I want to open a TCP connection with an OBD dongle based on ELM327 chip. So I have decided to use GCDAsyncSocket library. I wrote this code,
import UIKit
import CocoaAsyncSocket
class ViewController: UIViewController, GCDAsyncSocketDelegate {
let addr = "192.168.0.10"
let port:UInt16 = 35000
var socket:GCDAsyncSocket!
override func viewDidLoad() {
super.viewDidLoad()
socket = GCDAsyncSocket(delegate: self, delegateQueue: dispatch_get_main_queue())
do {
try socket.connectToHost(addr, onPort: port)
} catch let e {
print(e)
}
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func connect(sender: AnyObject) {
print("Clicked")
}
func socket(socket : GCDAsyncSocket, didConnectToHost host:String, port p:UInt16)
{
print("Connected to \(addr) on port \(port).")
}
}
but when I run the code , the function:
func socket(socket : GCDAsyncSocket, didConnectToHost host:String, port p:UInt16)
never gets run.
Where is the problem?
Can anybody advice me about how to transmit and recive literal byte string.
Thanks
I also had a problem, and I solve it like below.
You have to make class inherit from NSObject.
import Foundation
import CocoaAsyncSocket
public class MySocket: NSObject, AsyncSocketDelegate {
var mSocket: AsyncSocket!
override init() {
super.init()
let mSocket = AsyncSocket.init(delegate: self)
do {
print("Connecing to socket server...")
try mSocket.connectToHost("google.com", onPort: 80)
} catch let error {
print(error)
}
}
@objc public func onSocket(sock: AsyncSocket!, didConnectToHost host: String!, port: UInt16) {
print("success")
}
}
Below link can help you.
