【问题描述】：

我很乐意将这种软件组合用于一些简单的推送通知。

发送和接收不是问题 - 做到了！

但是我如何才能告诉 ios 之外的 jQueryMobile 应用程序它是由 PushNotification 启动的，并且不应该显示主屏幕而是显示其他与通知相关的屏幕？

【参考方案1】：

Notification 对象具有属性applicationLaunchNotification，如果应用程序通过通知启动，则其值为1。

以下方法查询应用程序启动时的待处理通知：

window.plugins.pushNotification.getPendingNotifications(function(notifications) 
     if(notifications.length > 0)
          var note = notifications[0];
          if(note.applicationLaunchNotification == "1")
              // do the processing
          
     
);

【讨论】：

这不是重点。问题是，如何告诉应用程序的 html 部分，有一个新的通知并切换到不同的屏幕？

【参考方案2】：

使用可以更改您的应用程序代理代码并启用应用程序提供配置文件中的推送 #import "AppDelegate.h" #import "MainViewController.h"

    #import <Cordova/CDVPlugin.h>

    @implementation AppDelegate

    @synthesize window, viewController;

    - (id)init
    
        /** If you need to do any extra app-specific initialization, you can do it here
         *  -jm
         **/
        NSHTTPCookieStorage* cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];

        [cookieStorage setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];

        self = [super init];
        return self;
