@td-design/rn-hooks/lib/commonjs/useTimeout/index.js

从ahooks里面抽取的一些在rn项目里可以使用的hooks。提高开发效率

'use strict';

var react = require('react');
var lodashEs = require('lodash-es');
var index = require('../useMemoizedFn/index.js');

function useTimeout(fn, delay) {
    var timerCallback = index(fn);
    var timer = react.useRef();
    react.useEffect(function () {
        if (!lodashEs.isNumber(delay) || delay < 0)
            return;
        timer.current = setTimeout(function () {
            timerCallback();
        }, delay);
        return clear;
        // eslint-disable-next-line react-hooks/exhaustive-deps
    }, [delay]);
    var clear = index(function () {
        if (timer.current) {
            clearInterval(timer.current);
        }
    });
    return clear;
}

module.exports = useTimeout;
