日志是否提供了足够的信息来查明我的错误在哪里？
几周前我遇到了同样的问题，无法对其进行测试非常令人沮丧。我所做的虽然不是一个完美的解决方案，但确实让我能够测试这个问题。
进入您项目的build设置，然后进入签名。代码签名身份下的所有字段都应显示“iOS 开发人员”。将它们全部更改为 iOS Distribution。构建并运行您的应用程序，它应该会崩溃。现在，您将能够通过 Xcode 弄清楚发生了什么。
此外，一旦您解决了问题，请确保将这些代码签名身份恢复正常。
关于ios - 仅限生产版本的 EXC_BREAKPOINT (SIGTRAP)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39546949/
