I'm using the NSURLConnection class to download a large file in my iPhone application, but it crashes every so often because it's using too much memory. I'm doing the usual NSURLConnection usage, to append the received data to a NSMutableData object.
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {

Hello All,
I am writing an iPhone app which connects to a stream and parse bytes from it then create objects.
For exemple, first 11 bytes are the header, next 246 bytes are body..., I am thinking about creating class representing them, like FrameHeader, FrameBody, the question I have is what is the best way to consume data without copy...

With all the URL-handling objects lying around in the standard Cocoa libraries (NSURL, NSMutableURL, NSMutableURLRequest, etc), I know I must be overlooking an easy way to programmatically compose a GET request.
Currently I'm manually appending "?" followed by name value pairs joined by "&", but all of my name and value pairs need to be...
I've setup a simple NSURLConnection to query an http-server.

I'm using NSURLConnection as listed below. I have three questions about this class. When I concatenate the url value, the debugger hits this line twice but not the line above it:
if (theConnection){
The second time I get EXC_BAD_ACCESS. Using the first url assignment (commented out) works fine.
1.) What's the difference?

In my iPhone app, i am trying to display an image on iphone from my server, which needs authorization. I am trying to use NSURLConnection to get the image, but it is not asking me for the user credentials. i.e it is not at all going to didReceiveAuthenticationChallenge method. Can anyone help me with this issue.

Hello experts!
I'm trying to create a very simple app which connects to an URL and gets the contents of that URL, in this case a simple xml document. My problem is that that the request never seems to gets sent.
I have created a new project(Foundation tool) which runs from a main file. I have set the
delegate of the NSURLConnection to...
I have classDownload that uses NSURLConnection. I'd like to keep all of the NSURLConnection events in classDownload. ClassA wants to use classDownload but also receive notifications such as connectionDidFinishLoading, which is called Finish in classDownload. How do I get the notifications from classDownload over to ClassA?

I connect asynchronously with server each 5 seconds. The URL is the same, but POST-body is changed each time. Now I create NSURL, NSURLRequest and NSURLConnection from the scratch each time.
I think it'd be more effective to set connection once and just use that one further.
I am a newbie and not sure if that possible. There is no muta...
Hi everone,
I'm interested in iPhone HTTPS through NSURLConnection, it's possible to send a request, respond to a challenge and load the secure URL. Is there anything else that can be done with NSURLConnection via HTTPS?
Thank you in advance!

Hi Team,
Had a question related to best practices in iPhone login authentication using asynchronous NSURLConnection.
Since the same delegate is used for logging into a server, how do folks differentiate notifications coming back for an authentication request, versus when you recieve data for subsequent data requests?
Thanks,

Is it possible to download an entire folder of files from my server to the user's iPhone rather than just one file at a time?
Also, is the NSURLConnection class the way to go?
Also, should I be using an HTTP path or an ftp path? (I've gotten the download of a single file to work with the HTTP, but don't know how to with the ftp or even...
