用户在后台收到推送后手动打开应用程序时获取推送通知有效负载 [英] Getting push notification payload when user opens app manually after push has been received in the background

问题描述

我正在使用iOS7，并且试图确定在以下情况下是否可以获取JSON有效负载.

I am using iOS7 and I am trying to determine if I can get the JSON payload in the following situation.

• 我启用了后台模式远程通知"
• 应用终止时收到推送通知
• 该应用是通过通知中心中的图标非手动启动的

• I have background mode "remote-notifications" enabled
• The push notification is received while the app is terminated
• The app is launched manually from the icon not from the notification center

在收到通知后，我从图标本身启动应用程序时，我没有收到来自启动选项的推送

When I launch the app from the icon itself after the notification has been received I do not get the push in the launch options from

<代码>-(BOOL)应用程序:(UIApplication *)应用程序didFinishLaunchingWithOptions:(NSDictionary *)launchOptions;

并且当通过图标手动启动应用程序时，以下方法也不会被调用

and the following method does not get called either when app is manually launched from the icon

<代码>-(void)应用程序:(UIApplication *)应用程序didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void(^)(UIBackgroundFetchResult))completionHandler {

推荐答案

我终于弄清楚了如何获得它！

I finally figured out how you can get this!

从iOS 7开始，您可以获取它！

As of iOS 7 you can get it!

基本上，您需要为后台远程通知配置应用程序.

Basically, you need to configure your application for background remote notifications.

因此，在您的info.plist文件中:所需背景-将其设置为 app从推送通知中下载内容.

So, in your info.plist file: For required backgrounds - set it to app downloads content from push notifications.

在 AppDelegate.m 文件中，您需要实现此方法:

In the AppDelegate.m file, you need to implement this method:

-(void)应用程序:(UIApplication *)应用程序didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void(^)(UIBackgroundFetchResult))completionHandler

有关如何实现该功能的信息，请参见以下内容: didReceiveRemoteNotification:fetchCompletionHandler:打开从图标vs推送通知中

See this for how to implement that: didReceiveRemoteNotification: fetchCompletionHandler: open from icon vs push notification

对于推送通知，您必须具有'content-available':1，作为推送通知的一部分.这就是在显示警报之前告诉应用程序有新内容的原因.

For your push notifications, you must have 'content-available': 1, as part of the push notification. This is what tells the application that there is new content before displaying the alert.
