Access data uploaded to public folder-Google Drive Objective-c

I am trying to upload pdf files on Google drive or any cloud service and read these files in my application, do I have to use SDK's or there is a way to get files from public folder without forcing the user to login?

Is there a way to create a Dropbox link that opens a file or a folder in the native app?

Basically, what I would like to do is to create a link from a web application that will open a Dropbox file from appropriate Dropbox native app. Google Drive for example allows you to re-format the unique URL for a file such as https://docs.google.com/blablabla which you can retrieve from their API, into googledrive://docs.google.com/blablabla and lets you open the file in Google Drive native app.
I have tried dropbox:// URLs with no success, and have not found any existing conversation on this despite running cross multiple conversations on the same subject for Google Drive or Evernote. Please let me know if it is possible to somehow generate this via API or based on the folder structure etc.
Thanks!

Using dropbox Chooser drop-in to retrieve a non-expiring link to files

I would like to use the Chooser drop-in to select a file from dropbox and then synchronize my app with that file occasionally in the background.
https://www.dropbox.com/developers/dropins/chooser/js
A scenario would be:
List item
User selects file.
File uploads to my app.
User returns to my app a few days later after modifying the file in dropbox.
My app should synchronize and pull down that particular file (without again displaying the Chooser drop-in).
The problem is that the Chooser provides an expiring link to the file:
"direct" is an expiring link to download the contents of the file
I can use the Core API exclusively which would work, however I would have to build my own UI to browse the user's dropbox directory. Ideally, I'd prefer to not introduce the world to another file browser; Dropbox has a file browser - and people are familiar with it. Is this possible?
Thanks,
You can just get a preview link and convert it. See https://www.dropbox.com/developers/blog/53/programmatically-download-content-from-share-links.

OSX iCloud share files between apps

Is it possible to share files between different applications though iCloud? For example may I export epub book from my app to make it appear in iBooks or export a document to Pages from my application? And is there any way to get this files or pictures from photo stream in my application?
You won't be able to write files to another's application sandbox, precisely because the Sandbox won't let you write outside your app's container. What you can do is invoke a save panel to let the user export the file as an ebook wherever he wants. He can then open the file in Pages and move it to the cloud there.
And no, there is no API to access your Photo Stream.

How to attach a file from ipad in your application?

I have developed an application in ipad, i want to browse a file from ipad and attach it to my apps..it should not be like e-mail attachment..am sorting out the code but am gettin code for only email attachment
The only files on the iPad your app will be allowed to browse are the files inside your app's sandbox or those accessed using a framework like the Assets Library Framework. As for "attaching a file to your apps", what do you mean by that? Can you clarify?
