How to check internet connection on iOS device? [duplicate]

Answer 1

Try This to check internet connected or not

NSURL *url = [NSURL URLWithString:@"http://www.appleiphonecell.com/"];
NSMutableURLRequest *headRequest = [NSMutableURLRequest requestWithURL:url];
headRequest.HTTPMethod = @"HEAD";

NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration ephemeralSessionConfiguration];
defaultConfigObject.timeoutIntervalForResource = 10.0;
defaultConfigObject.requestCachePolicy = NSURLRequestReloadIgnoringLocalAndRemoteCacheData;

NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration:defaultConfigObject delegate:nil delegateQueue: [NSOperationQueue mainQueue]];

NSURLSessionDataTask *dataTask = [defaultSession dataTaskWithRequest:headRequest
                                                   completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
                                  {
                                      if (!error && response)
                                      {
                                          block([(NSHTTPURLResponse *)response statusCode] == 200);
                                      }else{
                                          block(FALSE);
                                      }
                                  }];
[dataTask resume];

Answer 2

it's simple , you can use following method to check internet connection .

-(BOOL)IsConnectionAvailable
{
    Reachability *reachability = [Reachability reachabilityForInternetConnection];

    NetworkStatus networkStatus = [reachability currentReachabilityStatus];

    return !(networkStatus == NotReachable);    
}

Answer 3

Reachability* reachability = [Reachability reachabilityWithHostName:@"www.google.com"];
NetworkStatus internetStatus = [reachability currentReachabilityStatus];

 if(remoteHostStatus == ReachableViaWWAN || remoteHostStatus == ReachableViaWiFi)

{


     //my web-dependent code
}
else {
    //there-is-no-connection warning
}

Answer 4

Using Alamofire library:

let reachabilityManager = NetworkReachabilityManager()
let isReachable = reachabilityManager.isReachable

if (isReachable) {
    //Has internet
}else{
    //No internet
}
