Wrapper for SCNetworkReachability methods of SystemConfiguration.framework

Network reachability for iOS

---

About

SCNetworkReachability class is the wrapper on C-structures and C-functions of SCNetworkReachability API in SystemConfiguration.framework

Installation

1. Installing with cocoa pods

Add to Podfile pod 'SCNetworkReachability' And run command pod install

2. Add as git submodule

cd <project source directory>
git submodule add https://github.com/belkevich/reachability-ios.git <submodules directory>

Then add files to your XCode project. And add SystemConfiguration.framework to your Target -> Build phases -> Link Binary With Libraries

Using

Check internet connection now

SCNetworkReachability *reachability = [[SCNetworkReachability alloc] initWithHostName:@"www.apple.com"];
if (reachability.status == SCNetworkStatusNotReachable)
{
	// no internet connection
} 
else
{
	// do network connection
}

Check is connection Wi-Fi or Cellular

SCNetworkReachability *reachability = [[SCNetworkReachability alloc] initWithHostName:@"www.apple.com"];
if (reachability.status == SCNetworkStatusViaCellular)
{
	// internet connection via cellular
} 
else if (reachability.status == SCNetworkStatusViaWiFi)
{
	// internet connection via Wi-Fi 
}

Check is connection status changed

Class that will be check changes should implement SCNetworkReachabilityDelegate protocol methods:

@protocol SCNetworkReachabilityDelegate <NSObject>

@required
- (void)reachabilityDidChange:(SCNetworkReachability *)reachability;

@optional
- (void)reachability:(SCNetworkReachability *)reachability didFail:(NSError *)error;

@end

And set reachability instance delegate to self

SCNetworkReachability *reachability = [[SCNetworkReachability alloc] initWithHostName:@"www.apple.com"];
reachability.delegate = self;
