IOS obtains network information, including its own IP address and route address.

Recently, I encountered a problem when obtaining the Route IP address. On the iPhone, we can see the gateway address from the settings, but the IOS official does not provide an interface to obtain the gateway address.

Finally made the demo, has uploaded to GitHub, address: https://github.com/ygweric/IOS-RouteAddress

However, the problem is that only the IP address in the range of 192.168.x.x can be obtained, which is difficult to solve for other network segments. If a friend knows that he wants to leave a message ^_^.

The final output result is:
