简介
通过 WebSocket 可以实现保持长连接。
WebSocket第三方库
开始
编辑 Podfile
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
use_frameworks!
target 'Your target' do
pod 'Starscream'
end
执行 pod install。
创建 WebSocket 对象
mWebSocket = WebSocket(url: URL(string: "ws://localhost:8080/")!)
设置委托对象
mWebSocket.delegate = self
这里需要实现 WebSocketDelegate 协议
/// 连接成功后的回调
func websocketDidConnect(socket: WebSocketClient) {
print("websocketDidConnect")
}
/// 断开连接后的回调
func websocketDidDisconnect(socket: WebSocketClient, error: Error?) {
print("websocketDidDisconnect, error = \(String(describing: error))")
}
/// 接收到消息后的回调(String)
func websocketDidReceiveMessage(socket: WebSocketClient, text: String) {
print("websocketDidReceiveMessage, text = \(text)")
if text.contains("Hello Client") {
// 发送消息
mWebSocket.write(string: "Send msg from iOS Client by Cary")
}
}
/// 接收到消息后的回调(Data)
func websocketDidReceiveData(socket: WebSocketClient, data: Data) {
print("websocketDidReceiveData")
}
接下来进行 connect 操作
mWebSocket.connect()
断开连接操作
if mWebSocket.isConnected {
mWebSocket.disconnect()
}
WebSocket Server
Starscream 自带了个 Server 端的WebSocket示例，地址是 https://github.com/daltoniam/Starscream/tree/master/examples/SimpleTest。
按照对应的 README.md 操作即可。
