I want to create an application in which i want a login logout authentication from the database file that can be handled by web services. This application should always need to be connected with the internet and after login i need to upload images and also give there views about the image and i am not getting any idea how start work on that can anyone help me.... I want to use this application some sort similar like facebook.
There is also a problem that which type of application i create native or web or else. Please help me to start this application.....
Try setting up a server that can handle the requests from your app. Your app can then request content or upload content to the server using NSURLRequest. For further reading refer http://developer.apple.com/library/ios/#documentation/Cocoa/Conceptual/URLLoadingSystem/Concepts/URLOverview.html
I think you are asking the wrong question. What web development language do you know to help you accomplish this? There are many different ways to go, like open source as opposed to paid, which services best handle your specific needs, like Ruby or PHP, which RDBMS to use, etc. If you don't know any programming, then it is going to be a long road. Your first step should be taking what you already know and branching from there, learning what you need to know. In your case, you'll need to learn server side scripting, connect it with a database, how to set up a server to put it all in, as well as client side development like javascript to go with the html.

I'm creating an iPhone Game where I want the user to get a unique numeric code when they first launch the app, that way when a friend of that user opens it, he/she can input that code and both users can get rewarded. I haven't encountered any issues regarding that, however what I want to do is make it to where the app registers the code given to every user and saves it to a website of some sort. That way when the other user enters the code, it will load the data from that website and check if it's registered. How would I manage to save the data onto a website? and also What free website could I use for this without having a character limit on the body page?
-Thanks in advance
Your thinking is correct, in that you need to save your data somewhere online, but you don't really "save data onto a website" in the way that you're describing. "Free Website" services usually serve a different purpose entirely - that of serving up public html pages. Sure, they can take the form of a CMS (like wordpress.com or tumblr accounts), but using that as an interface for storing your application's data is not something they're typically designed to do.
For something like this, where you have a public iPhone app that requires secure access to custom strings, you really want to have control over your own web server (different than a domain name, btw), and interface with a database on that server. This will come at a cost, and will involve more code than you're likely to find someone to write for you on here. Sorry to say it, but hey if someone wants to prove me wrong I'd love to see it.
Because all you need to store & retrieve are random strings (basically referral codes... if I'm understanding correctly), your database needs are pretty simple. If you're not familiar with things like PHP / MySQL, and you don't want to learn, it might be worth reaching out to some server-side developers for help. Unless there's more to it than you describe, you can probably find someone to help you for relatively cheap.
Good luck - and I'm sorry there isn't a simpler answer for ya.
You can send data using NSURLConnection. Just create an NSMutableURLRequest and call its -setHTTPMethod: method with “POST” as the HTTP method. Then, set its body and header fields appropriately, and you can use NSURLConnection to send the data.
I want the way with the fastest execution time. I'm not feeling comfortable of using web service because i need to create separate php pages and retrieve data as xml. If you think its good to use web service please tell me why. I want to code my database queries right on my c/objective c pages.
I've been searching for libraries. I saw this sequel pro - won't i have any problems on using this - like licensing issues? I also saw this libmysqlclient of cocoa but some say its not working well. I've also read about a library developed by Karl Kraft found here http://www.karlkraft.com/index.php/2010/06/02/mysql-and-objective-c/ but don't know if i could trust this.
I would really appreciate you help.
Definitely build a web service to act as an abstraction layer to your database. Here are some significant reasons in my opinion:
Since you want speed, you will be able to add caching when using the webservice, so you will essentially eliminate the need for identical queries to run (sometimes).
If you need to change your data model later, you just have to modify the webservice backend and don't have to update your app.
You can better control security by not exposing the database to the world, and keep it safe behind the web service.
Your database credentials should not be stored in an app. What if you needed to change those?
I strongly suggest a web service. Hope this helps.
Connect to your DB by PHP and output the result as JSON
is much better and faster then xml and less coding if use JSON Framework.
and never never try to connect to your DB from your iphone because it easy to sniff out the request from iphone.
Being safe then Sorry, keep that in mind
i am trying to create an app that connects to a mysql database, downloads the records in the table for the user then displays them in a UITableview which can be drilled down with the data that as downloaded from the mysql database. I would also like the data to be stored locally in something like sqlite. The data would then be modified then uploaded back to the mysql database.
My questions is where do i start? I have read alot of posts on google and they say that its best to connect to a xml which acts as a middle man between the database and the app. How can i create this xml file? is it something that is generated every time the app is launched or something done daily on the server?
