Web service advice for an iPhone app - iphone

I am currently working on an iPhone app that will have a user log in, enter a workorder or building, and the app will display workorder/building information. The user will then be able to edit some of the data and submit it to the server. The backend database is a MySQL server. What is the best web service to use for this situation? I've been reading about SOAP, JSON, etc. but I honestly haven't found a good description of the pros/cons of each and how well they work with an iPhone app. Any and all help (or links to useful reading) would be greatly appreciated!

Ruby On Rails or PHP is your best bet for the web services layer that goes between the phone and the MySQL and go for JSON as that is the most commonly IPhone Web service data format as it is the one that requires the least amount of data upload by the phone. Touch JSON is commonly used IPhone framework for this.The RoR or PHP web services layer serves up JSON data based on URL requests by the IPhone. There's loads of stuff on this if you google which I did when faced with a similar problem.

Can a ionic app fetch data to a website's database?

i was planning to make a project out of my curiosity , to make a ionic framework mobile app that fetches data from a website's database (which i already made). Is it possible? How? i have no idea how to do that because im still on the learning process(novice)
Yes you can do this and its possible. First of all you need to create a connection that you Ionic App can communicate with your Website.
That is Called an API. If we dont use any big tech Words to explain this.
The Common practice is build a REST-API first.
Its a Link, and when you goto the link, the link will give you data in a Format JSON or XML. So your App can Parse the JSON/XML Data and display in your Ionic App.
Example.
www.yourwebsite.com/getusers
www.yourwebsite.com/adduser
you will call the first link from your App in GET protocol and this will give u a list of users in JSON Format.
you will call the second link from your App in POST protocol with User Parameters and this will add a user and Will give you Success or Error Json/XML Response.
So first you need to learn a bit about REST-API and how to build them. You can build them in any language.

Then plan which language is the best for you and follow up a good tutorial.
And Finally follow this on how to call an API from IONIC
CALL API FROM IONIC

A web service is a service offered by an electronic device to another electronic device, communicating with each other via the World Wide Web. In a Web service, Web technology such as HTTP, originally designed for human-to-machine communication, is utilized for machine-to-machine communication, more specifically for transferring machine readable file formats such as XML and JSON

Application users account registration and login, best way to handle?

First of all, i'm new to Objective-C, so please be patient with me.
I want to add to my application users account management, users can register/log-in into a personal account that will synchronized with database on the internet. I dont have a clue how to do that. I know how to work with sqlite3. I was thinking maybe to create an sqlite3 database on the device. is it possible to store images into sqlite3 database? is it the best and efficient way to manage users on application?
what does sign in with Facebook or Twitter do? is it possible to add them both and another option for someone who doesn't have Facebook or Twitter?
What is the best way to handle account registration and login on iPhone?
Thanks alot!
I want to add to my application users account management, users can register/log-in into a personal account that will synchronized with database on the internet.
AFNetworking or ASIHTTPRequest can help you with this. create a web service api, maybe in php + mysql or any web scripting language you prefer, from the device you can POST your data like username and password and do the logic in your web service.
I was thinking maybe to create an sqlite3 database on the device. is it possible to store images into sqlite3 database?
what is your plan here? why would you create a database on the device? do you want to manage the users locally? if yes, that would be easier and more efficient because you dont need internet connection to create a request to server. and yes its possible to store images in sqlite by storing the image as blob
what does sign in with Facebook or Twitter do? is it possible to add them both and another option for someone who doesn't have Facebook or Twitter?
Yes its possible. you can have three log in options. facebook, twitter, and your custom log in option. if you want to integrate facebook and twitter on your app. there are many tutorial and docs you can find there.
I suggest: this for facebook and download the sample app
What is the best way to handle account registration and login on iPhone?
it depends on your app requirement, if you dont need to store your user data in a database on a cloud server, the best way is to create a local database on device.
This is a broad question - so the answer is going to be very general, little of which has to do with Objective-C, iOS, or Mac specifically.
It sounds like you are creating an application on a mobile device that needs to synchronize data with a database for which the mobile app is a client. One way of managing this is to start with table of users and credentials on your server, e.g. in MySQL. Then you need to write the API on the server side, e.g. in PHP, Rails, Python, etc. Then you will write the web service code on the device that interacts with the server's API.
If you are new to developing on iOS, then I would suggest running through some tutorials on consuming web services, first. That is, I would learn how to connect to pre-existing web services first. You might want to check out the AFNetworking library for Mac and iOS. It has some demo applications. But if you want to stick with the native URL loading system on iOS, there are numerous tutorials available. (Here's one)
I should mention another option is to use Amazon Web Services SimpleDB. There is an iOS SDK. It allows you to execute queries directly against the db without writing the server-side code.
You mentioned sqlite3. This will allow you to manage data on the device; but you state that you want to sync data with some resource on the internet. You can store images in sqlite3; but you can save yourself a lot of hassle by looking into Core Data as an alternative.

