#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)(timeout: 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 emit:@"echo" withItems:@[@"echo test"]];
    [socket emitWithAck:@"ackack" withItems:@[@1]](10, ^(NSArray* data) {
        NSLog(@"Got ack");
    });
}];

[socket connect];

##Features

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

##Installation Requires Swift 1.2/Xcode 6.3

If you need Swift 1.1/Xcode 6.2 use v1.5.2. (Pre-Swift 1.2 support is no longer maintained) Manually (iOS 7+)

1. Copy the SocketIOClientSwift folder into your Xcode project. (Make sure you add the files to your target(s))
2. If you plan on using this from Objective-C, read this on exposing Swift code to Objective-C.

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.
• log: Bool If true socket will log debug messages. Default is false.
• sessionDelegate: NSURLSessionDelegate Sets an NSURLSessionDelegate for the underlying engine. Useful if you need to handle self-signed certs. Default is nil.
• path: String - If the server uses a custom path. ex: "/swift". Default is ""

Methods

1. 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. onAny(callback:((event:String, items:AnyObject?)) -> Void) - Adds a handler for all events. It will be called on any received event.
3. emit(event:String, _ items:AnyObject...) - Sends a message. Can send multiple items.
4. emit(event:String, withItems items:[AnyObject]) - emit for Objective-C
5. emitWithAck(event:String, _ items:AnyObject...) -> (timeout:UInt64, callback:(NSArray?) -> Void) -> Void - Sends a message that requests an acknowledgement from the server. Returns a function which you can use to add a handler. See example. Note: The message is not sent until you call the returned function.
6. emitWithAck(event:String, withItems items:[AnyObject]) -> (UInt64, (NSArray?) -> Void) -> Void - emitWithAck for Objective-C. Note: The message is not sent until you call the returned function.
7. connect() - Establishes a connection to the server. A "connect" event is fired upon successful connection.
8. connectWithParams(params:[String: AnyObject]) - Establishes a connection to the server passing the specified params. A "connect" event is fired upon successful connection.
9. 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.
10. reconnect() - Causes the client to reconnect to the server.

Client Events

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