picking a file from the memory of iphone? - iphone

i am making a client server program for iphone communication with the sever i want to know
that how can i pick a file (jpg, 3gp, bmp or some word document ) from the memory of the
iphone and send it to the server please explain in some detail as i m new in iphone
programming and give some code for it if possible, and how can i convertv an adobe reader and
msword compatible file to jpg file.

Slow down there buster.
There is no "memory of the iPhone." You'll have to get that file in somehow besides a traditional file system. There are ways to send files to other apps… check the docs. To start with, why don't you bundle in a couple files with your .app to test with.
Once you have the file, use something like the ASIHTTPRequest library (google it) to send it to the server.
Clear?

Read iPad/iPhone Disk like USB Flash Drive

I need to get some direction on how to read the contents of an iPhone/iPad device like it's a usb flash drive. I have downloaded iExplorer and phone disk from macroplant, which do exactly what I need, but I need this functionality integrated in my app.
Not looking for a full solution (won't reject it either :)), but I need somewhere to start.
Any ideas?
I know that there is manzana open source library (C#) that lets you read/write files from/to the iPhone, list directory contents and other file and directory related functions.
I saw links on google code but wasn't able to downloaded sources. May be you will find.
Good luck!

getting data from server and store in the iPhone

i want to develop an iPhone app where the app downloads data (say audio clips) from a specified server and stores it locally on the device.
then the app should use the data stored in the device rather than stream it from the server.
could anybody give me the guidelines as to how this can be done? tutorials and samples also appreciated. Thanks :)
The easiest way to play files from the internet is to use -[AVAudioPlayer initWithContentsOfURL:error:]. If you want to make sure that the whole file is downloaded, I think your best bet would be to download the file using NSURLConnection (see the URL Loading Guide) and then using -[AVAudioPlayer initWithData:error:].
Look into ASIHTTPRequest, you will find it much easier to fetch large chunks of binary over the web asynchronously than if you try to code everything yourself.

iphone: coding a data compression or zipping agent?

I'm creating a simple service for uploading photographs from an iphone to a web server.
However, before the requests is sent, I want the app to compress the pictures (custom format or otherwise) in the background before sending it.
Any pointers on how I could go about doing this?
Check out the NSDataCategory posted to CocoaDev. It does exactly what you're looking to do.

I use ziparchive to unzip content downloaded from a server. It also has functionality to create zip files on an iOS device and might be what you are looking for.

Reading iTunesMovies file in iPhone?

In iPhone, the iPod app saves the media files (audio, video) with strange names and in weird folders (F00,F01 etc). There is a file named iTunesMovies in iPhone, which contains all the information about the metadata of those video files and how they are to be displayed in iPod app. I copied that to my Mac also, and when i tried to open that file in textEdit, it showed some alien characters which made me believe that it is encrypted may be(Thats just a wild guess).
I want to read/change the contents of that iTunesMovies file. Can i do that? Is there any Framework which deals with that iTunesMovies file?
Thanks in advance
I don't think there's a framework to do this, but you can probably do it yourself by reading the file into an NSData object, then manipulating how you would like. Your app will have to be running outside the sandbox, as well. Something I don't know how to do.
Keep in mind that this isn't allowed by Apple, so any apps you make that use this would have be distributed through other means.

How do i stream an audio file from the server to iphone?

I need to stream an audio file which is saved on my server. Is it possible for me to stream that file in order to play it on my iPhone? Or is there any other way to play an audio file from the server to iPhone? help me please.
Thanks,
Shibin
This link was useful to me : http://cocoawithlove.com/2008/09/streaming-and-playing-live-mp3-stream.html
He's got a project linked from that page http://projectswithlove.com/projects/iPhoneStreamingPlayer.zip
In this project, interesting lines are in iPhoneStreamingPlayerViewController.m, lines 82-89 start streaming the audio from a url.
I've manged to get this running on my iPhone and tested it using an mp3 on another server and it works fine. However, I've not picked through the code so I can't help you anymore than this, sorry!

NS To get the project to compile I had to change the SDK to 3.0 - if you right click on the project name and choose Get Info, then change the option called Base SDK to iPhone Device 3.0 and it should work.
There's a couple of ways to get the file playing on the iPhone, but the first problem is that you need to decide how to serve the file from your server.
One great way is to share the file out via HTTP using a Web Server. If the server is Windows, look into 'IIS'. If it's a Mac or Linux, Apache is your friend.
Once you've got the serving going, here are the options on the iPhone:
1) Use iPhone Safari to navigate to http://your-server/your-folder/the-file.ext. If the serving is correct, it'll open the mediaplayer and stream it.
2) Write an iPhone application that uses the AVMediaPlayer framework to play the file. Non-trivial, but there are plenty of samples.
