Steps I followed 1) Added system configuration frame work and imported #import "systemconfiguration/scnetworkreachability.h" and then added below code for checking connectivity
BOOL hasLeadingNumberInString(NSString* s) {
if(s)
return [s length] && isnumber([s characterAtIndex:0]);
else
return NO;
}
-(BOOL)networkConnected: (NSString *)ipAdress {
SCNetworkReachabilityFlags flags = 0;
SCNetworkReachabilityRef netReachability;
BOOL retrievedFlags = NO;
// added the "if" and first part of if statement
//
if (hasLeadingNumberInString(ipAdress)) {
struct sockaddr_in the_addr;
memset((void *)&the_addr, 0, sizeof(the_addr));
the_addr.sin_family = AF_INET;
the_addr.sin_len = sizeof(the_addr);
const char* server_addr = [ipAdress UTF8String];
unsigned long ip_addr = inet_addr(server_addr);
the_addr.sin_addr.s_addr = ip_addr;
netReachability = SCNetworkReachabilityCreateWithAddress(NULL, (struct sockaddr*)&the_addr);
} else {
netReachability = SCNetworkReachabilityCreateWithName(NULL, [ipAdress UTF8String]);
}
if (netReachability) {
retrievedFlags = SCNetworkReachabilityGetFlags(netReachability, &flags);
CFRelease(netReachability);
}
if (!retrievedFlags || !flags) {
return NO;
}
return YES;
}
- (void)checkconnectivity
{
if([self networkConnected:@"192.168.2.10" ])
NSLog(@"Connected");
else
NSLog(@"Not Connected");
}
For god sake it always returns connected.
method 2 i followed, I added AFnetworking using cocopods.I imported "AFNetworkReachabilityManager.h" file and used managerforaddress, it always returns unknown
AFNetworkReachabilityManager *addressCheck=[AFNetworkReachabilityManager managerForAddress:@"192.168.3.10"];
[addressCheck startMonitoring];
[addressCheck setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));
}];
NSLog(@"%hhd",addressCheck.reachable);
NSLog(@"%hhd",[addressCheck isReachable]);
NSString *str=[[NSString alloc]initWithString:[addressCheck localizedNetworkReachabilityStatusString]];
NSLog(@"%@",str);
NSLog(@"%@",addressCheck.localizedNetworkReachabilityStatusString);
}
Even in this way I am unable to get connectivity for particular address. Is there any way to get this or it's not possible.
