【中文标题】是啥导致了带有强化 xcodebuild（Objective-C）的未知属性属性“类”？

【英文标题】：What causes unknown property attribute 'class' with fortify xcodebuild (Objective-C)?是什么导致了带有强化 xcodebuild（Objective-C）的未知属性属性“类”？

【发布时间】：2017-10-19 17:03:34

【问题描述】：

我有一个想要在其上运行 fortify 的 ios 项目。使用 xcodebuild 构建它可以正常工作并且已经使用了多年。使用 sourceanalyzer xcodebuild 构建它失败。

实际工作的构建命令：

xcodebuild

失败的命令

sourceanalyzer -b MobuyleUniversaliOS -debug-verbose -logfile fortify-build.log xcodebuild

这种情况发生在对 NS* 类的各种引用中，直到最后 sourceanalyzer 放弃并移至具有相同问题的下一个文件。这是错误输出的示例：

【参考方案1】：

'class' 属性在去年中后期（2016 年）的某个时候被添加到 Objective-C。

我的想法是 fortify/sourceanalyzer（我没有使用过）要么不支持该语言功能，要么支持并且您需要更新版本。

【讨论】：

谢谢。我必须通过 IT 和我们的安全部门才能获得新版本。如果/当它修复它时，我会接受这个答案。

@GingerMcMurray 我简要查看了是否有关于 Objective-C fortify 使用的语言版本/规范的文档，但我找不到。我的直觉告诉我这种情况是这样的。祝你好运。
