Re: iOS Reachability

There are much newer versions of this. Check on Apple’s sample files and on Github. Stay away from the old copy that you have.

Hi,

A while back I included some code from a sample project that setup Game Center/Kit. This code used a Class called “ Reachability”:

From looking at the code it looks quite old and I’m not sure how “right” it is. Is there another version of “Reachability” that I should be using?


When I Compile/Analyse the project, I get warnings on these statements:

+(Reachability*)reachabilityWithHostname:(NSString*)hostname
{
SCNetworkReachabilityRef ref = SCNetworkReachabilityCreateWithName(NULL, [hostname UTF8String]);
if (ref)
{
id reachability = [[self alloc] initWithReachabilityRef:ref]; //**********************Potential Leak

#if __has_feature(objc_arc)
return reachability;
#else
return [reachability autorelease];
#endif

}


+(Reachability *)reachabilityWithAddress:(const struct sockaddr_in *)hostAddress
{
SCNetworkReachabilityRef ref = SCNetworkReachabilityCreateWithAddress(kCFAllocatorDefault, (const struct sockaddr*)hostAddress);
if (ref)
{
id reachability = [[self alloc] initWithReachabilityRef:ref]; //**********************Potential Leak

#if __has_feature(objc_arc)
return reachability;
#else
return [reachability autorelease];
#endif
}

return nil;
}
