@td-design/rn-hooks/lib/module/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

import { useRef, useEffect } from 'react';
import { isNumber } from 'lodash-es';
import useMemoizedFn from '../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 = useMemoizedFn(fn);
    var timer = useRef();
    useEffect(function () {
        if (!isNumber(delay) || delay < 0)
            return;
        if (immediate) {
            timerCallback();
        }
        timer.current = setInterval(timerCallback, delay);
        return clear;
    }, [delay, immediate]);
    var clear = useMemoizedFn(function () {
        if (timer.current) {
            clearInterval(timer.current);
        }
    });
    return clear;
}

export { useInterval as default };
