nsurlconnection

I am using this code... Reachability *r = [Reachability reachabilityWithHostName:@"www.maxqdata.com"]; NetworkStatus internetStatus = [r currentReachabilityStatus]; if ((internetStatus != ReachableViaWiFi) && (internetStatus != ReachableViaWWAN)) { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"No Internet Connection" message:@"You require an internet connection via WiFi or cellular network for location finding to work." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [myAlert show]; [myAlert release]; } from this thread http://www.iphonedevsdk.com/forum/iphone-sdk

Closed . This question is opinion-based . It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post . Closed last year . My last release of application which is 12.8 is rejected by apple saying that i have to add the IPv6 support to the app, I read and reviewed the recommended apple doc named Supporting IPv6 DNS64/NAT64 Networks thoroughly and came to know that already i am using the NSURLConnection class for network connectivity which is mentioned in the same doc, you can see the image from doc

I'm trying to clean up some existing code that downloads a large file from a server in chunks, checks the checksum on each 50 packets, then stitches them together. I'm having some trouble to see if it's the most efficient way as right now it crashes some time because of memory issues. If I don't have the checksum, it does not seem to crash, but I would prefer if I could check my files first. @property (nonatomic, retain) NSMutableData * ReceivedData; - (void)connectionDidFinishLoading:(NSURLConnection *)connection { NSData *sequencePacketData = [[NSData alloc] initWithData:self.ReceivedData];
