I have been using iOS client https://github.com/robbiehanson/XMPPFramework
successfully install ejabberd on client side and enable the archive mode on server, able to send and receive message.
My problem is how to get older messages and sync to my local core-data. I have read the framework support and it partially support XEP-0136.
I will able to make any custom APIs from server to fetch the messages and sync on the local.
But i did not get any common message id or so on that basis i will sync.
If anyone has idea about syncing. please let me know.
hi i have done many thing in xmpp from (http://xmpp.org/xmpp-protocols/xmpp-extensions/) tutorial you can get example from bellow github links you can get many help from that
(demo links: )
https://github.com/sesharim/ios-jabber-client
https://github.com/funkyboy/Building-a-Jabber-client-for-iOS
(xmmp Project demo Link:)
https://github.com/chrisballinger/ChatSecure-iOS
i hope it will help full you..
you can get how to fetch old messages and user list and other detail from that above demo programs.
Read XEP-0136 carefully - it describes how to retrieve existing archive.
In fact, XMPPFramework already implement storing all plain incoming messages - you just need to initialize XMPPMessageArchiving with XMPPMessageArchivingCoreDataStorage and activate module on your XMPPStream. Then you may perform core data fetch requests on [XMPPMessageArchiving mainThreadManagedObjectContext]. If you want to retrieve previously archived messages - you should extend XMPPFramework a bit:
send <list ... /> query, optionally limited with Result Set Management parameters (which is supported by XMPPFramework too)
process result (which gives you archived collections by user jid and timestamp) and ask for interested collection with <retrieve ... /> query
process result and send [XMPPMessageArchiving archiveMessage:] with each message in result set, and XMPPFramework will do the rest job - inserts in core data storage - for you.

I'm been coding for a year now and know swift really well and the basics to javascript. I've built a social media like app and its completely done besides the push notification functionality... which i've been struggling with for quite a while now.
I'm having trouble figuring out how to implement these in order to send notifications like when a user follows another user or they receive a new messege.
I don't understand how to integrate the cloud functions that I would write using and node.js with my xcode project.
When I look for documentation online its usually just how to send push notifications using the firebase notifications console which is cool but doesn't trigger based off specific user actions or events (ex: when the user gets a new follower)
I think since im struggling with grasping the concept of how to implement it, the actual technical set up of it makes even less sense. Any advice or resources would be greatly appreciated.
Thank you
Conceptually, what you have to do is set up server-side processing of your database to manage when events occur. This is what the Node.js code will be. Everything is connected through the database-- your Xcode and Node.js code work independently, but both communicate with Firebase. You can create a Cloud Function that will automatically run when it detects changes in your database, and this will automatically send push notifications.
I've done a similar project-- I set up a listener for my Realtime Database in my Cloud Function. Every time the user got a new follower, i.e. their followers tree was updated, I sent a notification to the device using an FCM token (which I also stored in the database).
exports.onTimeEnd = functions.database.ref("users/{user}/followers")
.onUpdate((snapshot, context) => {
// your code here
}
In that block, you can call a .once() to find out the user's token to send them a notification with.

This link here told me everything I had to do in regards to set up in the terminal. Super helpful.
Just a quick question if anyone has any insight / knows any good tutorials or guides. An ios app I am making consists of user-generated content and because of App Store rules, it must provide the user with the ability to report offensive/illicit content.
When the user reports something, my app creates a node with all the information of the report on the Firebase Database. Now, I could just review by using the Firebase console, but this would be very tedious so I'd like to implement some code that, whenever a node is created under "Reports" gets all the data from the database and storage and sends it as an email to a given account or stores it in an easily reviewable format.
Does anyone know how to implement this sort of backend code?
Thank you
This sort of situation is ideally suited for Cloud Function for Firebase, which allows you to run small snippets of JavaScript code in response to events such as a node being written to the database.
I recommend that you have a look at the Cloud Functions for Firebase documentation, specifically at the list of sample use-cases and even more specifically at the sample of sending a confirmation email when a user signs up for a newsletter.
I'm new using the Firebase Cloud Message. I built an IOS app to receive push notifications. The app works fine. I send messages from the Firebase console and they're displayed correctly.
Now I`m trying to build an web api to allow my customer to send the push messages (without accessing the firebase console). Studying the documentation here I realized that I've always to have a "to", meaning a group, topic or device id.
