iOS Receiving Data From a Server - ios

I am interested in making an app that reads "text" from a file and prints it into a label.
I would receive the data from a server and the label will print that text.
Does anyone have basic websites, documents I should take a look at?
I need to get a starting point. NOT interested in any code for I am doing this as a learning experience. Do you know of a good place to start?
Thanks!

Start by taking a look at NSURLConnection. You can find a basic outline (and code) here. There are lots of examples around this if you Google it.

App that will pull data from website flash game

Basically I need information on how to pull data from a flash game webbased client and put that data into an app. The game is evony.com its a webbased flash game. I can probably figure out the coding such as parse the login and password and display the information in the app. What Im have major problems is following,
How can I find out what data in what format is being transmitted from
webbased client to their server.
What software, preferably free, is out there that will do this for me?
Is there any tutorials, explanations, pointers anything describing this
on the inet because I have searched high and low without success.
I think the problem is because I am a beginner, I do not know the correct wording to serch for to find this information. It's a little like a needle in a haystack :) If you know what you want but dont know what it is called, get a new hobby :(
VERY much appreciated for any help, pointers, explanations, descriptions, tutorials or anything that can help me with this, very very much appreciated all.

The tool of choice to get started is WireShark. Its a software to monitor in- and outgoing datatransfer. It's very powerfull and a bit complex to get filtering right. Try something different to get started (e.g. do a ftp-login and try to "steal" your own password).
In Step two, you need to reverse engineer the communication between your client and the server. Thats the fun part. If it is encrypted, bad luck.
If you want to read the data, you can use libraries like LibCap to get the data in a language of choice. The flash player interacts with the game and you read the data transmitted.
If you are going for a stand alone program without the running flash client, you need to write your own client based on the protocol you got from step two. Be prepared to be kicked and banned permanently on the slightest error. I haven't checked on this one but every MMO I know and I can imagine do prohobit such tools.

Use both GPS and Scan function in same channel with Junaio AR

As the title says, im simply wondering if it is possible to use the GPS tracking and POI part of junaio, and att the same time use the scan functionality to scan and recognize images. Im working with a group at a project which demands that we use both functionalities, and we are at the moment stuck on trying to send 2 XML documents, causing the server to return nothing at all. I simply want to know if it is possible to use both functionalities in the same channel, and I would greatly appriciate if someone would point me in a direction which could help me solve our problems, since I've been able to find absolutley nothing on my own. Thanks beforehand!
Scan + GPS/compass is not possible at the moment.
However, it's possible to use GPS/compass tracking and continuous visual search at the same time. This might be the closest thing to your requirements.

how to check data usage

Hi take days looking information about this and I have found absolutely nothing, is there app like Onavo using a proxy, but some do not and I need to know how much data I'm consuming at one point to see if it is producing for such a shock, I need a lot of help if they have some information please help. for example:

EverNote OCR feature?

I downloaded the EverNote API Xcode Project but I have a question regarding the OCR feature. With their OCR service, can I take a picture and show the extracted text in a UILabel or does it not work like that?
Or is the text that is extracted not shown to me but only is for the search function of photos?
Has anyone ever had any experience with this or any ideas?
Thanks!
Yes, but it looks like it's going to be a bit of work.
When you get an EDAMResource that corresponds to an image, it has a property called recognition that returns an EDAMData object that contains the XML that defines the recognition info. For example, I attached this image to a note:
I inspected the recognition info that was attached to the corresponding EDAMResource object, and found this:
the xml i found on pastie.org, because it's too big to fit in an answer
As you can see, there's a LOT of information here. The XML is defined in the API documentation, so this would be where you parse the XML and extract the relevant information yourself. Fortunately, the structure of the XML is quite simple (you could write a parser in a few minutes). The hard part will be to figure out what parts you want to use.
It doesn't really work like that. Evernote doesn't really do "OCR" in the pure sense of turning document images into coherent paragraphs of text.
Evernote's recognition XML (which you can retrieve after via the technique that #DaveDeLong shows above) is most useful as an index to search against; the service will provide you sets of rectangles and sets of possible words/text fragments with probability scores attached. This makes a great basis for matching search terms, but a terrible one for constructing a single string that represents the document.
(I know this answer is like 4 years late, but Dave's excellent description doesn't really address this philosophical distinction that you'll run up against if you try to actually do what you were suggesting in the question.)

Ambitious Networking Project for iOS, need direction

I'm challenging myself to write an app I know nothing about in 2 months time and I need some direction. Suppose you wanted to create an awesome iPad app that takes craigslist posts and displays them in a neat fashion. How would I gather the information from craigslist.org using Objective-C/C in xCode? What objects would I be interacting with to create network connections and how would that information be read in? Would I be reading the source code?
Thank you!
Craigslist has RSS feeds, so I suppose you could just get the link, parse the feed, and display it on a table. There are too many examples to count out there on how to do that.
