请问 iOS callBack 回调 想用fireGlobalEvent方法 在哪设置

[liwenyou]

既然是callback，为什么还用fireGlobalEvent？

fireGlobalEvent可以这么设置：

Utils.js

var globalEvent weex_define('@weex-temp/api', function (weex_require) { globalEvent = __weex_require__('@weex-module/globalEvent') });

exports.addEventListener = function (eventName, callback) { globalEvent.addEventListener(eventName, callback); }

---

xxx.we

Utils.addEventListener("eventName", function (param) { //do something });

---

xxx.m //原生代码

[_instance fireGlobalEvent:@"eventName" params:@{@"key":@"value"}];

@liwenyou 自己写了一个 baseViewController 想利用fireGlobalEvent进行回调 该如何更改呢
