Platforms ios 7.0, requires ARC

SIOSocket is simple interface for communicating with Socket.IO 1.0 from iOS.

There is now a first-party iOS client for Socket.IO! (Therefore, this library is no longer being actively developed.) Congrats to the Socket.IO team for a job well done.

No Maintenance Intended

How to use

SIOSocket can be added as a CocodaPod, submodule, or standalone dependency to any iOS 7.0 (or greater) project.

pod 'SIOSocket', '~> 0.2.0'


#import <SIOSocket/SIOSocket.h>

// ...
[SIOSocket socketWithHost: @"http://localhost:3000" response: ^(SIOSocket *socket) {
    self.socket = socket;

or, in Swift…

// ...
SIOSocket.socketWithHost("http://localhost:3000") { (socket: SIOSocket) in
    self.socket = socket

typedef NSArray SIOParameterArray

An NSArray of these JSValue-valid objects:

  • NSNull
  • NSString
  • NSNumber
  • NSDictionary
  • NSArray
  • NSData


+ (void)socketWithHost:response:

Generates a new SIOSocket object, begins its connection to the given host, and returns it as the sole parameter of the response block.

The host reachable at the given URL string should be running a valid instance of a server.

+ (void)socketWithHost:reconnectAutomatically:attemptLimit:withDelay:maximumDelay:timeout:withTransports:response:

  • reconnectAutomatically whether to reconnect automatically (YES)
  • attemptLimit number of times to attempt a reconnect (Infinite)
  • reconnectionDelay how long to wait before attempting a new
    reconnection (1)
  • maximumDelay maximum amount of time to wait between
    reconnections (5). Each attempt increases the reconnection by
    the amount specified by reconnectionDelay.
  • timeout connection timeout before an onReconnectionError event is emitted (20)
  • withTransports specifies an array of transports for (default is ‘polling’, ‘websocket’).


void (^onConnect)()

Called upon connecting.

void (^onDisconnect)()

Called upon a disconnection.

void (^onError)(NSDictionary *errorInfo)

Called upon a connection error.

void (^onReconnect)(NSInteger numberOfAttempts)

Called upon a successful reconnection.

void (^onReconnectionAttempt)(NSInteger numberOfAttempts)

Called upon an attempt to reconnect.

void (^onReconnectionError)(NSDictionary *errorInfo)

Called upon a reconnection attempt error.



Binds the given void (^)(SIOParameterArray *) block, function, to the given event.

function is called upon a firing of event.



Fires the given event with then given SIOParameterArray as arguments.
