Here's my objective-c code... I've tried the code that's commented out as well, but no luck. I simply want to get this to connect.
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
//get socket connecting...
NSError *err = nil;
uint16_t thePort = htons(1234);
// struct sockaddr_in ip;
// ip.sin_family = AF_INET;
// ip.sin_port = htons(thePort);
// inet_pton(AF_INET, "192.168.2.5", &ip.sin_addr);
//
// NSData* host = [NSData dataWithBytes:&ip length:ip.sin_len];
//
// if(![self.socket connectToAddress:host error:&err]) {
// NSLog(#"Failed to connect... %#", err);
// }
if(![self.socket connectToHost:#"192.168.2.5" onPort:thePort error:&err]) {
NSLog(#"Failed to connect %#", err);
}
// Do any additional setup after loading the view, typically from a nib.
}
When I run it this is all that I get...
2013-11-02 23:02:10.404 bonfire.alpha0.0[3892:70b] Failed to connect (null)
On the server side I'm using a simple implementation of an echo-server (can be found https://github.com/zappala/python-networking-and-threading/blob/master/echo-server/echoserver.py). I know physical connection between client and server (192.168.2.5) is good because when I run echoclient.py from the client computer it works just fine.
Okay I found the error, very noobish one haha. I wasn't initiating the GCDAsyncSocket properly. Here's the proper code for initiating it.
self.socket = [[GCDAsyncSocket alloc] initWithDelegate:self.sDelegate delegateQueue:dispatch_get_main_queue()];
Related
I'm trying to "send to" and "receive from" on same GCDAsyncSocket object, but it return's error as Attempting to accept while connected or accepting connections. Disconnect first. while trying to initialising the object.
My Code :
-(instancetype)initWithHost:(NSString *)host port:(NSInteger)port userData:(NSDictionary *)userData delegate:(id<AKSenderSocketDelegate>)delegate
{
self = [super init];
if (self)
{
self.delegate = delegate;
self.senderSocket = [[GCDAsyncSocket alloc] initWithDelegate:self delegateQueue:dispatch_get_main_queue()];
self.senderSocket.userData = userData;
NSError *err = nil;
//---- Sender

Please help!!
You're overcooking the pudding (grin). Once you've connected, you're ready to start communicating. There's no need for the accept message.
connectToHost:onPort:error: is like placing a phone call: you call, the other party picks up (because that other party has already made itself available with acceptOnPort:error: or its equivalent). Once the connection is made, you can read and write data over the same socket; sockets are bi-directional.
So if you want to "place a call", use connectToHost:onPort:error:. If instead you want to wait for the other party to place the call, use acceptOnPort:error:. Regardless of which side of the conversation is the "connecter" or the "accepter", both sides of the conversation can both send (write) and listen (read).
I'm trying to setup a listenerSocket on localhost using GCDAsyncSocket for iOS device.
In the socketDidDisconnect delegate I either get error Code=49 for trying with port 0 (which I'm hoping would find the first available free port).
Or if I use a port no then I get error Code=61 for trying to connect with localhost.
- (IBAction)start:(id)sender {
asyncSocket = [[GCDAsyncSocket alloc] initWithDelegate:self delegateQueue:dispatch_get_main_queue()];
NSError *err = nil;
if(![asyncSocket connectToHost:#"localhost" onPort:0 error:&err])
{
NSLog(#"Connect Error: %#", err);
}
}
#pragma mark – delegate
-(void)socketDidDisconnect:(GCDAsyncSocket *)sock withError:(NSError *)err
{
NSLog(#"socketDidDisconnect");
if (err) {
NSLog(#"Socket Error: %#", err);
// Error in connect function:
// NSPOSIXErrorDomain Code=49 "Can't assign requested address" - onPort:0
// NSPOSIXErrorDomain Code=61 "Connection refused" - connectToHost:#"localhost"
}
}
connectToHost will act as the client-side of the connection. You want to read the Writing a server section of the help page:
listenSocket = [[GCDAsyncSocket alloc] initWithDelegate:self delegateQueue:dispatch_get_main_queue()];
NSError *error = nil;
if (![listenSocket acceptOnPort:port error:&error])
{
NSLog(#"I goofed: %#", error);
}
- (void)socket:(GCDAsyncSocket *)sender didAcceptNewSocket:(GCDAsyncSocket *)newSocket
{
// The "sender" parameter is the listenSocket we created.
// The "newSocket" is a new instance of GCDAsyncSocket.
// It represents the accepted incoming client connection.
// Do server stuff with newSocket...
}
However you need to know the port to use (if you let the system decide what port to use then how is a client supposed to know how to connect to the server?). Also the port will almost certainly need to be > 1024 (out of the reserved port range). However I haven't ever tried to create a Server on iOS.
