swift - SWIFT - 如何为服务器获取流

Question

在客户端，我们可以使用 CFStreamCreatePairWithSocketToHost 来获取 ReadStream 和 WriteStream。

服务器得到clientSocket后，我们如何得到ReadStream和WriteStream？

Answer 1

import UIKit

class Connection: NSObject, NSStreamDelegate {
    var inputStream: NSInputStream!
    var outputStream: NSOutputStream!

    func connect() {
        var readStream:  Unmanaged<CFReadStream>?
        var writeStream: Unmanaged<CFWriteStream>?

        CFStreamCreatePairWithSocketToHost(nil, "193.10.1.22", 17, &readStream, &writeStream)

        self.inputStream = readStream!.takeRetainedValue()
        self.outputStream = writeStream!.takeRetainedValue()

        self.inputStream.delegate = self
        self.outputStream.delegate = self

        self.inputStream.scheduleInRunLoop(NSRunLoop.currentRunLoop(), forMode: NSDefaultRunLoopMode)
        self.outputStream.scheduleInRunLoop(NSRunLoop.currentRunLoop(), forMode: NSDefaultRunLoopMode)

        self.inputStream.open()
        self.outputStream.open()
    }
}
