如何在Swift中通過tcp socket讀取字符串

Question

如果我有一個java tcp服務器發送一些文本，我如何從NSInputStream讀取該文本並將其存儲在字符串中？

這是我有一大堆代碼，但我不確定如何從這里獲取字符串：

NSStream.getStreamsToHostWithName(addr, port: port, inputStream: &inp, outputStream: &out)

let inputStream = inp!
let outputStream = out!
inputStream.open()
outputStream.open()

var readByte :UInt8 = 0
while inputStream.hasBytesAvailable {
    inputStream.read(&readByte, maxLength: 1)
}

使用您的代碼，每次循環內部只能讀取1個字節。 如果你需要讀取所有數據，你可以這樣做：

NSStream.getStreamsToHostWithName(addr, port: port, inputStream: &inputStream, outputStream: &outputStream)
inputStream!.open()
outputStream!.open()

let queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)
dispatch_async(queue) {
    let bufferSize = 1024
    var inputBuffer = Array<UInt8>(count:bufferSize, repeatedValue: 0)
    while true {
        let bytesRead = self.inputStream!.read(&inputBuffer, maxLength: bufferSize)

        // Here get string from byte Array
        let responseString = NSString(bytes: inputBuffer, length: inputBuffer.count, encoding: NSUTF8StringEncoding) as! String
        println("Data from Stream = \(responseString)")
    }
}

這是這行：

let responseString = NSString(bytes: inputBuffer, length: inputBuffer.count, encoding: NSUTF8StringEncoding) as! String

從輸入字節數組創建String
