RealReachability

RealReachability is based on Apple's Reachability code

Apple's Reachability will not actually test if the host reachable or not. It only does the host name translation(if what is given is a host name ) and check if the package can leave NIC

RealReachability takes an URL for testing the actual reachability of the given host. It does async reachability check but it also privoe a method for you to do sync reachability check if the current status is pending. Real reachability status change notifcation would be delivered to main thread.

Usage:

BOOL (^verifyBlock)(NSData* data) = ^BOOL(NSData* data){
    NSError* error;
    NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:(NSJSONReadingMutableContainers) error:&error];
    if(error)
        return NO;
    else{
        NSLog(@"%@", [dict description]);
        NSString* status = [dict objectForKey:@"status"];
        if([status isEqualToString:@"GOOD"]){
            return YES;
        }else{
            return NO;
        }
    }
};

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reachabilityChanged:) name:kInternetStatusChangedNotification object:nil];
NSString *remoteURL = @"https://b4.autodesk.com/api/system/v1/health.json?detailed=0";
self.hostReachability = [[RLReachability alloc] initWithGetURL:remoteURL VerificationHandler:verifyBlock];
