I'm using a NSMutableURLRequest to connect to a web site to get a JSON response. I'm doing so by generating the request, and then using NSURLConnection with a delegate of self to handle the async connection. I've implemented all the normal delegate methods: - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data...
iphone sdk question: I need to login to a web app and keep the session (session cookie) and then get an xml feed. I haven't found a good example for this. ...
i have set up a nsurl which grabs the data from http. when i run instrument, it says i have a leak NSFNetwork object. and how do i release theConnection in (void)ButtonClicked? or it will be release later on? - (void)ButtonClicked { NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:KmlUrl] ...
The title to this question says it all. NSURLRequest + NSHTTPURLResponse is clearly the way to role. How do I just grab the header info? Cheers, Doug ...
I am trying to use NSURLRequest with NSURLConnection to establish a binary stream connection to an HTTP server to retrieve a humungous data file in small, incrementally pieces. I see the method - (NSInputStream *)HTTPBodyStream on NSURLRequest. Is that the method I want to call on my instance of NSURLRequest? If so why does it alway ret...
I am pulling my hair out trying to conjure up the correct syntax to set the HTTP header information do a byte-range load from an HTTP server. This is the offending method on NSMutableURLRequest - (void)setValue:(NSString *)value forHTTPHeaderField:(NSString *)field This is how I am using this method to load the first 512 byte of a URL...
I have a tableView with a list of items. When a selection is made, a new view controller is pushed on the tableView's navigationController viewController stack. My question is this: one of the views in the view hierarchy associated with the pushed view controller requires the fetching of data from the network before it can render it's c...

I'm trying to figure out how to use the URL loading framework to load URLs taking advantage of caching. I am using NSURLConnections and feeding them NSURLRequests. I have even set the cachePolicy on those requests to NSURLRequestReturnCacheDataElseLoad. The first time I load a request, it does automatically get put in the cache ([NSUR...
I am loading a UIWebview and requesting a URL that can take some time to finish loading. The request starts and begins to receive data. However, it doesn't appear that the request finishes. The webViewDidFinishLoad never triggers nor does the webView didFailLoadWithError: callback. Does a timeout of a NSURLRequest only occur if ther...
I have multiple views which make the same NSURLRequest/NSURLConnection request. Ideally, in order to get some code reuse, I'd like to have some sort of a "proxy" which does all the underlying work of creating/executing the (asynchronous) request/connection, setting up all the delegate methods, etc., so I don't have to copy all those NSUR...
My iPhone application was rejected solely for using the (very safe, it seems) private method +setAllowsAnyHTTPSCertificate:forHost: for NSURLRequest. Is there a non-private API to emulate this functionality? ...
Dumb question, but how do I check if a file exists on a web site. I am using NSURLConnection with my NSURLRequest and an NSMutableData object to store what comes back in the didReceiveData delegate method. In the connectionDidFinishingLoading method I then save the NSMutableData object to the file system. All good. Except if the file...
I am trying to upload a profile image to twitter using their API. I found some good examples on the web on how to format the URLRequest, however I just can't seem to get this to work. Any help would be appreciated. The URL that I am using from Twitter API is http://twitter.com/account/update_profile_image.json -(void)uploadImageForAccou...
I need to modify response headers in an NSURLResponse. Is this possible? ...
Apple says, NSURL is developed using RFC 1738 (and some others). Now RFC 1738 specifies only that an web URL has a scheme and a scheme specific part. I want to know all the schemes which NSURL understands. And because I use it with NSURLRequest and NSURLConnection (the so called "URL Loader System"), I must know all the schemes which ...
Well, NSURLProtocol is pretty generic right? It is for defining all kinds of protocols, isn't it? So why is there nothing like NSHTTPURLProtocol? Instead, there is an informal category on NSURLRequest with specific HTTP stuff. Why did they do that this way? Why no custom HTTP protocol instead? What's the idea behind putting all this st...
I am posting (HTTP POST) various values to the posterous api. I am successfully able to upload the title, body, and ONE media file, but when I try to add in a second media file I get a server 500. They do allow media and media[] as parameters. How do I upload multiple files with the iPhone SDK? ...
