I'm working on a project on iOS 7, 8 that use a lot of notifications (Remote, Local). I have some questions about Local Notification.
I'm using Local Notification to schedule an alarm or a count-down. As I know, the use of NSTimer is not really a good choice since it has only up to 10' in background & if the app process is killed it doesn't work anymore. Local Notification is managed by iOS but I have to accept its alert when the app is not in foreground. There's nothing like silent local notification (local notification without alert, sound or badge and app still knows about it although it's in background). Am I right ?
Let's assume that there're some simple local notifications in Notification Center, scheduled by our app. Normally when I touch on a notification to see it in my app, the others remain present until we interact with them. In some cases that I haven't figured out, all other notifications are removed from the Notification Center. Does anyone encounter this & understand why ?
I find the interactive notification feature in iOS very limited. I want to change the title of a defined UIMutableUserNotificationAction button & add an image for it, like I can do with UIButton. So the question is : Is it possible to customize the UI of an action button ?
Thanks for your help !
Unfortunately there is no correspondence in silent notification using local notifications.
The number of the visible notification in the notification center is a user decision, the user in Settings can decide to set a different number or decide to do not show them in notification center as well. As for the first point no. The third point is not clear, you can set the image you want for a remote just put in the payload the right name, local notifications use the app icon.
There is no silent notification for Local Notification. The user has to click to the notification to open your App.
I suppose that the associated application has deleted those notifications programmatically. Else, those notifications must stay in the notification center.
You cannot add image to action buttons but just the titles.
I tried more than two weeks to do the same. I had to show notification after 2 hrs even if the use doesn't click the notification. But the repetition facility is well handled in objective C. I could have created multiple local notification but it will also violates the total number of 64 notifications. Apple needs to improved the same.

My application is currently set up to display local and push notifications even when in the foreground. There is one specific local notification I would like to disable when in the foreground, but keep enabled when the app is not active or in the background. Is there a way to accomplish this?
When app in foreground iOS will not show notification banner/alert by default on its own, you must have written code or used a third party frameworks to show some banner on App, just put a break point in that code to not to show the specific notification

I have my application developed on iOS 8 . I have implemented push notification in my application. In iOS 8 clicking on notification automatically clears that particular notification. But my requirement is notification should stay until clear manually. Please give suggestion how to achieve this.
This is a system behavior. You can not prevent this to happen.
If you need something to be always visible from the notification center, consider to create a Notification Center Widget.
I use a phone gap plugin and xcode 5.
Lets see the example of the problem:
The application is in background or closed.
I send the notification.
User sees the notification pop up, without clicking on it.
I send another notification.
If user open notification bar it will see two notification actually i want
to delete the previous some how and present to user only the second notification.
The eqvivalent in java is NotificationManage.cancelAll();
For now each/all notification i send are shown when user open notifications bar.
Any help appreciated.
You have (the app has) no control over that.
The user controls how many notifications they see in notification center. Notifications can be removed by the user and will be removed when acted upon (the app is opened from the notification).
You can do this by [UIApplication sharedApplication].applicationIconBadgeNumber = 0;
in the method didReceiveRemoteNotification. In this way notification center will be cleared.
Got 2 questions for the xcode experts :
- I would like to send a (repeating) local notification only to the locked screen but without having the screen turning on, it is possible ?
- I also would like to check whether the screen is on or off (for this very purpose) : is there any way with the current IOS version (IOS 7) ?
Many thanks for any help !
No this is not possible, frits it will be very hard to get you app running in background without misusing one of the background modes.
You cannot detect if the devices is locked and you will flood the notification center with messages.
If you do manage to get it working then there is good chance that Appel will reject your app for doing this.
You can check the screen by checking the applicationState property, which will be set to UIApplicationStateInactive when the phone is set to lock/sleep (as opposed to UIApplicationStateBackground).
As for the notification, you can set a push notification delegate (I've not done it from scratch, but I did it using Urban Airship and creating my own custom push handler class) and handle whether to post an alert or not there. I'm not sure, though, whether having the phone sleep will kick notifications to the OS level, which would default to showing a notification on the screen.
Ok, so I've wrote a small app that receives remote notifications that I handle in didReceiveRemoteNotification and I also check the userDict passed to didFinishLaunch.
However, the notifications is sill listed as "unread" in the notification-center on iOS 5 (there is a tiny blue dot to the left of them). How can I make it so that after a user has clicked a notification it either goes away, or it's marked as read?
I don't think there is a way in iOS 5.0 to only remove one entry. Quoting iOS SDK Release Notes for iOS 5.0:
Springboard
Push and local notifications for apps appear in the new Notification Center in iOS 5. Notification Center displays notifications that are considered "unread.” To accommodate push and local notifications that have no unread status, set your application’s badge count to 0 to clear that app’s notifications from Notification Center.
