How to use reachability class to detect valid internet connection?

Question

I\'m new to iOS development and am struggling to get the reachability.h class to work. Here is my code for view controller:

- (void)viewWillAppear:(BOOL)anim         


        

Answer 1

just Import Reachability classes and after that

-(BOOL) connectedToNetwork
 {
const char *host_name = "www.google.com";
  BOOL _isDataSourceAvailable = NO;
Boolean success;
SCNetworkReachabilityRef reachability = SCNetworkReachabilityCreateWithName(NULL,host_name);
SCNetworkReachabilityFlags flags;
success = SCNetworkReachabilityGetFlags(reachability, &flags);
_isDataSourceAvailable = success &&
(flags & kSCNetworkFlagsReachable) &&
!(flags & kSCNetworkFlagsConnectionRequired);

CFRelease(reachability);

return _isDataSourceAvailable;
}
