#Socket.IO-Client-Swift Socket.IO-client for iOS/OS X.

##Example

let socket = SocketIOClient(socketURL: "localhost:8080")

socket.on("connect") {data, ack in
    println("socket connected")
}

socket.on("currentAmount") {data, ack in
    if let cur = data?[0] as? Double {
        socket.emitWithAck("canUpdate", cur).onAck(0) {data in
            socket.emit("update", ["amount": cur + 2.50])
        }

        ack?("Got your currentAmount", "dude")
    }
}

// Connect
socket.connect()

##Objective-C Example

SocketIOClient* socket = [[SocketIOClient alloc] initWithSocketURL:@"localhost:8080" options:nil];

[socket on: @"connect" callback: ^(NSArray* data, void (^ack)(NSArray*)) {
    NSLog(@"connected");
    [socket emitObjc:@"echo" withItems:@[@"echo test"]];
    [[socket emitWithAckObjc:@"ackack" withItems:@[@"test"]] onAck:0 withCallback:^(NSArray* data) {
        NSLog(@"Got data");
    }];
}];

##Features

• Supports socket.io 1.0+
• Supports binary
• Supports Polling and WebSockets
• Supports TLS/SSL
• Can be used from Objective-C

##Installation Manually (iOS 7+)

1. Copy the SwiftIO folder into your Xcode project!

CocoaPods 0.36.0 or later (iOS 8+)

Create Podfile and add pod 'Socket.IO-Client-Swift':

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

pod 'Socket.IO-Client-Swift', '~> 1.3.2' # Or latest version

Install pods:

$ pod install

Import in your swift file:

import Socket_IO_Client_Swift

##API Constructors

init(socketURL: String, opts:NSDictionary? = nil) - Constructs a new client for the given URL. opts can be omitted (will use default values)

convenience init(socketURL: String, options:NSDictionary?) - Same as above, but meant for Objective-C. See Objective-C Example.

Options

• reconnects: Bool Default is true
• reconnectAttempts: Int Default is -1 (infinite tries)
• reconnectWait: Int Default is 10
• forcePolling: Bool Default is false. true forces the client to use xhr-polling.
• forceWebsockets: Bool Default is false. true forces the client to use WebSockets.
• nsp: String Default is "/"
• cookies: [NSHTTPCookie]? An array of NSHTTPCookies. Passed during the handshake. Default is nil.

Methods

1. socket.on(name:String, callback:((data:NSArray?, ack:AckEmitter?) -> Void)) - Adds a handler for an event. Items are passed by an array. ack can be used to send an ack when one is requested. See example.
2. socket.onAny(callback:((event:String, items:AnyObject?)) -> Void) - Adds a handler for all events. It will be called on any received event.
3. socket.emit(event:String, _ items:AnyObject...) - Sends a message. Can send multiple items.
4. socket.emitObjc(event:String, withItems items:[AnyObject]) - emit for Objective-C
5. socket.emitWithAck(event:String, _ items:AnyObject...) -> SocketAckHandler - Sends a message that requests an acknowledgement from the server. Returns a SocketAckHandler which you can use to add an onAck handler. See example.
6. socket.emitWithAckObjc(event:String, withItems items:[AnyObject]) -> SocketAckHandler - emitWithAck for Objective-C.
7. socket.connect() - Establishes a connection to the server. A "connect" event is fired upon successful connection.
8. socket.connectWithParams(params:[String: AnyObject]) - Establishes a connection to the server passing the specified params. A "connect" event is fired upon successful connection.
9. socket.close(#fast:Bool) - Closes the socket. Once a socket is closed it should not be reopened. Pass true to fast if you're closing from a background task.

Events

1. connect - Emitted when on a successful connection.
2. disconnect - Emitted when the connection is closed.
3. error - Emitted if the websocket encounters an error.
4. reconnect - Emitted when the connection is starting to reconnect.
5. reconnectAttempt - Emitted when attempting to reconnect.
