There is a section of the NSString documentation:
Creating and Initializing a String from an URL

There are many options for you to choose from to get an NSString containing the contents of a webpage given its URL.

I provided you with what I think are the best methods for achieving your goal. Did you try them and they were insufficient for your purposes? If so, what did happen and what were you hoping for?

So I gave you information on how to get the contents stored at a particular URL into a string. You want those contents stored in a file. What would the next step be?
http://developer.apple.com/library/...String/writeToFile:atomically:encoding:error:

If I was doing this particular task, I'd be writing a shell script that used wget or curl depending on availability, but if you're going "heavy-weight" and using Objective-C, I'd use the NSString methods above because they're what I know. There may well be a single method elsewhere that will do this in one step.

is there anyone who can show me an example how to download a webpage into a folder using NSURLConnection?

Why use NSURLConnection and not NSURLDownload?

NSURLDownload provides an application the ability to download the contents of a URL directly to disk. It provides an interface similar to NSURLConnection, adding an additional method for specifying the destination of the file.

Isn't that what you want?


The NSURLDownload chapter of the URL Loading System Programming Guide that chown33 kindly pointered you towards has lots of examples of using NSURLDownload with lots of detailed explanation.

1) you didn't say iOS, which meant everyone thought you were using OS X, because:
2) you're posting in the wrong forum. Go to the iOS programming forum for iOS-specific questions.

Acting exasperated that we don't know a detail of your question you didn't mention serves only to frustrate those that might help you here and on the iOS forum. Be specific with your questions, it will benefit everyone.

Did you try searching?
Google search terms: download a webpage using NSURLConnection

Did you try reading the class reference doc for NSURLConnection, and looking at the linked sample code.

Did you try anything other than asking someone to give you the answer?
What have you tried?
Click to expand...

yes i searched, but there was no sample for that! were you able to find one?
yes i tried, for NSURLDownload there is a clear and helpful documentation that exactly helps you for this matter, but for NSURLConection its not that easy to find how it works!