If anyone can help me out. i know its a very broad question so if someone can point me in the right direction im not asking someone to right this app just a hand as im lost.
Thanks,
Aaron
I know others have mentioned links to libraries that let you connect to MySQL from iOS. I've not tried them myself but don't rule that out.
To answer your quest, you do not "create" the XML files. Web services are developed in a language, and written as applications. You would in essence need to write another application that runs on a server. That application would connect to your MySQL database. That application would also publish methods for getting at, and updating, data. By virtue of making your server a SOAP web service (in whatever platform), the data will be sent over the wire as XML.
If I have understood you want a kind of ORM?
If so you can check for Restkit and more specifically on the side of the object mapping system. It allows us to synchronize remote object/data locally with the coredata.
I have never used it, but I have seen a great tuto which talking about that here: Advanced RestKit Development (However I think it works only with json messages).
I hope it'll help you in your reflection.
I would recommend looking at XML Parser, Webservice, and Core Data tutorials.
SOAP and XML Response Parsing Samples for iPhone/iPad?
http://www.techotopia.com/index.php/An_iOS_4_iPhone_Core_Data_Tutorial_%28Xcode_4%29
That would be a good start, and I could give you some more material if you would like. As far as setting up your actual web service, I've never done that so I couldn't help you there.
Im new to website development and design so apologize in advance if the question is redundant.
I have a program where a client, using a URL string fetches a XML file from a webserver. This would be no problem right if it were a simple URL with no security or no CMS (like Joomla) involved: Just put the exact URL string and the client gets the file from the web server, done.
But, how would the process work if the URL is on my site hosted on GoDaddy and using a Joomla CMS?
Im trying to understand how the same process of fetching a file works on a hosted server using a CMS. Since I just made the transition from my site being on my school's servers to having a Joomla website Im hosting on goDaddy.
I mean where would I put the file if I also want the file to be accessible only if the client authenticates itself first. Just to be on the safe side. I mean is this how normally things work in mobile apps? I have a client program thats a iPhone app and within the app I have a XML file which is used as a data source for my UITavleView, but I want to check some URL to see if an updated version of the XML file exists. My app side programming is mostly done, now Im trying to learn the server side things I need to do to make this process happen with Joomla and my own hosted site
I donot understand how would the process work in that case. I mean, what are the things I would need to do on the server side to and the client side to make this possible?
Please help me understand or if you could point me to some links where these steps are illustrated...or if you could give me some Google key words I can search for to learn about this process.
thanks a lot
The fact that you have a CMS does not generally change how you access a file within the file structure of your domain unless the CMS protects certain directories. In this case, Joomla does not so you can directly access any file you wish. Depending on the sensitivity of the information you are trying to retrieve, you can protect the directory through your domain management panel. If it's not particularly sensitive, the authentication can be done by the app since the URL you are accessing can be easily hidden from the user.
It seems like that would be the simplest solution since the app will have access to user information by nature of where it resides.
I'm in the middle of working on my first native application with networking and I have a question regarding the best way for interacting with remote storage. In a perfect world I'd like to do the following.
Prompt the user for login information from the iPhone.
Verify the users credentials and connect to a MYSQL database hosted by myself.
Parse MYSQL data into a table view.
Allow the user to add or update information in the database.
I've read some similar questions posted, maybe something's lost in translation, but the two most common means I've come across are.
Create a web service for handling these requests using SOAP/REST/JSON (no experience doing this, but would like to learn if it's a better implementation)
Write PHP scripts (enough experience to get by) that will grab data username/password/requests securely from my NSURLRequest and echo the NSData as XML and parse it with an NSXMLParser.
Are there other options? Is one a better implementation over the other? (web services come up more in searches)
Thank you in advance for taking the time to read my question and possibly clearing up any confusion.
Whoa! Web Services! Oh wait, calling a PHP script that returns JSON is actually also a web service. Well, that makes things simpler :-)
Yeah, so I would go for this:
Write a PHP script that returns JSON data (many tutorials available)
Protect the PHP script by setting up 'Basic access authentication' (Apache documentation)
Tell Apache to take the user database from your mysql database
Run your service on secure (HTTPS) web server (important because basic auth is not secure)
This way you can use almost all standard components on the iPhone side. NSURLConnection will talk HTTP(S) and there are excellent open source JSON parsers for Objective-C.
