问题 For a GPS tracking app, recording location signals with WIFI turned on results in really imprecise data or data with gaps. I've used the Reachability queries to detect if wifi is available prior to starting tracking. The problem is that if when that query is made the wifi is enabled but not connected to a network, it shows that the internet is not reachable via wifi, but that's not an indication of if the setting is disabled in the settings app. This means that if the user starts running and

Reachability vs UIDevice-Reachability

问题 I need to test network reachability in my iPhone project. Which project is better to use? Reachability vs UIDevice-Reachability 回答1: Reachability if your only issue is to test network reachability. It's apple sample code and it's pretty easy to use. UIDevice is great for learning but a bit overkill just for network reachability. So in the end either of them will do. Depends on what you want to do. 来源： https://stackoverflow.com/questions/4954904/reachability-vs-uidevice-reachability
