如何在iOS上检测设备IP地址变化？

Question

Is this even possible? I couldn't find code on how to do it. When not on Wi-Fi, the device IP keeps changing, & I need to keep track of that.

Answer 1

You can use Rechability and schedule some timer to check whether any change occurred. It will looks like that and this .

For retrieving IP address you can try this code .

If possible test with a real device not a simulator as it probably will not be working properly on the simulator (once I tested sth similar and it failed on the simulator while worked perfectly fine on the real devices).

Answer 2

不确定是否可以直接使用，但使用Reachability来捕获每个网络重新连接，每次都可以获得新的ip。
