How can I make my push notification alert for my app show in a top rectangle on the phone when it's not locked. Right now I only see it on the locked screen.
Thanks
You are looking for a way to display push notifications when you app is running and in the foreground? That is, you want notifications that are received while your app is running to look just like notifications that are received when your app is not running? Unfortunately, iOS has no support for this. When your app is in the foreground, it is notified via [UIApplicationDelegate application:didReceiveRemoteNotification:] when a notification is received, but nothing is displayed. You'll have to write your own UI code to display a banner at the top of the screen when this method is called.

There is several situations when receiving a remote notification:
app is not launched at all
app is foreground
app is background
what I am looking for is that user haven't click the notification to launch or active the app. can we catch the receiving and do some thing in such three situation?
I know 2 is ok, how about 1 and 3, and how to do it? thx a lot.
somebody mentions widget or NotificationService? is it possible?
You can try adding a Notification Service Extension to your app.
iOS will launch your extension (NOT your app) in background when it receives a push notification. Obviously what you can do inside an extension is fairly limited.
There are two ways to be notified when your app moves to the background: implement the applicationWillResignActive() method in your app delegate, or register for the UIApplication.willResignActiveNotification notification anywhere in your app. This particular notification is sent as soon as your app loses focus, meaning that it's triggered when the user taps the home button once (to return to the home screen) or double taps the home button (to enter multi-tasking).
If the iOS app is open and a push message arrives, the push message does not appear in the NotificationCenter. I can process the content in the opened app. But the typical banner doesn't come.
Does anyone have a solution for Appcelerator (iOS)?
Or do I know whether the app was opened via a push message?
Thank you
You have to create an alert or something else yourself while the app is running in foreground. The notification will only appear when it is in background.
My app is receiving a notification and my problem is that when I received one or more notifications in the background and when i click the app icon to bring me in my app foreground then the notification message(s) doesn't able to display in the foreground it will only works if I click the pop up message in notification center not the icon.
You will not get remote push notification data on launch of app after tapping icon. You can only parse push notification body only on tap of notification alert.
So if you want to do any MUST NEED operation for such notifications there is only way is to introduce server in between. So you can use any web service for it and this will be called every time your app launches or comes to foreground. Call that API on background and do the needful you want.
I'm having a little problem in my app : I use to send local notifications to the user when actions are performed in my app, while it's running in background. Notifications are displayed perfectly in the notification center, but there is no pop-up when the notification occurs.
If I'm right, apps running in foreground can't display pop-up on the user screen (only in the notification center) but when the app is running in background, in fact there is pop-up displayed automatically ?
Thanks for your help !
EDIT : In fact, I'm speaking about a notification banner to be displayed too when the notification appear in the notification center.
When your app will go in background then you will see an immediate notification on your phone but you have to tap that notification to trigger didReceiveLocalNotification delegate.
If you receive local notification in foreground then didReceiveLocalNotification will be triggered automatically.
Above scenario is tested and verified.
Update: You must read this documentation: http://www.thekspace.com/home/component/content/article/62-uilocalnotification-demystified.html
I am detecting for iBeacon in background. When my device comes in a particular region application should comes to foreground.
It cannot be done without user interaction. The only option is you can generate a push notification to tell the user to bring the application to foreground.
This is from the Apple documentation about this issue:
When the operating system delivers push notification (iOS or OS X)
and the target application is not running in the foreground, it
presents the notification (alert, icon badge number, sound). If there
is a notification alert and the user taps or clicks the action button
(or moves the action slider), the application launches and calls a
method to pass in the local-notification object or remote-notification
payload. If the application is running in the foreground when the
notification is delivered, the application delegate receives a local
or push notification.
To answer to some comments about WhatsApp, with it, when you receive a classic vocal call, IOS use CallKit to display your call and wake up your phone, but it's not inside app. I try to make a video call with WhatsApp, and in this case, there is a notification. Press notification open app and answer to the call.
Conclusion : It's impossible to wake up app from background to foreground in IOS, but it's not really a problem because you can use notification to display what you want and get the user to your app after a touch on your notification. All of iPhone users are familiar with this kind of interaction, it's better to deal with it.
