我希望能够在我的Swift iOS应用程序中有效地使用UITextView作为按钮。当我点击文本视图时,我不希望它是可编辑的,但我希望它能够更改文本视图的背景颜色并开始在应用程序中使用语音识别软件。我已经看到了其他类似的问题,但没有人回答这个具体问题。
func textViewShouldBeginEditing(_ textView: UITextView) -> Bool {
guard textView == inView else {
guard textView == resultView else {
return false
}
nextButton.isEnabled = true
return false
}
if audioEngine.isRunning {
let myColor: UIColor = UIColor(red: 50, green: 0, blue: 0, alpha: 0.75)
inView.layer.backgroundColor = myColor.cgColor
audioEngine.inputNode.removeTap(onBus: 0)
globalVariables.boolRecording = false
audioEngine.stop()
recognitionRequest?.endAudio()
microphoneButton.isEnabled = true
microphoneButton.setTitle("Start Recording", for: .normal)
globalVariables.finalText = globalVariables.finalText + globalVariables.tempText
globalVariables.tempText = ""
self.inView.text = ""
return false
} else {
let myColor: UIColor = UIColor(red: 0, green: 50, blue: 0, alpha: 0.75)
inView.layer.backgroundColor = myColor.cgColor
globalVariables.boolRecording = true
startRecording()
microphoneButton.setTitle("Stop Recording", for: .normal)
return false
}
}

您可以使用UITextViewDelegate方法:textViewShouldBeginEditing。
从此方法返回false
以防止将此特定文本字段设为firstResponder并更改背景并开始语音识别。
func textViewShouldBeginEditing(_ textView: UITextView) -> Bool {
guard textView == speechTextView else {
return true
}
// Change bg
speechTextView.backgroundColor = UIColor.blue
// Start speech
startSpeechRecognition()
return false
}
不要忘记将UITextview的委托添加到自己:
speechTextView.delegate = self
