watchOS 3是否支持SpeechKit框架？

Question

我尝试为watchOS导入SpeechKit框架，但收到一个错误。有没有办法把它和手表一起使用？当我导入Speechkit框架时，我收到一个错误，说“没有这样的模块语音”。

import WatchKit
import Foundation
import Speech

class SpeechInterfaceController: WKInterfaceController, SFSpeechRecognizerDelegate {

override func awake(withContext context: Any?) {
    super.awake(withContext: context)

    // Configure interface objects here.
}

override func willActivate() {
    // This method is called when watch view controller is about to be visible to user
    super.willActivate()
}

override func didDeactivate() {
    // This method is called when watch view controller is no longer visible
    super.didDeactivate()
}

}

Answer 1

Speech框架不在watchOS开发工具包中(至少在watchOS 3.0-3.1版本中)。您可以看到这个in the framework docs

​

​

(如果它支持watchOS、tvOS或macOS，这些将列在该页面的SDK下。)

您还可以在Xcode SDK中查看可用的框架集:查看Xcode.app/Contents/Developer/Platforms/WatchOS.platform/Developer/SDKs/WatchOS3.1.sdk/System/Library/Frameworks/，或者在查看watchOS系统头文件的ObjC版本时查看Xcode编辑器窗格顶部的跳转栏，或者在手动添加到项目的WatchKit扩展目标的链接框架和库时查看可用选项列表。

watchOS 3不支持SpeechKit框架。

要在手表应用程序中获得语音识别功能，您可以使用：

presentTextInputController(withSuggestions: nil, allowedInputMode: .plain) { (results) in
    if let results = results?.first as? String {
        self.label.setText(results)
    }
}
