Hi
I've searched but can't see a similar question.
I've added a method to check for an internet connection per the Reachability example. It works most of the time, but when installed on the iPhone, it quite often fails even when I do have internet connectivity (only when on 3G/EDGE - WiFi is OK).
Basically the code below returns NO.
If I switch to another app, say Mail or Safari, and connect, then switch back to the app, then the code says the internet is reachable. Kinda seems like it needs a 'nudge'.
Anyone seen this before? Any ideas?
Many thanks
James
+ (BOOL) doWeHaveInternetConnection{
BOOL success;
// google should always be up right?!
const char *host_name = [@"google.com" cStringUsingEncoding:NSASCIIStringEncoding];
SCNetworkReachabilityRef reachability = SCNetworkReachabilityCreateWithName(NULL,
host_name);
SCNetworkReachabilityFlags flags;
success = SCNetworkReachabilityGetFlags(reachability, &flags);
BOOL isAvailable = success && (flags & kSCNetworkFlagsReachable) && !(flags & kSCNetworkFlagsConnectionRequired);
if (isAvailable) {
NSLog(@"Google is reachable: %d", flags);
}else{
NSLog(@"Google is unreachable");
}
return isAvailable;
}
