使用UIActivityViewController分享功能时控制台报错求助

我用翻译工具沟通，正在用UIActivityViewController开发图文分享功能，运行时控制台出现了一些我认为不该出现的错误日志，附上相关代码，想知道报错原因。

控制台错误日志 #

ac.excludedActivityTypes = [.assignToContact, .copyToPasteboard]
present(ac, animated: true)

报错原因分析 #

这些错误属于iOS系统内部服务调用时的权限/沙箱限制日志，和你的业务代码逻辑无关，具体原因如下：

• RBSServiceErrorDomain相关错误：RunningBoard是iOS负责管理进程生命周期、断言的系统服务，错误中提到的com.apple.runningboard.process-state等权限是系统级权限，仅开放给苹果官方App或特殊授权应用，第三方App无法获取。这类错误是系统内部调用时的权限校验失败，不会影响你的分享功能正常运行。
• NSCocoaErrorDomain 4099错误：是App沙箱限制导致无法访问com.apple.mobile.usermanagerd.xpc系统服务，属于系统层面的冗余日志输出，同样不影响分享功能的执行。
• 结论：你的代码逻辑没有问题，这些错误可以完全忽略，不会导致分享功能失效。
