Check if active internet available or not ios

Question

I am using Reachability but its showing device is connected through wifi or cellular data. I just want if device is connected to internet or not. I just used some code, its working fine but app is getting freez if device not connected to internet.

struct hostent*hostinfo;
char*hostname="google.com";
hostinfo=gethostbyname(hostname);
if (hostinfo == NULL){
NSLog(@"-> no connection!\n");
}

@PrashantTukadiya thanks for your response, i already tried using hostname also its showing same like connected using wifi or data. — Naveen Reddy, May 13 '19 at 13:35
let me give you an example, i just connected using wifi but the net is not working. In that case also i am getting true. — Naveen Reddy, May 13 '19 at 13:36
I am getting timeout errors in that case, but i just want to put a check. — Naveen Reddy, May 13 '19 at 13:38

Could you please look into the question, actually using reachability we can get to know that how we connected. — Naveen Reddy, May 13 '19 at 13:42
Can you do this `if ([[Reachability reachabilityForInternetConnection]currentReachabilityStatus]==NotReachable)` — Prashant Tukadiya, May 13 '19 at 13:43
or `Reachability* reach = [Reachability reachabilityWithHostname:@"www.google.com"];` see this https://github.com/tonymillion/Reachability — Prashant Tukadiya, May 13 '19 at 13:44
Yeah, i tried that. I just enable the hotspot in my mobile and i just switch off the mobile data. In that case also i am getting Reachable via wifi. — Naveen Reddy, May 13 '19 at 13:59

Only Swift

You need to import SystemConfiguration.CaptiveNetwork and bellow method works like charm for me

public class func isInternetAvailable() -> Bool {
    var zeroAddress        = sockaddr_in()
    zeroAddress.sin_len    = UInt8(MemoryLayout<sockaddr_in>.size)
    zeroAddress.sin_family = sa_family_t(AF_INET)

    guard let defaultRouteReachability = withUnsafePointer(to: &zeroAddress, {
        $0.withMemoryRebound(to: sockaddr.self, capacity: 1) {
            SCNetworkReachabilityCreateWithAddress(nil, $0)
        }
    }) else {
        return false
    }

    var flags: SCNetworkReachabilityFlags = []
    if !SCNetworkReachabilityGetFlags(defaultRouteReachability, &flags) {
        return false
    }

    let isReachable = flags.contains(.reachable)
    let needsConnection = flags.contains(.connectionRequired)

    return (isReachable && !needsConnection)
}

I am looking in objective c – Naveen Reddy May 13 '19 at 14:06 — Naveen Reddy, May 13 '19 at 14:06

Use NSURL for check internet connection

NSURL *url = [NSURL URLWithString:@"https://www.google.com/"];
if ([NSData dataWithContentsOfURL:url]) {
    NSLog(@"Device is connected to the Internet");
} else {
    NSLog(@"Device is not connected to the Internet");
}

Check if active internet available or not ios
