我在tonymillion Reachability类中得到了这个链接错误。我正在使用它来获取我的ios应用程序中的互联网连接。有人告诉我为什么会出现这个错误。

添加SystemConfiguration Framework并将Deployment Target更改为IOS 6.0解决了我的问题。

1）添加SystemConfiguration Framework：选择您的项目，然后选择您的目标（手机/平板电脑），然后选择Build Phases

有一个名为Link Binary的块与Libraries，在它的末尾有+符号点击。它将打开一个对话框，在其中搜索系统配置，然后单击“确定/添加”。

2）更改部署目标：选择您的项目，然后选择目标（移动设备/平板电脑），然后选择构建设置。

存在部署块，然后是IOS部署目标，将其更改为IOS 6.0或更高版本。

希望这会有所帮助
