如何仅在应用程序中使用iOS推送通知

Question

I am working on a app, where I need to send a push notification to the app to start processing data as needed.

How do I send a push notification to the device so that instead of showing the alert message , the notification is forwarded to the app - whether the app is in the foreground or background..

I did implement the delegate method :

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler

however this is called only when the app is in the foreground . When the app is in the background the notification shows up on the notification center .

Please advice.

Answer 1

To make this works you need to do few step:

• set background mode remote-notification

• implement application:didReceiveRemoteNotification:fetchCompletionHandler: method in app delegate

• and make sure push notification payload contains key "content-available" : 1

Answer 2

Is your application using a backend? An example would be Parse or another to store your data.

Parse, for example, allows you to add push notifications that can be customized and changed to get the most out of your application.
