Can we have shared storage in iPhone which is accessible to other ios apps?
I am working on one ios app which downloads updated files from server. And there will be some other application which uses those files. So for that I want to save downloaded files on particular location. So that I can access those files from other application.
So the flow will be like this,
Application1, which will download files from server.
And
Application2 or Application3..... will use those files.
Do we have such type of shared location in iOS. Is it possible in iOS?
Thank you in advance.
No. Its not possible as your application will be in sandbox mode.
All applications are sandboxed as the other answers have said.
However, if you own both apps, or you know the developer of the other app, you could always use some sort of cloud storage, but that may defeat the point of you asking this question
You can't "share" files between in iOS, because all apps are sandboxed and can't access other files besides its own files with the public APIs.
Maybe you could combine the functionality of all the separate apps into a single app. Have each one be a module accessible from a master menu.

I noticed that there is software (such as iExplorer) that allows you to access files on an iPhone-device from your Mac.
Now my question is: How can I access iPhone files via Objective-c?
This is only for educational purposes.
I found this: https://github.com/Chronic-Dev/libirecovery but I'm not sure if I'm on the right track.
So it seems that you're looking for an API which makes it possible to access the filesystem of the iPhone from a computer. Well, this API exists, and it's called the MobileDevice framework.
Unfortunately, there's no easy or legal way to access files on your iPhone, especially through Objective-C.
The applications installed on iOS are sandboxed, which means they can only access files in their own directory tree; they have no access/knowledge of other files.
Like you said, you can access files using software like iExplorer, but not programmatically from the iPhone itself.
Here is an old project to browse the iphone. You may be able to get some pointers from it on building an application to do the same with the latest info.

Couple that with carbonic acid's post about the Mobile Device Framework and you should be able to do some good stuff.
if I find more unique info ill post it here.
I want to share my sqlite database between two iphone applications
In one application i am reading and writing into that database and in another
I am reading that data
Can we do this in iphone? And if yes How?
Appreciate any help...
Thanks,

iPhone Apps are sandboxed.. In simple terms If you create/Install a App, a folder will be created where all your files will be stored. In your case you will have your DB inside that folder.. Your app cannot access anything outside its folder. The same way Another App cannot access your Apps files..
So the answer for your question will be NO..
No. There is no way to access files outside your applications sandbox.
As everybody saying my answer is also NO..
but you can achieve the database sharing having a common database at the server and then syncing it on the both local applications.
I want to know if i can develop an app that would download books in epub format from a website and then it would be accessed by iBooks ( iPad app for Reading books ) to read that file.
The issue in my view is that an application can access files present in its own SandBox and it is not allowed to access any file outside it. Please explain if there is any way that files can be downloaded to a specific location on iPad which would be accessible by other apps.
Thanks!

No, apps generally cannot access files outside their sandbox (except Apple's own apps, of course, but it is very unlikely they would interfere in another app's sandbox).
However, that is why Apple introduced UIDocumentInteractionController.
Thanks Everyone i have found the answer!

We are looking on building a project that would run on Android, iPhone and other platforms with Phonegap. The app would be fairly simply, making use of the camera and basic UI features. The first versions would simply point to a web service and load information from there.
Over time, however, we want to improve the speed by:
1.) Downloading content via a separate thread when the app is running and storing the results in a local database,
2.) Hosting a mini webserver in the app*, and
3.) Pointing the PhoneGap UI to the app's mini webserver instead of the service's external webserver.
Two questions:
1.) Is it technically possible to host a mini webserver in iPhone that the app will access?
2.) Would this functionality be rejected by Apple?
Thanks in advance.
*I realize this step probably isn't really necessary. But, if it enables to truly build a "write-once-run-anywhere" UI, it might make sense still.
You're much more likely to want to have the HTML for presentation generated on your actual server, downloaded and stored by your separate thread as an .html file on the iPhone filesystem and served through local URLs using PhoneGap. Essentially, an advanced cache.
This way no web-server is necessary and you only need to write the UI generation code once on the server.
I would like to access the visual voicemail files that are stored on an iphone. Are there ways to access these files through the SDK? Does anybody have any experience in working with these files? I am assuming that they are files that are downloaded from the network and stored locally on the iphone.
No, each application on the iPhone is isolated, so you cannot access data for any other application, unless Apple specifically provides an API for doing so, like they did for the Contacts list.
No - the issue is that Apple provides very few methods to access data outside of your application's "sandbox". At this point, you can really only access contacts data and the camera via the supported methods. If you try to access data outside of your application without using an Apple provided public API designed for that purpose, your app will most likely not be allowed in the app store. Maybe this will change in the future, but I wouldn't hold my breath.
