I have an app that saves data in my Documents directory. It would be very useful to be able to mail the data file to some other users so they can also use the gathered information. I have spent most of today looking for a solution, but have not found any answers basic enough to be of any help. So, I would greatly appreciate some help to get me started. Like, what do I need to do to make IOS aware that I am interested in opening ( in my case actually only copying the file to the app’s Documents directory for further chewing) a file with, for example the .xyz-extension and how this is done.
Much appreciated,

Running on a real device, there seems to be no problem.
I am trying to learn iPhone App Development using MonoDevelop and C#. I have created a sqlite database file userinfodb_v1.sqlite and placed it in a subfolder called Data in my project. Now I am trying to write the connection for the application to fetch data from the tables. I haven't got much clue as to how I should form the connection string as I have only about started. This is what I am doing:
string strconn=Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), "Data");
scon=new SqliteConnection(strconn);
scon.Open();
However this is not working as the connection is failing. What should I do to establish a connection? Where is the error in my code? Can you help me correct it? Any help will be massively appreciated. What does Environment.SpecialFolder mean? Where should I keep the database file in order to access it properly?
Many Thanks in anticipation.
When your application starts you need to copy the database file from the bundle to the Personal folder.
I’ve looked through the posts on the Cloudmade site here and I get some of it, but not all. I've posted the question below, but haven't had the help I need, so I thought I'd ask the question here.
I can see that I need to:
download the tiles for the required area to my Mac (but can’t see how to do this)
convert these to a sqlite database using the map2sqlite utility, changing the code to output the tiles to a table called “ZCACHE”, not “tiles”
Copy the DB to the Application Bundle
insert some code to copy this DB on first run, from the Application Bundle to the Documents Directory
Somehow get App to use this DB and not an online one – I can’t see how that’s done.
Any help would be warmly welcomed,
Chris.
The best solution for me to have iPhone offline maps is:
1.- Generate your own maps with TileMill and then export to MBTiles format.
2.- Get the mbtiles-ios-example and use the MBTiles file you just generated. In order to compile it, you need to download Route-Me and add it to the project.
Now, there is another option (not for free): Mapbox.
please check this tutorial, it can help - http://www.gisnotes.com/wordpress/category/sqlite3/.
I just want a tutorial demonstrating the parsing of XML File using libXml2 in Iphone . I found tutorials on TouchXMLand other but not the same for Libxml2
Please help if u can.
Apple has an example iPhone project that parses some simple XML using both NSXMLParser and libxml2 SAX2. You can find the project here:
http://developer.apple.com/iphone/library/samplecode/XMLPerformance/Introduction/Intro.html
Although this isn't exactly a tutorial, it is working code. It runs in the simulator out of the box. Because it accomplishes the same task twice, you should be able to compare the libxml2 code to the NSXMLParser code to figure out what's going on.
Not even these?
I recommend TBXML. I use it everytime I need to parse a XML File. It's really easy to use. ;-)
See here: TBXML Homepage
A good sample is:

I'm writing an iPhone app which downloads a tar-gzipped file from a Webserver, then needs to unarchive this file so that it can be copied into the app's Documents folder.
I'm using tar/gzip because I want to download a whole bunch of small files in one HTTP request, to make everything nice and fast.
I've investigated solutions like http://www.feep.net/libtar/, but as a C/Objective-C newb, I can't get any of them to compile for the iPhone platform.
(I felt like I should just be able to do a system call to "tar -zxvf myfile.tar.gz", but it would appear it's not that easy!)
So is there a simple way to just un-tar a file on the iPhone? Or am I going about this all wrong, and is there a better way to do this?
Thanks in advance!

This blog post should help you:

EDIT: Google cache version of the same page which actually links to a forum post here which links to a Google Code project here, containing some code which implements unzipping on iOS.
Here is a light untar library for iOS : https://github.com/mhausherr/Light-Untar-for-iOS

Hope this helps,

I took a different approach by building libarchive and bz2lib as a static library for iOS. You can find it here:
