Hi,

If it were for me, I won't use the native URL request in Objective C

Try looking for AFNetworking.

Almost ALL iOS apps runs on it. It handles your timeout session in a block, and it is asynchronous, hence, you can control the timeout block as you like.

Furthermore, if you were to check for slow / no internet, you should not use timeout as a threshold to determine whether 3g/4g/Wifi is available. It is not recommended.

Edit :

You can refer to this.

It maybe due to your POST request, and it was only fixed iOS 6 and above.

Try setting the timeout period higher, maybe to 60~120 seconds, see will it run correctly or not.