I'm developing an application which is connecting to another device and in order to connect to it my app has to find the IP of it. I'm doing it through UDP socket. I'm sending a message to the server application in the other device and then the server app sends me another message but after I receive it I only use the IP address. Then I want to get it from this .m file to another .m file which is going to make the TCP connection between the two devices. Here's the code I use:
NSString *SearchCommand = #"AT+S";
static int receivedByteCount = 0;
BOOL connectedThroughUDP;
- (void) activate {
connectedThroughUDP = NO;
AsyncUdpSocket *udpSocket = [[AsyncUdpSocket alloc] initWithDelegate:self];
[udpSocket bindToPort:1234 error:nil ];
[udpSocket enableBroadcast:YES error:nil];
NSData* data=[SearchCommand dataUsingEncoding:NSUTF8StringEncoding];
if ([udpSocket sendData:data toHost:#"255.255.255.255" port:30100 withTimeout:3 tag:0])
{
//2 second timeout. onUdpSocket methods will provide results
[udpSocket receiveWithTimeout:2 tag:0];
NSLog(#"Connected.");
}
}
- (BOOL)onUdpSocket:(AsyncUdpSocket *)sock didReceiveData:(NSData *)data withTag:(long)tag fromHost:(NSString *)host port:(UInt16)port{
NSString *receiveddata = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
addressOfServer = host;
NSLog(#"addressOfServer = %#", addressOfServer);
connectedThroughUDP = YES;
return YES;
}
- (NSString *) getHost {
return addressOfServer;
}
- (BOOL) isItConnected {
return connectedThroughUDP;
}
addressOfServer is global variable.
In the Log when I want NSLog(#"addressOfServer = %#", addressOfServer); I receive the IP address which I want but then when I want to access it from the getHost method I receive (null).
I know it will be something very simple but it caused me a real headache in the past 3 hours so I would be very thankful if you can help me!
Are you calling these 3 lines right after each other like so:
UDPConnection *udpConnection = [[UDPConnection alloc] init];
[udpConnection activate];
host = [udpConnection getHost];
If so your issue is that [udpConnection activate]; is going to take some time to connect and figure out the address. You are calling [udpConnection getHost]; too soon.
You will need to setup a delegate or completion block that will be triggered when didReceiveData is fired
Alright, this involves a lot of network coding from this part of a multiplayer tutorial.
Basically, I'm trying to implement a multiplayer game using GameKit as per the tutorial linked above. I put in all of the necessary network coding and more or less understand it, however I've hit a snag somewhere along the line of method calls. Basically, the setup that I have is that one device acts as the host and the rest act as the clients. I have two separate UIViewcontrollers for the host and clients respectively where the connection is established.
Now the thing is, the connection gets established, but it's only the host that recognizes the connection, not the client. The problem is here:
- (void)sendPacketToAllClients:(Packet *)packet
{
[_players enumerateKeysAndObjectsUsingBlock:^(id key, Player *obj, BOOL *stop)
{
obj.receivedResponse = [_session.peerID isEqualToString:obj.peerID];
}];
GKSendDataMode dataMode = GKSendDataReliable;
NSData *data = [packet data];
NSError *error;
if (![_session sendDataToAllPeers:data withDataMode:dataMode error:&error])
{
NSLog(#"Error sending data to clients: %#", error);
}
}
This is implemented in GameMultiplayer, where the actual game will be implemented. What this method is supposed to be doing is sending data packets to each of the clients saying that the host received the connection request and is able to connect with them. After [_session sendDataToAllPeers:data withDataMode:dataMode error:&error] is called (the method in the if statement), this method is supposed to be triggered:
- (void)receiveData:(NSData *)data fromPeer:(NSString *)peerID inSession:(GKSession *)session context:(void *)context
{
#ifdef DEBUG
NSLog(#"Game: receive data from peer: %#, data: %#, length: %d", peerID, data, [data length]);
#endif
Packet *packet = [Packet packetWithData:data];
if (packet == nil)
{
NSLog(#"Invalid packet: %#", data);
return;
}
Player *player = [self playerWithPeerID:peerID];
if (player != nil)
{
player.receivedResponse = YES; // this is the new bit
}
if (self.isServer)
[self serverReceivedPacket:packet fromPlayer:player];
else
[self clientReceivedPacket:packet];
}
This method is in the next part of the tutorial I linked above (which is here) and is supposed to receive the packets that the host sends to all clients and implement the next methods in this networking chain. However, the method never gets called. No debug breakpoints are triggered and I get nothing in the console.
I understand if I need to provide more source material, but there is a lot of network coding already implemented, so I want to keep it down to what people need to see. Also, [_session setDataReceiveHandler:self withContext:nil] and _session.delegate = self are written in another method that is called in GameMultiplayer, so that's not the problem. Does anyone know what I need to fix?
