I'm trying to write an iOS app using Xcode.
A simple login prompting username and password.
I have no idea how to open a database connection to validate the username and password.
The database I use is mysql.
I tried using this link http://macbug.org/macosxsample/mysql#.Ur8AYBbtGPF
but I get an error when I tried to add libmysqlclient.a to the frameworks and library.
If your database is on a server somewhere, then you would generally not have your iOS app interact directly with the database server, but rather you would write a web service that the app would interact with (via NSURLConnection, NSURLSession or something like AFNetworking), and the web service would interact with the MySQL database.
In terms of how to write a web service, often, when people are writing their first web service, they'll use some simple technology like PHP. Do you know what options you have on your server? If PHP is an option, then you can check out Ray Wenderlich's How to Write a Simple PHP/MySQL Web Service. Then check out How to Write an iOS App that Uses a Web Service.
You should use SQLite instead of MySQL for iOS application. You are referring MacOSX application tutorial. try this http://www.raywenderlich.com/913/sqlite-tutorial-for-ios-making-our-app

I want to create a class which connect
to a mysql Server to all platform (IOS Android and windows)
how can I do that? is there a DLL or an API to use
Do not connect your App directly to your database. This will cause a huge secruity problem. Use web services instead. The web services will handle the interaction between your client and server.
Web Services
And if you are just playing around or sth here is an example.
Example
I am a student and I am creating android app using apache cordova.
I want to access MySql Database of hosted website using apache cordova.
Please suggest me how can I do it.
Thanks in advance
For accessing that DB, you need to make a server API, you dont have to make it in PHP, there are a lot of technologies, but you can't do it directly from the client side (cordova).
Google for API REST or web service and choose your technology.
Im doing my final project which is a taxi booking service. i intend to make an ios app for the customer so that they can book a taxi. the request will then be sent to the mysql database (held at the taxi base). i want to no how can i send the information from the app to the datatbase; and the datatbase to send a confirmation message back to the app confirming the taxi has been booked!>>>>>
i have read a lot about web servers but am very confused. can i use an web server e.g. windows home server 2008? any help would be appreciated.
I am not familiar with Windows home server 2008, but I'm pretty much sure that you can use it for your project.
If you want to keep things simple,
Just install XAMPP server which comes with all the components you need to work on this project including PHP and MySQL. It is one of the easiest servers to work with and most of all, its free and open source. http://www.apachefriends.org/en/xampp-windows.html
Then write the business logics inside your Web App using whatever the programming language you want to (for this one PHP would be enough, or choose Java if you want to have a more complex scalable solution). Writing data to a MySQL database using PHP is very easy and you can find ton of tutorials and sample source codes in the internet.
Now your web app is all set, the next step is to expose these services using REST where an iPhone can communicate with your services. Use JSON for interacting with your Web server from iPhone. Again, there are tones of tutorials on how to write a JSON RESTful service using PHP.
Finally in your iPhone app, you can access the service exposed from the server for saving data as well as to retrieve anything from it through JSON. For making this, use a good Objective-C framework such as AFNetworking. It comes with the JSON parser as well. Ref. http://afnetworking.com
Good luck with your project !
RESTful web services are going to be your best friend here.
Create a server side program in django or python or whstever. Connect it to a database (mysql).
You can host it on Amazon Web Services. I think they have windows 2008 instances. I would personally use the amazon linux ami.
Use afnetworking to invoke a get or a post on the server app and you are off to the races.
take a look at this open source taxi project
its work with RESTful web services but its better to forget about Microsoft Windows its better to use Linux hosting for your web service.
New to iPhone dev here. Just wondering what's the best way to connect an iPhone app frontend (based on Cocoa touch ) to a php/MySql based backend?
The iPhone application will frequently access and change data stored on our server.
Read about mysql framework and MCPKit framework but these are for cocoa not for cocoa touch.
so can I access mysql based backend without any web service on server side.?
Many thanks
You can create a REST Api for your PHP/mySQL. Something like this

Then on the iOS side of things, you can use something like AFNetworking, to make requests to your server.

how to load the mysql server in android emulator
i.e
Class.forName("com.mysql.jdbc.Driver")
i got the exception java.land.ClassNotFoundException in com.mysql.jdbc.Drive
please reply me.
This assumes MySQL is publicly available from internet, but it is never good idea .
Setup public WebService and connect to it from mobile application.
You won't be able to run MySQL server on an Android device.
What you're doing, however, is trying to load the MySQL client library. That isn't included as part of Android so you cannot load it. You'd need to include the relevant JARs in your project, if you really do want to connect to a remote MySQL database from an Android app.
If you do want to store and access data on your Android device, the awesome SQLite database is included by default, including all the APIs you need to create, upgrade and otherwise interact with SQLite databases.
When I did this I created PHP files for the database operations. I sent data in XML and received data in XML all using PHP scripts. I found this to be the easiest way for me...but you need to know PHP of course.
