@td-design/rn-hooks/lib/commonjs/useInterval/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 useInterval(fn, delay, options) {
    var _a;
    var immediate = (_a = options === null || options === void 0 ? void 0 : options.immediate) !== null && _a !== void 0 ? _a : false;
    var timerCallback = index(fn);
    var timer = react.useRef();
    react.useEffect(function () {
        if (!lodashEs.isNumber(delay) || delay < 0)
            return;
        if (immediate) {
            timerCallback();
        }
        timer.current = setInterval(timerCallback, delay);
        return clear;
    }, [delay, immediate]);
    var clear = index(function () {
        if (timer.current) {
            clearInterval(timer.current);
        }
    });
    return clear;
}

module.exports = useInterval;