EDIT: As requested, here's where GKSession is initialized:
#property (nonatomic, strong, readonly) GKSession *session; //This is done in the header file
#synthesize session = _session; //This is done in the main file
- (void)startAcceptingConnectionsForSessionID:(NSString *)sessionID
{
if (_serverState == ServerStateIdle)
{
_serverState = ServerStateAcceptingConnections;
_connectedClients = [NSMutableArray arrayWithCapacity:self.maxClients];
_session = [[GKSession alloc] initWithSessionID:sessionID displayName:nil sessionMode:GKSessionModeServer];
_session.delegate = self;
_session.available = YES;
}
}
The session is initialized in MatchmakingServer, which is used in the host view controller. The session is then passed on to the main view controller of the app, which then initializes GameMultiplayer and sends the GKSession to it. Here's where the host view controller sends it to the main view controller:
- (IBAction)startAction:(id)sender
{
if (_matchmakingServer != nil && [_matchmakingServer connectedClientCount] > 0)
{
NSString *name = [self.nameTextField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
if ([name length] == 0)
name = _matchmakingServer.session.displayName;
[_matchmakingServer stopAcceptingConnections];
[self.delegate hostViewController:self startGameWithSession:_matchmakingServer.session playerName:name clients:_matchmakingServer.connectedClients];
}
}
and then the main view controller handles that method call here:
- (void)hostViewController:(MatchmakerHost *)controller startGameWithSession:(GKSession *)session playerName:(NSString *)name clients:(NSArray *)clients
{
[self dismissViewControllerAnimated:NO completion:^
{
[self startGameWithBlock:^(GameMultiplayer *aGame)
{
[aGame startServerGameWithSession:session playerName:name clients:clients];
}];
}];
}
and finally, this is where that method call is implemented in GameMultiplayer:
- (void)startServerGameWithSession:(GKSession *)session playerName:(NSString *)name clients:(NSArray *)clients
{
_clients = clients;
const char* className = class_getName([[_clients objectAtIndex:0] class]);
NSLog(#"yourObject is a: %s", className);
self.isServer = YES;
_session = session;
_session.available = NO;
_session.delegate = self;
[_session setDataReceiveHandler:self withContext:nil];
_state = GameStateWaitingForSignIn;
[self.delegate gameWaitingForClientsReady:self];
// Create the Player object for the server.
Player *player = [[Player alloc] init];
player.name = name;
player.peerID = _session.peerID;
player.position = PlayerPositionBottom;
[_players setObject:player forKey:player.peerID];
// Add a Player object for each client.
int index = 0;
for (NSString *peerID in clients)
{
Player *player = [[Player alloc] init];
player.peerID = peerID;
[_players setObject:player forKey:player.peerID];
if (index == 0)
player.position = ([clients count] == 1) ? PlayerPositionTop : PlayerPositionLeft;
else if (index == 1)
player.position = PlayerPositionTop;
else
player.position = PlayerPositionRight;
index++;
}
NSLog(#"Players:");
Packet *packet = [Packet packetWithType:PacketTypeSignInRequest];
[self sendPacketToAllClients:packet];
// for (int i = 0; i < [_players count]; i++) {
// NSLog([NSString stringWithFormat:#"%#", [clients objectAtIndex:i]]);
// }
}
I think you are calling send to fast. When server realize about connection it will send confirmation to client to really establish connection - so client knows about it succeed.
If you are sending packets before that happens - it will be lost.
Just do this:
[self performSelector:#selector(sendPacketToAllClients) withObject:nil afterDelay:1.0];
instead of:
[self sendPacketToAllClients];
I had the same problem that connection is established in different moment with small delay on client. The best is to send first packet from client that he is ready to receive packets from server - and than proceed normally from there.
Also try debugging:
- (void)session:(GKSession *)session peer:(NSString *)peerID didChangeState:(GKPeerConnectionState)state
On both devices (server and client).
I have also had my troubles with GKSession. I was interested to learn (on this site) today that GKSession is being deprecated in favor of using the Multipeer Connectivity Framework. With luck, Wenderlich et al. will do a tutorial using the new technology. :)
The system has some similarities to GKSession, so is not too hard to wrap your head around.

Closed 11 years ago.
My application times out while trying to connect to host. The timeout time is set to unlimited so I take it that the client is really just unable to connect at all.
I have an iPad app running asyncsockets and I'm trying to get it to connect to a server on my desktop also using asyncsockets. The iPad is specifically iOS 5 and is using GCD asyncsockets.
The server is being invoked through a NSRunLoop. It receives no form of connection from the client (none of breakpoints are caught like they are for telnet connections).
I'm able to telnet into the server from other machines just fine. I'm also able to connect the iPad client to host:google.com on port:80 just fine.
I've tried connecting the iPad to the server on ports 8080, 4500, and 50000 all to no success (they all work for telnet though).
I believe there is something in the server code causing this but I am not sure.
My server code is from a sample found here: http://mysterycoconut.com/blog/2010/07/tweak-away/
My client code is modified HTTP client code from the sample GCD code supplied by the asyncsockets repository: https://github.com/robbiehanson/CocoaAsyncSocket/blob/master/Examples/GCD/SimpleHTTPClient/Mobile/SimpleHTTPClient/SimpleHTTPClientAppDelegate.m

I've looked around for answers but have had no success. I figured the best course of action would be to ask you all rather than wrack my brain trying to solve it myself.
The solution was to connect to the local network differently. I was operating with a network that required a log in for local access but offered a "visitors" connection for wide area network access. The device (iPad) was automatically connecting as a "visitor" and I needed to log in manually.
So, if you aren't able to connect w/ this API, check out how your connecting to the network!
