快速组合代码

Question

我正在使用 Xcode/Swift 编写一个应用程序。我想将这两个代码功能组合成一个更小的代码功能，以消除重复代码。

第一段代码:

@IBAction func StopRecording(_ sender: Any) {
     recordButton.isEnabled = true
     stopRecordingButton.isEnabled = false
     recordingLabel.text = "Tap to record"
     audioRecorder.stop()
     let audioSession = AVAudioSession.sharedInstance()
     try! audioSession.setActive(false)
}

第二段代码:

@IBAction func recordAudio(_ sender: AnyObject) {
    recordingLabel.text = "Recording in progress"
    stopRecordingButton.isEnabled = true
    recordButton.isEnabled = false

这是我的错误尝试:

@IBAction func recordAudio(_ sender: AnyObject) {
        func SetLabel(recordButton: Bool, recordingText:String)
        if recordButton = true
            recordingLabel.text = "Recording in progress"
            stopRecordingButton.isEnabled = true
            recordButton.isEnabled = false
    else if {
        @IBAction func StopRecording(_ sender: Any) {
            recordButton.isEnabled = true
            stopRecordingButton.isEnabled = false
            recordingLabel.text = "Tap to record"
            audioRecorder.stop()
            let audioSession = AVAudioSession.sharedInstance()
            try! audioSession.setActive(false)
        }
                }

    {

Answer 1

试试这个:

func updateButtons(recording: Bool) {
    recordingLabel.text = recording ? "Recording in progress" : "Tap to record"
    stopRecordingButton.isEnabled = recording
    recordButton.isEnabled = !recording
}
