按钮开/关设置中的声音

Question

我有两个ViewController（ViewController和Settings）。如果关闭Switch，按钮（或应用程序中）的声音被关闭并打开，我怎么能这样做？

按钮声音代码：

@IBAction func SoundButton(_ sender: UIButton) {
    let filename = "button-16"
    let ext = "mp3"

    if let soundUrl = Bundle.main.url(forResource: filename, withExtension: ext) {
        var soundId: SystemSoundID = 0

        AudioServicesCreateSystemSoundID(soundUrl as CFURL, &soundId)

        AudioServicesAddSystemSoundCompletion(soundId, nil, nil, { (soundId, clientData) -> Void in
            AudioServicesDisposeSystemSoundID(soundId)
        }, nil)

        AudioServicesPlaySystemSound(soundId)
    }
}

Answer 1

为boolean获取全局isSound变量UISwitch。当UISwitch on表示true时，请设置变量isSound on。现在，根据变量制作条件。

您可以使用AppDelegate文件或头文件创建全局变量。 （.h file）

if isSound == true || isSound == on {
// make sound on
} else {
// make sound off
}

在我的代码中，我正在播放文本语音和管理

    var speedd = AVSpeechSynthesizer()
        var voicert = AVSpeechUtterance()
var Strdata = "This is Sound for Music"
        override func viewDidLoad()
            {
                super.viewDidLoad()

        voicert = AVSpeechUtterance(string:Strdata)
        voicert.voice = AVSpeechSynthesisVoice(language: "en-US")
         voicert.rate = 0.5
        }
        @IBAction func switchSound(_ sender: UISwitch)
            {

                if sender.isOn
                {
                    speedd.speak(voicert)
                }
                else
                {
                   speedd.stopSpeaking(at: AVSpeechBoundary.immediate)
                }

            }
