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()
}
最佳答案
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"]
