SCNetworkReachabilityKit provides Objective-C developers with wrappers for the network reachability API found in the Apple's System Configuration framework.
SCNetworkReachabilityKit provides a multi-platform thread-aware network reachability toolkit for Apple platforms. The basic problem: Apple's SystemConfiguration framework currently provides an entirely C-based synchronous API.
SCNetworkReachabilityKit incorporates two targets: an OS X framework and an iOS static library.
Detailed instructions on how to use the SCNetworkReachabilityKit and link it with iOS apps are available HERE.
