Question

我已将图像文件（png）添加到我的项目中。编译我的应用程序，它都工作。现在我删除了图像文件，清理了构建目标并再次编译。一切都编译但应用程序无法启动。我只看到码头上的跳跃图标。 Xcode说：

__TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION__

任何人都可以帮助我吗？感谢。

这是调试器所说的（是的，应用程序被称为'我的PC LOAD LETTER'）：

我一直有删除图像/声音/等文件的问题。也在Visual Studio中。

我使用图像的文件名作为tabview选项卡的标识符，这是UKPrefsPanel的tabView插座。

Answer 1

检查以确保您没有在代码中的任何位置引用该文件（或Info.plist）。

Answer 2

如果您放回PNG，它是否会编译并再次运行？如果没有，那么清除构建环境会有点过多。

<小时/> 啊，Q中有更多评论，所以A中有更多文字...

“超出界限（2）的索引（3）”表明存在索引问题。你有没有把这个索引值硬编码？或者将索引值存储在配置文件中？我可以想象你有例如存储的文件列表和通过删除PNG，此列表变为一个较小的项目，但索引可能不会反映这一点，因此它仍然引用项目3，它不再存在。检查您使用数组的位置的代码，并确保索引始终在此数组的范围内。当超出范围但不依赖代码来自行检查时，提出自定义异常。（换句话说，应用防御性编程。）
