    <p>I need some help in IOS Socket programming. I have implemented a successful TCP Socket connection between IOS and a Java Server, however I found that it is imposible to reconnect it after the socket fails (I disconnect my network and reconnect it). </p> <p>That's the code I use to open the streams:</p> <pre><code>- (void)initCommunication{ @try { CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"XXX.XXX.XXX.XXX", 4454, &amp;readStream, &amp;writeStream); inputStream = (__bridge NSInputStream *)readStream; outputStream = (__bridge NSOutputStream *)writeStream; //Asignamos los delegates inputStream.delegate = self; outputStream.delegate = self; [inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [inputStream open]; [outputStream open]; connected = true; } } @catch (NSException *exception) { connected = false; NSLog(@"Error connecting socket: %@", exception.reason); [self checkConnection]; } } </code></pre> <p>And when I receive a NSStreamEventErrorOccurred or a NSStreamEventEndEncountered I try to close the connection and reconnect again.</p> <p>I close it with:</p> <pre><code>-(void) close{ [inputStream close]; [inputStream removeFromRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [outputStream close]; [outputStream removeFromRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [inputStream setDelegate:nil]; inputStream = nil; [outputStream setDelegate:nil]; outputStream = nil; connected = false; } </code></pre> <p>The problem is that the socket is not reconnecting again... I am thinking on using SmallSockets or CocoaAsyncSockets to see if I can reconnect the socket... Do you see any implementation problem? Do you recommend using SmallSockets or CocoaAsyncSockets??</p> <p>Thank you in advance!!</p>

    1. COWhat error do you get on reconnect? Also, are you sure that the server is listening properly (e.g., can you connect to it with netcat from your Mac, disconnect, and immediately reconnect)?

    3. COYes I am using ARC, that's why there are no releases on my code... however I receive everything ok on the Server part, so I can exchange packets between both parts...the problem come when I try to reconnect when I force a disconnect... I have been able to send again but not to receive. I will put some more information about the sockets events I receive...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
