Question

我发现从Xcode启动时，安装和使用自定义键盘对我的应用程序运行正常，但如果我将其发布到TestFlight或AppStore，那么当用户点击文本框并尝试调出键盘时它会崩溃。据我所知，我的应用程序中的任何文本框都没有什么特别之处。堆栈跟踪是：

查看实时设备控制台，我看到以下消息：

从堆栈跟踪中可以看出，您使用UIAppearance个代理来设置应用程序的外观。

iOS扩展的一个有趣的怪癖是，使用此API在其他应用程序中进行的自定义实际上会传递给应用程序中包含的扩展（至少在键盘扩展的情况下）。

为确保安全性，所有传递的对象必须使用NSSecureCoding进行编码，因此要求您在UIAppearance中使用的任何对象必须符合此协议（并实际履行其承诺），只要用户是在您的应用中使用键盘扩展程序。

在这种情况下，您的应用似乎正在尝试传递无法归档的颜色。也许您使用+[UIColor colorWithPatternImage:]将图像用作颜色，这符合错误 - 图像可能没有UIColor意义上的颜色。

我建议您审核应用程序的代码，以查看使用UIAppearance设置颜色的任何实例，尤其是在使用colorWithPatternedImage:这样的异域调用时，并删除它们。也许调整all UIAppearance调用no-ops，在TestFlight中推送内部测试版，并查看问题是否已解决，以确认这是问题所在。

无论是哪一个：向Apple提交一个错误。应用程序不应该因为他们无法正确编码UIAppearance而崩溃，尤其是在做一些坦白地说是不受欢迎的事情时。

编辑：可以在不使用TestFlight的情况下重现此问题，同时在release中运行应用（您可以通过转到product-＆gt; scheme-＆gt;编辑方案来启用此功能），方法是添加一行代码将UIButton的背景颜色设置为图案颜色的UIColor，然后调用键盘扩展名。

自定义键盘在App Store中崩溃，但在从Xcode启动时却没有
