IOHIDFamily的神秘控制台错误

Question

对于我的一个项目,每次在iOS模拟器中运行构建时,Xcode控制台中都会出现此错误消息.它已经发生了一年多,我认为它最终会消失Xcode的更新.我已经取消引用并重新链接了所有的框架,我没有明确地从IOHIDFamily中调用任何内容,无论是什么!它似乎并没有影响我的程序执行,但我真的想弄清楚为什么它每次都会转储所有这些.

Answer 1

当部署到真正的iOS设备时,您正在构建ARM体系结构,在部署到iOS模拟器时,您正在为x386体系结构构建.

在后一种情况下,您的应用程序链接到Mac上存在的mach-o文件(除非有人建议您只链接SDK程序集,而不是本机Mac程序集,但这实际上会降低您的构建速度,并且不再是可用选项)最近的Xcode版本我相信).

显然,其中一个mach-o文件--IOHIDFamily扩展文件,如果将GameKit.framework链接为库,似乎是链接的 - 不是专门为iOS模拟器构建的.因此,消息.据我所知,这是一个确认的Apple漏洞,并且将在某些时候由Apple修复.

这只是iOS模拟器的问题,可以安全地忽略.

Vinnie发布了这个解决方案

尝试将IOS构建选项:链接器选项设置为"仅链接SDK程序集",为我修复它
