Question

我已经设置了一个处理推送通知的模块，其中包含：

//myPush module
var CloudPush = require('ti.cloudpush'); 
...
        var setAppPushNotifications = function(cback) {
            // Process incoming push notifications
            log('cback=' + typeof cback);  //log is a wrapper to Ti.API.info
            CloudPush.addEventListener('callback', function (evt,cback) {
                log('Inside CloudPush-Callback.');
                log('cback=' + typeof cback); 
                getIncomingNotification(evt, cback);
            });
        };
        var getIncomingNotification = function(evt,cback) {
            //return if zero payload 
            //test for app required basic fields
            log('cback=' + typeof cback); 
            cback(evt.payload);
        };

场景：我在Controller中使用它，以便我可以传递与Controller相关的回调（例如，在回调处理之后我想关闭控制器/视图并打开另一个）：

//controller code
var myPush = Alloy.Globals.myPush; 
...
    myPush.setAppPushNotifications(processNotificationPayload);

    function processNotificationPayload(p) {
        //select notification channel
        //do some processing...
        //close controller and view and get back to index.
    }

问题是： cback 功能未被传递，或者，在 CloudPush-callback 事件被调用时， cback 不再存在了。我得到了以下日志：

[myPush.js][setAppPushNotifications]: cback=function
[myPush.js][setAppPushNotifications]: cback=undefined
[myPush.js][getIncomingNotification]: cback=undefined

关于给定方案的解决方案是什么？请告诉我一些代码。感谢。

尝试这个......

//myPush module
var CloudPush = require('ti.cloudpush'); 
...
        var setAppPushNotifications = function(cback) {
            // Process incoming push notifications
            log('cback=' + typeof cback);  //log is a wrapper to Ti.API.info
            CloudPush.addEventListener('callback', function (evt) {
                log('Inside CloudPush-Callback.');
                log('cback=' + typeof cback); 
                getIncomingNotification(evt,cback);
            });
        };
        var getIncomingNotification = function(evt,cback) {
            //return if zero payload 
            //test for app required basic fields
            log('cback=' + typeof cback); 
            cback(evt.payload);
        };
