@mb: If you just want to play audio from a URL you can use [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; If you want to save the data locally use [NSData dataWithContentsOfURL:url]; to get the audio data, and then save it to a file with writeToFile. The method for saving to a database depends on the specifics of the database. But if you have an NSData object it shouldn’t bee too difficult.

@SHAYIN: There are many ways to do this depending on your requirements. Here are a few examples:

Create a web service on the Windows servers side. The app communicates with the web service to read/write data.
Export the data from the MS SQL database and import it into a SQLite database that you can store in the app bundle.

@Tyler: Keep track of the articles that the user saves. Store information about the articles (name, URL, etc) in a data file. The datafile can be created in many ways: a serialized NSArray object, a serialized array of your own objects, a plist, etc. When displaying the table view, read the data from the data file and show one table row per entry in the data file.

I have a blog app, and want to feature a save button where the user can save the article they are reading, and read it later. All of the HTMLs save fine in the documents directory, but I am unsure of how to get the tableview to show those htmls from the documents directory. any suggestions?

@Ayaz: Yes that is definitely possible. With local file names, spaces are typically not a problem.
For generic URLs you need to replace spaces in the URL in some situations. See the stringByAddingPercentEscapesUsingEncoding method in NSString.

@Adriana: Yes, the iPhone has very limited amount of memory compared to your browser on your desktop computer. It’s not very difficult to run out of memory by loading too much data into a web view. If you have control over the web page you’re trying to display you can try to remove stuff until it gets down to a reasonable size. If you don’t have control over the web page then you could try to load the HTML into a mutable string and then delete stuff from it before you load it into the web view. But this is dicey too since you may run out of memory when you’re loading data into the string, and you will probably have two instances of the data in memory as you load the HTML from the string into the web view.