My question is: can I send a message to all devices (like I can do in the console)? I yes, how so?
Thanks in advance!
You can make use of topics. Given that all of your users are subscribed to a specific one. Just like what I mentioned here (removed some parts, just check them out if you want):
If you are looking for a payload parameter to specify that you intend the message for all your users, unfortunately, it doesn't exist.
Commonly, when sending notifications to multiple users, you can make use of the registration_ids parameter instead of to. However, it only has a maximum of 1000 registration tokens allowed. If you intend to use this, you can make batch requests of 1000 registration tokens each, iterating over all the registration tokens you've stored in your app server.
However, do keep in mind that Diagnostics for messages sent to Topics are not supported.
I found this:
!('TopicA' in topics)
With this expression, any app instances that are not subscribed to
TopicA, including app instances that are not subscribed to any topic,
receive the message.
So you could probably use
condition="!('nonExistingTopic' in topics)"
I want to store only 20 Notifications which include
"Title,Detail and Received Time" fields inside Notifications Table.But,I only found solution for working CoreData with CRUD some example.But,I am still seeking for working with limitation when user fetch new results from api inside device database.That is where I am stuck.I don't know how to do it using CoreData because I was beginner at that.
Requirement :
1.Application can only store 20 Records maximum.So,when it reach max length,it will do First-In-Last-Out to Notifications table base on Notifications Received Time.(First Problem)
2.Every time the user do pull to refresh,my app fetch new notification from Web-Backend and replace or overwrite on user device database when it successfully download new notifications like "Push Notification Service App" on App Store.(Second Problem)
I really need a hand to pick up with core data flow which I am stucking at things I am not familiar with.
Any help or guide please?(Posting Sample with .json is appreciated)
use NSUserDefaults for that if your data size is small
Consider using a service, like RestKit or similar, to support your web service interaction. Each record should have a unique identifier supplied by the server so you can find an existing copy and update it instead of needing to delete everything and recreated it.
To trim your data use a fetch request with a fetchOffset and a sortDescriptors by date. This allows you to skip the newest 20 items and gives you a list of everything that needs to be deleted. If you're using RestKit you can supply this fetch request in a fetch request block and the deletion will be done for you.
I'm working on an iOS application developed with Swift. The application is going to need notifications to receive alerts when certain events occur.
To handle push notifications I'm using parse.com. I was able to create an account and integrate push notifications into my application, as it's explained in the Parse.com guide, and are working fine when I send something from the Push section.
What I'm trying to do, and I cannot figure it out, is consume a 3rd party JSON, process that JSON to check some status and report, to the users that are using the application, a status change via a push notification. I know I should process all this in the backend/server side and then push the result or what I'm trying to notify, but I don't know what to do.
Ex. of What I'm trying to archive:
3rd party website ---(json)---> parse.com ---(push notification)--->
My App
I'm aware the tools that Parse.com provides, such as REST API, Cloud Code, Webhooks and Jobs, but I'm totally lost here! I cannot find any guide or documentation that allows me to do what I previously described. I don't even know if its possible, and the documentation at parse.com it's not necesarily up to date.
I hope anyone can help me, or guide me, if parse.com it's not enought for my purpouse.
Thanks for reading.
I would suggest looking into Cloud Code or a Job from Parse and seeing if you can get one to run on a time interval to look for updated JSON.
You can decode JSON using JS, which is exactly what Parse Cloud Code is, you actually write it out on your own computer and then upload it. I've only use the afterSave functions. I would think you probably have to keep some type of object in parse to see what is updated and notify who ever needs to notified when that data is updated.
Also, you'll probably want to pass something to the app to actually update when the user selects the push alert. You can do this in the push alert itself. It converts to a dictionary in the app delegate's method for handling received notifications or launching with one.
Alternatively, if the web server is under your control, you can create a PHP script that will trigger the push to parse.
My best shot at this (after not having used Parse for a long while) would be to set up a Job on Parse that queries the 3rd-party service, and takes that response and throws it into a Cloud Code function, which in turn parses out that JSON and sends off a notification.
Parse's reference materials would probably be a good starting point.
The toughest part for you is the up-to-date-ness of your data. Since you're still polling that 3rd-party service at a regular interval, it's going to be a trade-off between freshness of updates and frequency of jobs (which cost money at a certain scale).
