设备： iPhone xs

stop后报错；

代码如下：

record = wx.createMediaRecorder(cs,{
      duration:5,
      fps: 15
    });
    record.on('start', function(){
       console.log('start record', arguments)
  })

  record.on('stop', function({tempFilePath, duration, fileSize}){
    console.log('stop ');
      console.log(tempFilePath, fileSize)
      _this.setData({
        tempFilePath,
        fileSize
      })
  })
    record.start();


  <button bindtouchstart="stopRecord">停止录制</button>


  stopRecord(){
    record.stop();
  },
