I am new to swift and was wondering how could I send commands from a server to my iOS application ? For example imagine a website where I can click a button and that button would then trigger a pop up to all users of my app. Is this possible and if so can someone lead me in the right direction?
Much appreciated
Yes, you can
Silent Push Notification: Send a Silent Push Notification and handle in your app. But you need user permissions to receive Notifications. Add "content-available" : 1 to your notification content.
Using Sockets: There are many options to create connection b/w device and server. example: https://socket.io/
It depends what you are trying to do, you might want to look at apple push notifications and see how they work. From there I would suggest looking into sending notifications to the apple server (that would send the push notifications to the app). I hope this sends you in the right path good luck!
I just assume that you have an application that a number of users are using and you have a web application that can show all mobile users.
For the most of cases, whenever a user is using the application, you let the application send a request with your user's information to your server and your server records the user information in the database.
When your website wants to show all the users' information, it just fetches all the information from the database instead of sending sort of commands to all applications to get information in real-time.
Of course, there is a more complex way to send commands to all running applications to get the results. However, it requires both server-side and client-side (ios application) implement functions sending commands in real-time using Socket or MQTT etc. This is more complex and it requires iOS application running in front or background at the same time.
I assume that using HTTP to record every mobile user is more suitable for your case.

I have to make an application that receives commands from a website and therefore perform an action.
I thought about creating a login in android to send the username and password for POST and if this is correct, the web server will return a unique token. That would serve me later to send information to the server and ensure authentication...
But ... how can my android application know when the website has a warrant for?
I've thought about that all the time is pending a URL "checkOrders" and if it finds your token, request orders to another URL
Anybody know other method to make it?
If I understood your question correctly, the only (battery and otherwise) efficient way is using push notifications. Unfortunately, this approach is not even close to being simple.
Since you're developing an Android application, you may want to consider Google Cloud Messaging and Parse Push. If you're planing on developing apps for iOS and Windows phones in the future, I'd strongly recommend Parse Push. At the moment, it's free for up to one million users.
Hyperlink for GCM will lead you to generally useful reading on this topic. That's why I am not elaborating here.
I am trying to code a messenger service that will store sent messages in a server and then push the message to all devices connected to the server.
The messenger will be used in a classroom environment and the messages will never be sent to one individual device. At the moment a message can be sent and stored in the database but the app needs to be refreshed for all the messages to be displayed. A simple way would be to continuously run the stored procedure but that would require extra bandwidth and i'm sure there is a better way to do it.
I am currently coding in Android Studio and I'm using MySQL as my database and PHP for my stored procedures. I am very new at Java and this type of coding so any help will be appreciated.
Thanks
Yes, what you are suggesting is named "polling" => check if the server has some updates each 10sec or something like that. You're right, it's evil (drains the battery, use a lot of bad=ndwidth, etc.)
What you need is a "push" service. If you are working with Android, the easiest way of doing it is to use GCM (Google Cloud Messaging) : http://developer.android.com/google/gcm/index.html
This little guy will provide you a way of notifying all the devices that theure have been some changes on the server.
It's pretty well done (if it can't reach the devices, it will try again with an exponential time delay, etc.).
You can use google cloud messaging service to send notification in device so please register your application on google service all step are cover below link.

I need to send push notifications to my app from my server and i am thinking to use urban airship and i am using PHP at back end. As much i got from urban's documentation ,my server need to send message to urban's server and urban's server will forward it to devices
Now ,i want to automate the process of sending of message from my server to urban's server. Actually, at my server, i am executing a script that go through database and fetch list of users to whom message need to send. so please guide me regarding automating sending process.
Yeah, you can use UrbanAirship (UA) for that. They provide a REST API (http://docs.urbanairship.com/connect/index.html) you can use to send to your audience (UA slang for your users).
So you basically just have to
use UA SDK in your apps. Basically, they will take off when you start your app, register with Google / Apple for push notifications and give you back a token that you have to store in your database
Handle any event where you want to send push notifications in your script
get call the data for the users from your database, i.e. the device type (android / ios / windows phone) and the token you received from UA for that user
send the data to UA in the way they want it (http://docs.urbanairship.com/connect/connect_send.html) and your good to go
If you want to run your script periodically I would propose just using a CronJob (https://askubuntu.com/questions/2368/how-do-i-set-up-a-cron-job) that runs every X minutes / hours / days
I am writing an IOS app that is basically a jabber chat app. I am using Openfire for the xmpp server and so far its been great. The problem I am facing now is with push notifications. The app is written in Xcode which gets user data from a PHP Api. Openfire is the xmpp server. The issue is that when the app sends a message to openfire I would need to also query the Php api to see if the user is online and if they are not, send a push notification. This would have to happen for each message sent and as you might guess that will affect performance with all those requests happening.
I have everything working, I just cant get past this hump. If only openfire would fife off a request of my choice upon receiving a message.
Can anyone suggest a better idea? Basically need to know if the user is online (presence) before so that I know to fire off the push notification and I dont want to fire off two requests from my app per message sent. Thanks.
In openfire the messages to offline users are stored in ofoffline table. So your php code neednot worry about the status of the user if der is any entry in the ofOfline table it means the user was offline. Now create a scheduler that will keep looking in the ofOfline table for offline messages club them together and push notification to the user
i have spen lots of time for in XAMPPHP Library but cant find any proper solution. so for develop a web base chat application with jabber server. rather than using XAMPPHP, you can use "http://strophe.im/strophejs/" it will be much faster than XAMPPHP and you can find more js plugin for Strophe js. and you can also find more ready made xmpp client base on strophe js. so it will better than XAMPHP.
I need to make chat application for android. I thought of using PHP script to implement the chat application. Basic idea is to send message form android client to PHP script and making use of PHP script send the messages to the MySQL database. These messages will be broadcasting to other people. But the problem is auto broadcasting messages to other people. Is there a way to do this using android and php?
You can do the following
Make a persistent tcp connection between your device and the PHP server
When a message is broadcast send it over the tcp connection of each device
On the device process this notification and you are good to go.
If you want to use Java on the server side I have your project already finished and ready to ship ;) (just kidding)
But if you are interested check out the Device-To-Device messaging framework of OpenMobster Mobile Cloud platform. The project is free and open source. Here is a link to the Device-To-Device Framework: http://code.google.com/p/openmobster/wiki/D2DPushFramework
and http://code.google.com/p/openmobster/wiki/PushFramework
The above three steps are already taken care of by the framework. The developer just has to focus on the App itself
Good Luck!!!!
Yes there is several ways to do this
you can just post to the server and from the server send push notifications to the mobiles
You can make the mobile keep checking for updates if it exists
You will require to finish these steps ( at least ):
setup a PHP web server
register for Android Push Notification (you probably need that)
create database schema
write your own codes to allow users to submit & retrieve chat messages
security !!!
You'd probably want to use Google's C2DM, though it's not free.
Your php server would get a message from a phone, do it's processing, then make a HTTPS request to Google's C2DM service, which sends the messages to the destination android device.
http://code.google.com/android/c2dm/#push-process
Don't use C2DM, its a deprecated. Please go through the GCM(Global Cloud Messaging),

Have you heard of Firebase? Firebase. Making a chat app with Firebase is like eating pizza.
