nsurlconnection

I've been looking here for some answers to this question and have found some resources but not really found the "spot on" tutorial. So i would be grateful for any posts of tutorials on howto get SOAP working in an iphone app. I have seen that it can be done using NSURLconnection. But as I am pretty new to Objective C programming i would have wanted to see a step by step tutorial. Like an SOAP "Hello World" if you would like. Also, Alexander Griekspoor wrote a nice hands-on, two-part tutorial in MacResearch ( part1 ). I wrote two tutorials covering SOAP in iPhone using Google's wsdl2objc, here

I'm trying to connect to http://cmis.demo.nuxeo.org/nuxeo/atom/cmis/ with NSURLConnection . This demo web service is documented to require authentication (login: Administrator / password: Administrator). Edit : This web service now sends an authentication challenge, it was not at the time the question was asked. This web service does not send an authentication challenge, so I can't use the connection:didReceiveAuthenticationChallenge: delegate method. Instead I set a default NSURLCredential in the shared credential storage. Unfortunately, this default credential is not used by NSURLConnection

I have been trying to search for a way to unset the credentials once you set a NSURLCredential with a NSURLConnection that is using NSURLCredentialPersistenceForSession, but I couldn't find a working solution. Removing the NSURLCredential from the NSURLCredentialStorage only removes it from the storage and not from the NSURLConnection cache. I tried turning cache off and it still keeps it. I need it to be NSURLCredentialPersistenceForSession as I don't want it to be uploading the large data then getting back the you need to authenticate message then authenticating with NSURLConnection and then

I'm using the code from Apple's Document to do some HTTP communication. I can connect to the URL successfully, but I failed to receive the data from my server. // create the request NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://..."] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; // create the connection with the request // and start loading the data NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (theConnection) { // Create the NSMutableData that will hold // the received data //

I am using this function to upload an image to a server using JSON . In order to do so, I first convert the image to NSData and then to NSString using Base64 . The method works fine when the image is not very large but when I try to upload a 2Mb image, it crashes. The problem is that the server doesn't receive my image even though the didReceiveResponse method is called as well as the didReceiveData which returns (null) . At first I thought it was a time out issue but even setting it to 1000.0 it still doesn't work. Any idea? Thanks for your time! Here's my current code: - (void) imageRequest

I m using sendSynchronousRequest to get the data from the server. I know that synchronous will wait until the data received for that request. But the problem comes when user by mistake enters some non-existing url and than tries to get response. In this case, if user goes in to background and than comes into foreground it shows only black screen. It only shows status bar. Also its not showing any background application. I have to press Home button to come out of my application. On simulator, After 1+ minute it shows me the message that "Request time out" (No crash). On Device, within 1 min
