Wifi strength in iPhone app

Question

Does anyone have some code I can use in an iPhone app that will let me see strength of wifi? I have a connection intensive operation and prefer they aren\'t in a spotty zone

Answer 1

I doubt this is possible.

iOS and its SDK isolate applications from doing (and querying) most system-level things. What you could do is to use [NSData dataWithContentsFromURL:...] to do one or two HTTP requests to ensure that the connection is stable and then do the main data transfers.

Answer 2

I wanted to point those of you who land here to a great reference on this question.

Getting the wifi signal for your use on an iOS device:

Accessing & Using the MobileWiFi.framework

Answer 3

This may help get you going on the right track .....
