macos - Swift:无法在 NSSpeechRecognizer 中设置命令

Question

我对 setCommands 有疑问。我无法在我的项目中为 setCommands 设置命令。在 viewDidLoad 中，我尝试了 SR.setCommands = commands 但我收到一条错误消息“‘NSSpeechRecognizer’ 没有名为‘setCommands’的成员”有什么帮助吗？

class ViewController: NSViewController, NSSpeechRecognizerDelegate {

@IBOutlet weak var Label: NSTextField!

var SR:NSSpeechRecognizer = NSSpeechRecognizer()
var commands: [AnyObject]? = ["word","sad","happy"]

override func viewDidLoad() {
    super.viewDidLoad()

    SR.setCommands = commands //Error
}

override var representedObject: AnyObject? {
    didSet {
    // Update the view, if already loaded.
    }
}

@IBAction func Listen(sender: AnyObject) {
    SR.startListening(); print("listening")
}

func speechRecognizer(sender: NSSpeechRecognizer,
    didRecognizeCommand command: AnyObject?){

        if (command as String == "word")
        {
            println("Hello")
        }
        else
        {
            println("NotWord")
        }

    }

@IBAction func Stop(sender: AnyObject) {
    SR.stopListening()
}

使用:

SR.commands = commands

您将点符号与旧的 Obj-C 风格的 setter 混合在一起。

你也可以使用 let 作为你的语音识别器，你不需要声明任何一个的类型； Swift 会推断它:

let SR = NSSpeechRecognizer()
var commands = ["word","sad","happy"]
