Question

嘿，所以我使用了https://gist.github.com/darkseed/1182373中找到的与弧兼容的Reachability标头，由于某种原因，我的代码现在抛出一个＆＃34; Apple Mach-O链接器错误＆＃34;当我为iPhone 6.1和iPad 6.1模拟器编译它时。该项目编译了我们在其上测试过的所有设备（iPad，iPhone 4，iPhone 3和iPhone 5），但出于某种原因在模拟器上失败了。它似乎与新添加的可达性.h和.m文件有关，这是编译器日志。

Answer 1

由于某种原因，您的项目没有所需的框架。 可达性类需要执行SystemConfiguration.framework。

Answer 2

该错误通常意味着您添加了一些需要尚未添加到项目中的特定框架的代码。
