设备： iPhone xs stop后报错；[图片] 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(); },
