reactNative 获取组件高、宽、位置等信息

import {findNodeHandle, UIManager} from 'react-native'

layout(ref) {
    const handle = findNodeHandle(ref);

    return new Promise((resolve) => {
      UIManager.measure(handle, (x, y, width, height, pageX, pageY) => {
        resolve({
          x,
          y,
          width,
          height,
          pageX,
          pageY
        });
      });
    });
  }
