Update badge counter in Swift

H

22

With following code I get (2) in the badge icon immediately after app compiling:

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    let installation = PFInstallation.currentInstallation()
    installation.setDeviceTokenFromData(deviceToken)
    installation.badge = 2
    installation.saveInBackground()
}

I did try the next variant: Initialized a new var badgeCount = 0 and later:

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    badgeCount++
    let installation = PFInstallation.currentInstallation()
    installation.setDeviceTokenFromData(deviceToken)
    installation.badge = badgeCount
    installation.saveInBackground()
}

But when I get new notifications it doesn't update to +1. Is anyone know how to fix it?

Can you please share your code and your Parse settings because it seems you resolved your issue and I have the same question but I can't fix it. I don't use Parse at this time but if you can success the update badge count I will use it. Thank you very much. – Kura 29/6, 2018 at 10:4

It won't update the badge number with this method unless the app is actually open. If you want to update the badge number upon receiving a notification then you need to set the Badge property of the json push notification to the desired number.

If you, if you are sending a normal message (not using json) there is a toggle to increment the badge number, just tick that. If you're using Json then use this:

{
    "aps": {
        "alert": "Test Push Notification",
        "sound": "yourSound.aiff",
        "Badge": "desiredNumber"
    }
}

Please note, if you do not wish to send this from the server, you can also send it from one device to another utilising Parse's client push, go into your settings in the app on Parse.com and enable "client push", you can then send the above Json to another user's device.

how can I send it from the server? How can I know how many notifications are unread? – Homogamy 24/4, 2015 at 9:11

I looks like you're using parse.com right? If you, if you are sending a normal message (not using son) there is a toggle to increment the badge number, just tick that. If you're using Json then use this: { "aps": { "alert": "Test Push Notification", "sound": "yourSound.aiff", "Badge": "numberYouNeed" } – Hamadryad 24/4, 2015 at 9:13

No, I use Pase.com. Can you tell me how to do it? Increment the value of badge – Homogamy 24/4, 2015 at 9:14

I just have done, check my last comment, i have also updated my answer – Hamadryad 24/4, 2015 at 9:17

no, I do not want to send it from the server. In the Parse.com documentation gameScore.incrementKey. Can I use it? – Homogamy 24/4, 2015 at 9:19

This is the answer - just take a moment to read what Swinny89 has actually posted. Swinny89 - you may with to edit your answer with your comment – Mirabella 24/4, 2015 at 9:22

@Mirabella I do not want to send this number of badges from the server in JSON. I want to increment it after every notification if it did not read. If read - I reset it to 0 – Homogamy 24/4, 2015 at 9:24

Read the first line of my answer again – Hamadryad 24/4, 2015 at 9:26

your version just changed it to 1 and didn't increment it later. How can I increment it? I did send it as JSON – Homogamy 24/4, 2015 at 9:31

Lets start form the beginning. How are you actually sending your push message? From parse.com under the push section? – Hamadryad 24/4, 2015 at 9:33

Make sure message type is set to plain text, increment badge is yes, type your message and send it. If the app is not open then the badge will be updated for you. Upon opening your app, or whenever you need to, make sure you set the badge back to 0 using UIApplication.sharedApplication().applicationIconBadgeNumber = 0 and also using currentInstalltion.badge = 0 and then saving it in the background – Hamadryad 24/4, 2015 at 9:41

Whenever code is compiled it shows the badge icon which is previously store in your app. If you don't set the badge icon = 0 in your app it will show the badge icon number in your app every time you compile it or enter in background state.

Now for your problem, use badge icon as

var badgeCount = 0 

 UIApplication.sharedApplication().applicationIconBadgeNumber = ++badgeCount

Also whenever you are done with your task make badge icon as 0 otherwise it will show a badge icon in your app

UIApplication.sharedApplication().applicationIconBadgeNumber = 0

I paste it inside of didRegisterForRemoteNotificationsWithDeviceToken like:

let notif = UIApplication.sharedApplication() notif.applicationIconBadgeNumber = ++badgesCount installation.saveInBackground()

and nothing again =/ – Homogamy 24/4, 2015 at 9:36

if you don't make badge icon = 0 it will show all the time – Octaviaoctavian 24/4, 2015 at 9:44

please describe your application flow so we can adjust icon number. for example initially it is 0 when push notification it increment and after some task decrement – Octaviaoctavian 24/4, 2015 at 9:51
