So I have a working app that sends notifications every day reminding you to mark something complete. Right now the problem is that even when they have marked all requirements, they still get the notification. Is there a way to conditionally fire a notification? For example, only fire the notification if A==false.
If the user marks all requirements, remove the corresponding notification from the notification center.

cancelAllLocalNotifications() will as the name says, cancel all local notifications.
Consider that the phone has received a couple of notifications while the screen was in locked state. And we are only have interest in notifications received when the user actively are using the phone.
Is it possible to only clear these notifications from the list in the Notification Center, but without cancelling them?
If you can use identifier for description your every notification, than you can only one notification removing, after this process you can setting notification again. I think this kind a trick working for your situation.
I would like to know what is the best approach to do if I want to fire notifications for more than one time each day everyday.
I did some research and read that notifications for the next day cannot be fired unless the user opens the app the next day and updated the notification. Is that true? is there anyway I can do it without the need of the user opening the app everyday?
Thank you
You can schedule up to 64 local notifications. There is no limit on the time period; you can schedule them years in advance if you like.
That said, if you need some mechanism to schedule new notifications, even if the app is not running at all (e.g. because the user terminated it), you need a background mode for that. Fetch is probably the way to go here, as it doesn't need a special trigger. You could also send silent push notifications in order to wake the app, make the calculations and schedule the new notifications.
I have a problem scheduling UILocalNotifications.
My case is this: when user selects motivation category there is a dialog screen where he selects how many times in a day, week, month, motivation message should be presented to him. Then he selects time period: a day, week or a month. A motivation category has messages, and every category has different number of messages.
So my question is: how should i schedule those notifications? Main problem i think is that there can be more than one category. Can someone tell me how to do this?
I know that i cant schedule more than 64 notifications, so i cant schedule all notifications when category is selected. And i know i could reschedule notifications in
application:didFinishLaunchingWithOptions:
or
application:didReceiveLocalNotification:
I hope i have been clear about my problem.
First write a function that manages the local notifications
that is it has to check if there are 64 notifications scheduled if not then you may add some notification.(you have to handle DB part well for example setting the flags correctly)
Call the function in application:didFinishLaunchingWithOptions: just in case some notifications are expired or missed
You have to call the function in all the places where local notification is handled.
The user taps a custom action button in an iOS 8 notification.
In this case, iOS calls
application:handleActionWithIdentifier:forLocalNotification:completionHandler:
You also get the local notification object, so that you can retrieve any information you need to handle the action.
The user taps the default button in the alert or taps the app icon.
The system launches the app and the app calls its delegate’s method, passing in the local notification object
application:didFinishLaunchingWithOptions:
The notification is delivered when the app is running in the foreground.
The app calls the UIApplicationDelegate method
application:didReceiveLocalNotification:
Reference1:
Reference2:
I hope this helps.
If it doesn't cover your problem feel free to ask doubts
It works as pool when you utilized all your available notifications then you need to reschedule the free notifications in
application:didReceiveLocalNotification: but every time you are gonna reschedule you can find next notification to user that could be in today, tomorrow. Whenever you are in application:didReceiveLocalNotification: findout when to notify next and schedule.
I have implemented the Push Notification Successfully in the application, and I need to provide an option to user Where they can set the time for not showing receiving notification. all other time they can receive. I am storing the detail of their Do Not Disturb time in the database in the backend. I just want to check when the notification is fired. the current device time of user. and if that falls under their DND time. Notification is not to be shown and event the sound is not to be shown. Even in the Notification Section.
Any Help will be appreciated.
You can get the the timezone of the device along with the schedule. Depends on the time you need to fire the notification from your server.
i.e, once you fired the notification from your server you can't stop it from showing
The previous posting on here regarding deleting notifications from the notification center claim its not possible to delete individual notifications, only all of them.
However individual notifications do get deleted for the reminder app - set 3 reminders to fire in a couple of minutes, when they fire go to the notification center, now select one, after the reminder app launches go back to the notification center and that specific notification has been deleted but others remain. So how is this achieved?
The Reminders app probably fires local notifications. Local notifications can be withdrawn, using cancelLocalNotification: on UIApplication.
(Additionally, push notifications when sent using the enhanced call (first byte is 1) supports an expiry parameter (when sending, not inside the JSON payload) that is supposed to mean that this notification, if not delivered by a certain date, should not be delivered. It is possible that this parameter is also used in a similar way to hide received notifications.
It is also highly possible that Apple's own apps do whatever the hell they want.)
When the user taps on the notification:
If the app was running in the background, you retrieve it using AppDelegate's method didReceiveLocalNotification.
If it wasn't running, then the notification can be obtained with the didFinishLaunchingWithOptions method. You just need to search the launchOptions dictionary for the UIApplicationLaunchOptionsLocalNotificationKey.
If you want to delete specific notifications which have already fired, specially when the user doesn't enter the app by tapping on the notification, then it's probably better to store them in NSUserDefaults so that you can still obtain them later. That approach is explained here.
