I have a website, let's say it's "http://www.jwilkthings.com/stuff"
I have a bunch of .txt files stored on this website, i.e. "http://www.jwilkthings.com/stuff/text1.txt"
What I'm wanting to do is find a way in iOS to download all of those text files without knowing what the document name is. I can already retrieve them manually as long as I have a file name, but I would rather just get all of them at once and put them in the documents directory if possible. I currently use FileZilla to upload all of the text files, so I can use FTP if needed.
The correct way to solve this problem is to not use FTP (riddled with performance and security issues), and to configure your web server to expose a table of contents directory listing that your client can parse.
But that's not an answer to your question.
If you really want your iOS app to speak FTP, take a look at the SimpleFTP sample project from Apple.
It's old, but I just got it to build on iOS 5. The ListController.m file has the code you're looking for.

In order to be able to access iCloud Drive from the application,
I think that we want to use UIDocumentPickerViewController from the application.
but i found following problems when i use UIDocumentPickerViewController.
Cannot upload multiple files at once.
Cannot Download multiple files at once.
When pushViewController from navigationController then display
become strange.
I want to avoid above problems, So is there any another way to get files information from iCloudDrive without using UIDocumentPickerViewController?
like Send some request or query.
I have searched lot and didn't find any query or request to get Files ,Upload files and download files from iCloudDrive.
if you have any idea about this please tell me.
Thanks,
I don't think there's any straightforward alternative, but you could think of...
...using iCloud directly (not iCloud Drive), but then users will only have access to their files from your application
...using Google Drive's sharing extension which supports uploading multiple files at once (the Dropbox SDK probably supports that, too, but their sharing extension doesn't)
...zipping all files before uploading them
...changing the file format so that it's a bundle of multiple files, if you are in control of the file format
...file a radar/feature request, and possibly wait forever ;)
Not sure if that helps, but I don't think you have much of a choice here.
I am developing an iOS app that uses a large amount of images that are needed for animations for short videos. I want to save my application assets as static files in cloud and once they are needed download them using secure API call (either JSON, XML or any other alternative for that matter).
What is the best option for that. I have checked Parse, Dropbox, iCloud, Google Drive, but I am puzzled since I see only instructions for dynamic data that lets users access content they have created and not static assets.
What would be best option for that?
If you just want an easy way to serve static files I would take a look at Amazon S3. You can just upload files through the online console and then get the public URL to those files to use in your app. You can also use the S3 API to upload files through your web service or iOS app.
Hope this helps!
I'd go for Parse (basically because it is fast to learn and develop), you can create a table with the images and change the writing permissions if you are afraid somebody could modify the table.
Another option that you can check it's the special Config table so you can upload custom files (zip files i.e.) and download them in demand.
I am working on an App, in which I want to upload images and pdf to the FTP server. I am using this reference ref.All is working good. The images and pdf are getting uploaded on the server with proper names and sizes.
But, now I want to check if the directory is already exists on the server or not. I am not able to get it to work with this library.
So my question is that how to check directory on ftp,if directory is there then upload the files if not then first create directory on ftp and then upload files onto that directory?
Any Ideas.. ? Any help will be appreciated.
Different FTP servers will answer the LIST request in differing ways, so there is no single answer to this question. RFC959 says on the matter:
Since the information on a file may vary widely from system
to system, this information may be hard to use automatically
in a program, but may be quite useful to a human user.
Using the CWD request to change into the directory in question, and detecting a successful response will detect the directory, however that leaves you in that directory as a potentially unrequired side effect.
For these reasons, as well as others, you may find more modern protocols such as SSH (which includes a file transfer feature) to be more useful. You may find the DLSFTPClient CocoaPod useful.

I have a custom requirement in one of my products and I need to protect or encrypt files that are stored inside the NSDocumentsDirectory folder. Even if these documents are mailed (The app has the ability to mail documents) to some other person , he or she will not be able to open this document without using my app (I will be using open in functionality of email attachments). So basically only the application can access all these documents and without the app the documents should be mere junk. IS there any way to do it, or has any one done something before.
I also saw this but could not get a complete idea.
If you want a quick and easy method for data that doesn't need serious security, just zip the files with a fixed password.
ZipArchive is a good library for this.
For a more serious approach, check iOS - Protecting files with a custom encryption key?
The other post you mentioned works on the concept of password protecting the files, I had encountered the same issue that was for my custom defined files in which our team, encoded the contents of the file on random locations, and saved it.
Only our Application could decode it correctly as we had the key :)
It was a windows application, It would work here also.
I need to upload multiple files on my website.
But I need not just a form for uploading multiple files, I need to upload whole directories.
How's this possible for the minimalist?
Yours, Joern.
According to my somewhat limited knowledge this is not possible, only file transfer is possible, not directories.
Here are some workarounds, based on discussion on Velocity Reviews and another discussion:
upload a zip, which you unzip at the server side
upload directories over ftp (web page can be a front end to this)
upload files one by one
I would go either for zip or ftp. Note: someone might have produced a gem that enables uploading directories (I know nothing of such thing, but I will be happy to find out, if there is).
Adding another option to the list provided by Sorrow:
upload via REST/JSON
OK, this is a partial solution, but it does give you the opportunity to write a script that reads your directory and POSTS to your website.
