Question:
Is there a way to detect if you get a system notification and you swipe away the notification banner (e.g. the alarm that triggers a system notification)?
More practical example:
In your app, you are doing some stuff and suddenly you get a notification from another app. Instead of tapping on the notification, you swipe up the notification (you dismiss it that way). After doing that, I want to capture that in the app.
Why:
Currently, I have a bug in the app, so if I can capture this action, I would be able to fix this bug.
Thanks in advance!
When notification appears, the willResignActiveNotification won't get called, therefore willEnterForegroundNotification won't get called, too.
The best solution here is to catch incoming notification and show the custom view describing this notification instead of system one. Thus, you can detect all actions/timings you need.

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).
Do I want to know if it's possible to detect when a notification from another application is over my app? For example, when the user receives an SMS or Messenger message. Detect the fact that a notification is present on the screen. I don't want the content of the message.
It's an example, It can be a notification for whatever. Because, when a notification is visible, my player's lost because a part of the UI is under the notification. So, if I know when a notification is visible I can change the layout.
It's not possible to handle notifications from other apps. It would be a huge privacy violation.
In swift 3, how can I handle a local notification while the app is in the background and before the user taps on the notification?
UserNotificationController.userNotificationCenter(_:willPresent:withCompletionHandler:) is only called when the user taps on the notification.
My goal is to create a local notification that displays a screen similar to an incoming call in which the user can swipe to pick up or hang up.
Thanks!
According to this SO question, it's simply not possible:
iOS Local Notification - Callback when in Background
Quoting part of the answer given in that link:
If your app was in the background or not running, and the user does
not tap the notification and summon your app, you will get nothing at
all and will have no way to know that the notification fired. This is
because notifications are not for your benefit but are a way of
sending a message to the user. (It sounds, from your question, as if
you may be misusing local notifications as a way of sending a message
to yourself. That is not what they are for.)
Target: 7.0 and UP
Testing on: iPhone6 Device
I have been testing Regular Push Notifications (Remote).
I have discovered that if a user clicks on the app icon -- the "applicationDidFinishLaunching:" method is never called.
I have been reading and re-reading the guide on "Handling Local and Remote Notifications" and to confirm that I understood everything referred to: Handling Remote Notifications
It says If a user taps the default button in the alert or taps (or clicks) the app icon, then the app should call its delegate "application:didFinishLaunchingWithOptions" method. And if its a remote notification, it should call "application:didReceiveRemoteNotification:fetchCompletionHandler:".
Neither one of these methods get called if I click on the app icon.
The only method that does get called is applicationWillEnterForeground.
I do have a storyboard file. So the way it loads:
--> navigation controller --> table view controller --> so on
Am I supposed to somehow set the appDelegate in the storyboard file?
I have done a lot of research and so far I have had no luck.
My push alerts do come through so I know that it works. I just haven't been able to determine why these other methods are not being called when the user clicks on the app icon.
Any suggestions or help is appreciated.
The only solution if you want to handle when a user clicks on the app icon is to either A.) set up silent notifications or B.) Set up something on your server so that you can make a request to it to find out if there was a new update.
I am using push notifications in my app and I would like to send user to particular view, not the view he last saw. Is it possible?
You need to implement the appropriate AppDelegate messages.
Specifically, you will receive the APNS payload on the application:didFinishLaunchingWithOptions:
You might also receive the payload in a different message, application:didReceiveRemoteNotification: if the application is active.
Then when you know that your app was launched because the user touched a notification, you can direct him to a specific view accordingly.
I don't think that you have control over what the user sees while app is starting app (opening animation). After the app is fully active, you can send him wherever you want to by opening proper view controllers, setting proper tab, etc...
