## How do I connect to my WebSocket server?
|
|
|
|
This library is **NOT** a WebSockets library. This library is only for servers that implement the socket.io protocol,
|
|
such as [socket.io](https://socket.io/). If you need a plain WebSockets client check out
|
|
[Starscream](https://github.com/daltoniam/Starscream) for Swift and [JetFire](https://github.com/acmacalister/jetfire)
|
|
for Objective-C.
|
|
|
|
## Why isn't my event handler being called?
|
|
|
|
One of the most common reasons your event might not be called is if the client is released by
|
|
[ARC](https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/AutomaticReferenceCounting.html).
|
|
|
|
Take this code for example:
|
|
|
|
```swift
|
|
class Manager {
|
|
func addHandlers() {
|
|
let manager = SocketManager(socketURL: URL(string: "http://somesocketioserver.com")!)
|
|
|
|
manager.defaultSocket.on("myEvent") {data, ack in
|
|
print(data)
|
|
}
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
This code is **incorrect**, and the event handler will never be called. Because as soon as this method is called `manager`
|
|
will be released, along with the socket, and its memory reclaimed.
|
|
|
|
A correct way would be:
|
|
|
|
```swift
|
|
class Manager {
|
|
let manager = SocketManager(socketURL: URL(string: "http://somesocketioserver.com")!)
|
|
|
|
func addHandlers() {
|
|
manager.defaultSocket.on("myEvent") {data, ack in
|
|
print(data)
|
|
}
|
|
}
|
|
}
|
|
|
|
```
