Question

我尝试了以下代码

count + = 2

    if count > 100 {
        soundRecorder?.stop()

        if player != nil {
            if player!.isPlaying {
                player!.stop()
            }
        }

        print("Recording complete")

    }

    soundRecorder?.updateMeters()

    if !(soundRecorder?.isRecording)! {
        visualizerTimer?.invalidate()
        visualizerTimer = nil
    }
    else {
        self.progressView.setProgress(visualizerTimer, animated: true) // receiving error for "Cannot convert value of type 'Timer?' to expected argument type 'Float'"
        print("Recording")
    }

我希望progressView应该根据录制的音频大小移动，如果音频播放1分钟，则progressView应该根据音频时间移动。请帮助我解决这个问题。***

尝试实现此代码，对您有帮助

 let intervel = CMTime(value: 1, timescale: 2)
            player?.addPeriodicTimeObserver(forInterval: intervel, queue: DispatchQueue.main, using: { (progressTime) in

                let seconds = Int(CMTimeGetSeconds(progressTime))

                let secondsString = String(format: "%02d", seconds % 60)
                 let minutesAString = String(format: "%02d", seconds / 60)

                // move the slider

                if let duration = self.player?.currentItem?.duration {
                    let durationSeconds = Int(CMTimeGetSeconds(duration))
                    print("value of duratioinSeconds: \(seconds))")
                    print("value of Seconds: \(durationSeconds)")

                     print(Float(seconds % durationSeconds))
                    self.Slider.setValue(Float(durationSeconds), animated: true)
                    self.Slider.minimumValue = 1
                    self.Slider.maximumValue = Float(durationSeconds)
                    self.Slider.value = Float(seconds % durationSeconds)
                }

            })

如果您使用的是AVPlayer，则此代码应该对您有用，我在其中一个应用程序中使用了它。它确实需要您设置当前播放项目的持续时间。您可以使用Complete output from command python setup.py egg_info: TypeError: 'tuple' object is not callable The above exception was the direct cause of the following exception: Traceback (most recent call last): File "<string>", line 1, in <module> File "C:\Users\TOSHIB~1\AppData\Local\Temp\pip-req-build-hztbm9lf\setup.py", line 13, in <module> include_dirs=[numpy.get_include()])] File "c:\python34\lib\site-packages\setuptools\__init__.py", line 129, in setup return distutils.core.setup(**attrs) File "c:\python34\lib\distutils\core.py", line 148, in setup dist.run_commands() File "c:\python34\lib\distutils\dist.py", line 955, in run_commands self.run_command(cmd) File "c:\python34\lib\distutils\dist.py", line 971, in run_command log.info("running %s", command) File "c:\python34\lib\distutils\log.py", line 44, in info self._log(INFO, msg, args) File "c:\python34\lib\distutils\log.py", line 33, in _log msg = msg.encode(encoding, "backslashreplace").decode(encoding) TypeError: encoding with 'cp1252' codec failed (TypeError: 'tuple' object is not callable)属性来调整此方法的运行频率（这将更改progressView的更改程度）
