ios - 仅限生产版本的 EXC_BREAKPOINT (SIGTRAP)

Question

我的 iOS 应用程序在测试中运行良好，但在启动时崩溃，并使用从 App Store 下载的发布版本。我已经尝试使用 Xcode 中的发布构建配置重新测试并且它没有崩溃，只是商店版本。我很确定它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读取日志而无法缩小范围。设备日志显示如下:

Exception Codes: 0x0000000000000001, 0x00000000e7ffdefe

有什么方法可以让我从商店测试生产版本，或者这个日志是否提供了足够的信息来查明我的错误所在？

Answer 1

几周前我遇到了同样的问题，无法测试它真是令人沮丧。我所做的虽然不是完美的解决方案，但确实让我能够测试这个问题。

进入项目的build设置，然后向下到签名。 Code Signing Identity 下的所有字段都应显示为“iOS Developer”。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 了解发生了什么。

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。
