如何获取网络更改通知（连接，断开连接，更改）(How to get notifications for Network change(Connect,Disconnect,Change))

在我的应用程序中，我必须在网络发生变化时发出警报，例如当应用程序连接或断开连接或更改（wifi到数据）网络时。

但通过达到网址找到它似乎很昂贵。

iOS中是否有可用的公共API来执行此操作。

In my app I have to alert whenever a network change happens for example when a app is connected or disconnected or changed(wifi to data) network.

But finding it by reaching a url seems expensive.

Is there any public api available in iOS to do this.
