I am working on Blackberry Push Notification using MDS. I have referred the sample project HTTPPushDemo which Blackberry API has provided. I am getting pushed data successfully only when app is running. How I will get pushed notification using MDS when app is not running ?
The typical arrangement is to have two apps - the foreground app and the background app. The foreground app has all the UI elements, and it starts when the user clicks on the app icon on the device, and terminates when the user selects 'exit' This would largely be what you've written already.
The background app hides itself - no icon is present in the app switcher or on the device. This means the background app continues to run whether or not the foreground app is running. This allows you to setup the push listener, and keep it running even when your app is "not running"
Both 'apps' actually inhabit the same codebase - you differentiate them by adding a new start argument, and then in the app startup, the code checks whether it should be the foreground or background app, and behaves appropriately.

I need to notify the user about new features of my app as soon as the app update finishes and the app is not in the foreground (i.e., it is terminated or is in the background). How do I achieve this? This scenario will happen if the app was already installed and auto-updates were on.
I achieved this on Android using MY_PACKAGE_REPLACED broadcast receiver. I've read about NSNotificationName in NSNotificationCenter in iOS but couldn't find an equivalent to MY_PACKAGE_REPLACED.
You cannot do this with iOS without the app running in the background Period. Even if your app is running in the background after Appstore updates the app, your app gets killed and you don't have control over it until the user launches it for the first time.
Maybe you could try sending a silent push notification to the app to see if it responds and try to get the current app version.
application:didReceiveRemoteNotification: method, which is called only when your app is running in the foreground, the system calls this method when your app is running in the foreground or background. But I want to send push notification after force an app to close on iPhone, iPad, or iPod touch. It is important update my apps data silently. I have already tried silent push notification in background mode. But it's not work in quite mode.
Will iOS perform background tasks after the user has force-quit the app?
If perform, fiarebase push notification build in method application:didReceiveRemoteNotification: execute?
Please reply anyone...
No, apps that were force-closed via the task manager are not normally restarted when push notifications are received. This is documented here:
In most cases, the system does not relaunch apps after they are force quit by the user. One exception is location apps, which in iOS 8 and later are relaunched after being force quit by the user. In other cases, though, the user must launch the app explicitly or reboot the device before the app can be launched automatically into the background by the system. When password protection is enabled on the device, the system does not launch an app in the background before the user first unlocks the device
I'm trying to get data from url with background fetch. My func tries to get data and if there is a new data, it sends local notification. Background fetch works after about 10 - 20 minutes when i minimize the app. But when i kill the app (double click home button and close app) it doesn't work. I waited about 1 hour but it didn't work. I am using background service in android and it is working successfully. Is there any way to get data from url and send local notification when app is closed? I am using Xcode 6 and swift 1.2
The Background Fetching will NOT happen in your app after the user has killed it in the multitasking UI. This is by design.
Take a look at Apple's documentation that mentions:
Apps that support background execution may be relaunched by the system
to handle incoming events. If an app is terminated for any reason
other than the user force quitting it, the system launches the app...
and
In most cases, the system does not relaunch apps after they are force
quit by the user. One exception is location apps, which in iOS 8 and
later are relaunched after being force quit by the user. In other
cases, though, the user must launch the app explicitly or reboot the
device before the app can be launched automatically into the
background by the system.
As you noticed in the documentation, there's only 1 exception when the app will be relaunched if it was force killed: by using location services. Unfortunately this does not apply to you.
Also, you cannot detect if the app was force killed by the user. Check this StackOverflow answer.
The Background Fetching will NOT Update in your app after the user has killed app from background. it is not Possible
My app receives push notifications successfully if run at least once per boot both in the background and when force closed (thanks to PushKit).
If I reboot the device, I won't receive any pushes until I launch the app at least once.
How can I get this scenario working? I'm running latest Xcode and iOS (8.3)
If I leave the app running in the background when I reboot the device, the app still shows up in the recents menu however no pushes are received and no AppDelegate entry points are hit (that I have anyways).
All push/notification permissions are enabled as well as Background App Refresh
Background Mode Capabilities are enabled (VoIP, push, fetch)
The problem was that the app was going dormant before the callback to update credentials.
The solution was to start a background task in didLaunchWithOptions and end the background task in the didUpdatePushCredentials function.
I want to profile my iOS app when it starts up from the user swiping a push notification, from the not-running state.
How do I set up Instruments to attach to a particular app as soon as it starts up on the device (as opposed to starting the app via the "Profile" button in Xcode)?
You can change the process target in Instruments to "All Processes" on the device and then filter down to just your app.
I named my example app test in the screenshot above.
