taro-hooks/es/useCamera/index.js

为 Taro 而设计的 Hooks Library

import { createCameraContext } from '@tarojs/taro';
import { useRef } from '@taro-hooks/core';
import usePromise from '../usePromise';
function useCamera() {
  var cameraContext = useRef(createCameraContext());
  var zoomAsync = usePromise(cameraContext.current.setZoom);
  var zoom = function zoom(zoomNumber) {
    return zoomAsync({
      zoom: zoomNumber
    });
  };
  var start = usePromise(cameraContext.current.startRecord);
  var stopAsync = usePromise(cameraContext.current.stopRecord);
  var stop = function stop(compressed) {
    return stopAsync({
      compressed: compressed
    });
  };
  var take = usePromise(cameraContext.current.takePhoto);
  var listener = function listener(callback) {
    return cameraContext.current.onCameraFrame(callback);
  };
  return [cameraContext.current, {
    zoom: zoom,
    start: start,
    stop: stop,
    take: take,
    listener: listener
  }];
}
export default useCamera;
