How to upload file from my iphone application to user own dropbox? - objective-c

I had created an iphone application witch can generate a pdf file when the user use the application.
how can the user have the option to sent the pdf file to his own dropbox?
I had tryed with dropbox examples: where i can make an api and upload to my own dropbox.
But it's not what i want.
I want my application to do so: when the user generates a pdf file, so the login box of dropbox apear so he can log in and upload the file automaticaly to his own dropbox.
I have google it, but i did't get any examples including this solution.

upload files to any user's google drive after they authenticate

I want to upload files from my server to my users's google drive storage, after they authenticate, the questions are:
Is it possible to do that?
Do I have to re-authenticate the user every time they like to upload a new file?
Could I embed the uploaded MP4 files in my website? (using the html video source as the file's download link of the user's google drive account)
do I need to re-authenticate the user if they just want to see the embedded videos some time later, in other words, is there anyway I could save some sort of a Token so they don't keep doing that.
Is it possible to do that?
Yes
Do I have to re-authenticate the user every time they like to upload a new file?
No, store a refresh token for the user and they wont need to authenticate each time.
Could I embed the uploaded MP4 files in my website? (using the html video source as the file's download link of the user's google drive account)
I wouldn't recommend it google drive isn't really designed for hosting of files in this manner that and people would need access to the file to download it anyway, its a big can of worms.
do I need to re-authenticate the user if they just want to see the embedded videos some time later, in other words, is there anyway I could save some sort of a Token so they don't keep doing that.
Yes as mentioned if the files are uploaded to your drive account you own them. You would need to share the files with anyone that you want to have access to them. You could set the files to public but thats not the best way to go about this.

The kind of Dropbox link you're referring to isn't a "direct" link, but rather a "shared" link, where the link itself points to an HTML preview page, where the user can download the file if they want. You can find information on this feature here:
https://help.dropbox.com/files-folders/view-only-access
Dropbox does offer an API you can use for listing, uploading, downloading, and sharing files, among other operations. You can find everything you need to get started with the Dropbox API, including documentation, tutorials, and SDKs here:
https://www.dropbox.com/developers
Dropbox does offer a .NET SDK in particular:
https://github.com/dropbox/dropbox-sdk-dotnet
To create a shared link for a file or folder using the .NET SDK, you would use the CreateSharedLinkWithSettingsAsync method:

Can I upload files from a custom website form to Dropbox?

I have clients uploading files directly to my Dropbox folder. I was curious if I can build a website form that uploads the file to my Dropbox folder and also saves the forms data to my server with a reference to the file that was uploaded to Dropbox? They are legal documents and I don't want to worry about security if Dropbox handles that.
It looks like it should definitely be possible.
You would have to use the dropbox api:
https://www.dropbox.com/developers
https://github.com/dropbox/dropbox-js
There are some javascript examples that would likely be what you would need to go directly to dropbox without going to your server first.

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.
