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 listeners = {};
var trigger = function (key, data) {
    if (listeners[key]) {
        listeners[key].forEach(function (item) { return item(data); });
    }
};
var subscribe = function (key, listener) {
    if (!listeners[key]) {
        listeners[key] = [];
    }
    listeners[key].push(listener);
    return function unsubscribe() {
        var index = listeners[key].indexOf(listener);
        listeners[key].splice(index, 1);
    };
};

exports.subscribe = subscribe;
exports.trigger = trigger;