iOS app to access database from my own website

I own a JSP website for listing books stored in my own database in the same website. I'm planning to develop an iPhone app to access this database and display book list and book details.
My questions are:
If I have to use web services, where
should I start to develop these web
services using eclipse.
How to access these data and display
them in a list.
I want to cache data extracted and
store it locally in iPhone, so when
no Internet connectivity available
the user can view these data
offline. Is there a database engine
embedded in iPhone to sotre such
relational data.
Thanks you all,
Develop the webservice with what you know. PHP, Python, asp.net, java.
Access the data using HTTP GET POST methods. Many application are using the json-framework.
iPhone as the sqlite3 database embed in it operating system. You can find plenty of tutorial on the internet.
1 & 2 Define the services you are going to provided from you website, choose a web service protocol, JSON is generally easy to use, so does xmlrpc.
3 Use core data to cache it locally, if no internet connection, you can fetch the data from core data

objective-c iphone programming : remote connection database iphone

i simply want to make an iphone application with a remote database. For exemple facebook iphone application, they have all access to a huge database. Are they using Mysql ? Because i heard that mysql is not secure through iphone and app store may reject it. Can someone help me figure out whats the best to use.
What all those apps are probably using is a RESTful web service endpoint that is in turn backed by a large database. There are a lot of libraries for creating web services regarding of what application stack you're using.
If you're using MySQL, you'd write a Python/Ruby/Whatever-you-choose backend component which actually connects to a MySQL instance, then reformat the results as a web-service endpoint. SOAP can work if need be, or (in my opinion) a better option would be to write a simple JSON service that your iPhone app can parse. There are lots of JSON/WS iOS libraries that are a google query away.
Apple will not be bothered what database you are use remotely (will be accessed through defined API's).

Hosting a web service for an iPhone App

I need to write a fairly simple Delivery Tracking application. The device needs to know information about the 'matters' such as status (delivered/awaiting delivery), type (for delivery/for pickup), address, payment accepted etc.
The iPhone part of the app seems very simple but in terms of hosting some kind of web service is the part I am unsure about.
Does Apple have some kind of service or recommending way of handling this?
The web service would need to store all the information about the matters and receive updates from the device when matters are delivered and then there is a possibility that new matters could be sent out manually from the depot.
These are the parts I am unsure about - any ideas?
There is no Apple recommended way or service. For a similar system to the one you are proposing I have a Ruby On Rails (http://rubyonrails.org/) backend application with MySQL database hosted by a third party. It took me a couple of weeks starting from no knowledge of RoR to get the Rails App and database up and running. I recommend Appress's Beginning Rails 3 as a good book to start with. You can develop and run Ruby On Rails on MacOSX and easily port your app to a Linux server when it sufficiently developed.
There are other web-services frameworks such as PHP or ASP.NET which you could use so long as they return data in the form of JSON or XML.
The Ruby on Rails app can render JSON or XML when the iPhone app sends a request via NSURLRequest. I'm using Objective Resource (http://iphoneonrails.com/) which takes care of a lot of work connecting to RoR backend but you can use the many open source JSON frameworks such as TouchJSON (http://github.com/schwa/TouchJSON) or use NSXMLParser, an Apple Objective-C class, if your request returns in the form of XML.
