I am building an app with several podcasts. Each podcast gives the option to download the MP3 to the app. I have about 6 podcasts and would like to Tag each, so that when the archive view is clicked from each podcast, only archived files from that particular podcast show.
Is there someway that I can add a Tag or something to the downloaded mp3, and then in the archive, search only for mp3s with a tag related to that podcast?
BTW, I am using NSURLConnection to download each file
I think you may be looking at this in the wrong way.
Rather than tagging your downloaded files, you could set up a data structure to hold information about your files and use that to display your information.
For example. If I were doing this I would have a Core Data model that held information about the downloaded file, and tags, or sources, and I would store the path to that file in the database. That way, you can store whatever information you like about the downloaded file, and you can access it through it's path.

I use the extension News System to manage my newsitems and I need to add mp3 file to my records using [fal_media]. But in the list of allowed file extensions I don't have MP3.
And even if I downloaded an audio file (mp3), it disappears when I save the content.
I checked the [SYS][mediafile_ext] on the Install tool and I see that the MP3 extension is already there.
Why I can't see MP3 on the Allowed file extensions?
As you have checked the system configuration which enables mp3 files, something has restricted the use of mp3 afterwards (as Robert mentioned)
In general EXT:news (7.3.1) does not modify the available fileextensions (3rd and 4th paramter of getFileFieldTCAConfig() calls in Configuration/TCA/tx_news_domain_model_news.php for the fal_mediafield is empty) something else has modified the list.
You may check if mp3 is removed everywhere, checking the TCA for all tables (there should be some mentions for tt_content)
Then you might check the site extension or page_TSconfig for the origin of the removal.
Here is a situation I have a data file in document directory which is being updated in the application every now and then. So I want to save it to my desktop using iTunes. But I don't want that the file should be uploaded back to my application. i.e. I want that user can download the file but can not upload any.
I was thinking to have the data file on some other location like Library and put a button on application settings saying "Prepare backup" that will copy that data file in Document directory, from where user can download it. If user uploads any thing it won't make any difference as my current file is in Library directory.
This is just a thought,
can anyone suggest me other way or the above way is good to go?
Edit: I just need that after the successful export user can view the data file (may be later) without support of the application.
You can't.
But what you can do is check (using an timer every 10 seconds) if a new file is added to the documents directory and then delete it programmatically.
But this ofcourse doesn't disable the replacement of files.
I have an app I'm designing that will allow for lots of PDF viewing. There are a lot of different languages available, and so if I were to include all of them in the app, it would be like 100+ mb in size which just won't fly.
So I'm thinking that I am going to put the pdf's on my server, and access them with a direct download link like this:
http://mysite.com/pdfs/thepdf.pdf
Which will return the exact pdf I want. So I'm wondering how I can go about accessing these resources as I download them on the fly?
I imagine I need to save the pdf's to the app resources folder? And then when a tableView row for the pdf is selected, I check if the pdf is in the resources folder (how do I do that?), and if not, pull it down off the server, and load it into my view?
I think I have an okay idea of what I need to do, just not very clear on the code to do it. Can anybody post the code for accessing the resources folder (if that's actually what I need to be doing), and maybe the code for how to check if something is in the resources folder?
Thanks!
Have you considered using a UIWebView to view the PDF instead of downloading and loading it yourself? UIWebView should take care of caching, so you won't have to worry about that.
Assuming that a UIWebView won't work, to download PDFs and see if they exist, you need to store it in the Documents folder. The resources folder cannot be altered after you submit your app to Apple, but the Documents folder in your app is completely fine. To access it, I would actually recommend ConciseKit, which can be found on GitHub. It gives you a helper method to access your app's document directory. The helper method is
[$ documentPath];
Then you can get the path for a file by doing
[[$ documentPath] stringByAppendingPathComponent:#"file.pdf"];
So that is how you get a path to a file, to check if it exists, you want to use NSFileManager.
[[NSFileManager defaultManager] fileExistsAtPath:#"path from above"];
I'm working on a iphone application project in which, i have around 500(250mb) audio files.
When i got them from studio they were in wav format, I converted them to caf(35mb).
is there any other way/format i can compress them ?
dumping 500 audio files to iphone app resource will be good?
any suggestions?
In Storm Sim I did a folder reference for the audio samples with the files structured inside subfolders so I could keep them organized in a somewhat sane way.
Instead of using the standard get resource calls I just ask for the app's main bundle directory and the referenced folder is inside the main app folder with the appropriate subfolders under it.
Let me know if you need a code sample.
We have very huge music files in mp3 formats (very huge more than 1,000,000) and would like to import all these songs into the DB of an application we are developing. Is there any easy method to import such huge files at once. Kindly let me know
Why not just use a filesystem for them - that's what file systems are designed for? Index the filenames in a normalised DB.
Yes, there is
Take a look at how has Apple solved that problem. Go to the iTunes_control folder on the iPod. You'll see that there's a Music sub folder with dozens of folders named f00, f01, ... f50 (50 is arbitrarily big number). Every file has been renamed to a filename that looks like a hash value.
Use the file system to store the files. In the database store the path to the file on the file system together with the mp3 metadata information (artist, name, album, composer, etc) and provide search capabilities over it.
You don't want to store music into the database. Store some kind of URLs to music into the database, with all the metadata you want to keep, and store music into folders on various servers. I am author of radio automation software that used this scheme and we never looked back at our decision.
Main reason for that is that you don't want anyone to be dependent on some database API to extract the music.
