Uitableview 在设备中运行时，在展开可选值时意外发现nil

好吧，在模拟器中调试应用程序工作正常，但在使用设备（iPhone）运行时，它会显示类似错误的错误

致命错误：在展开可选值时意外发现nil

许多情况都会导致在展开时发现nil，如果您不了解可选值，我强烈建议您阅读文档中的相关内容

据我所知，您至少使用了3个隐式展开的选项（这可以通过！在某些变量之后看到），它们都遵循“UIImage”

我假设此错误可能是由于UIImage“Dot2”（或其他图像之一）在项目中不存在，或命名不正确所致

如果不是这样的话，那么您真的需要添加一些断点，并尝试隔离发生此错误的代码行，正如前面所说的，许多情况可能会导致可选的查找nil

当您尝试在“indexPath”处访问对象时，newsloglbl发现为零，似乎您的indexPath可能大于newsloglbl的大小，因此当尝试在该路径访问对象时，它什么也找不到，但失败了。如果您需要更详细的帮助，请提供newloglbl的一些代码

您应该提供更多信息，例如发生在哪里、更多的崩溃日志等。如果没有这些信息，就不可能知道发生了什么。嘿@Antonio我编辑了ans，您现在能帮我吗？您有发生错误的代码行吗？如果没有，您能否设置一个断点并单步执行代码来解决这个问题？Desclable.text=（newsloglbl[indexPath.row]as NSString）-在这一行中出现错误OK-为了清楚起见，您应该在问题中报告这一点
