nsurlconnection

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 - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error - (void)connectionDidFinishLoading:(NSURLConnection *)connection All works perfectly with getting data back, dealing with any errors that occur, etc. However with the timeout on

I'm using [NSURLConnection connectionWithRequest:req delegate:self]; and then I use -(BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace; -(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge; -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error; -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response; -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data; -(void

I'm trying to get a list of assests urls to download. I'm using NSURLConnection in order to get a JSON file that have this list of urls. in - (void)connection:(NSURLConnection *)connection didWriteData:(long long)bytesWritten totalBytesWritten:(long long)totalBytesWritten I'm getting 122239 as total bytes written. when - (void)connectionDidFinishDownloading:(NSURLConnection *)connection destinationURL:(NSURL *)destinationURL is called I'm trying to read the url data in order to extract the JSON file: NSData *data = [NSData dataWithContentsOfURL:destinationURL options:NSDataReadingUncached

I've seen a lot of code, including Apple's SimpleURLConnections sample, that simply cast any NSURLResponse to a NSHTTPURLResponse. If it is always a NSHTTPURLResponse why do the NSURLConnections not return NSHTTPURLResponse? I'm worried that if I simply downcast the response, I'm introducing buggy code. For instance, is it OK to do this without checking isKindOfClass? - (NSURLRequest *)connection:(NSURLConnection *)connection willSendRequest:(NSURLRequest *)request redirectResponse:(NSURLResponse *)redirectResponse { NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)redirectResponse; // do

NSURLConnection *connection is a property of the class @property (nonatomic, retain) NSURLConnection *connection; Instruments is reporting that I'm leaking an NSURLConnection object in the second line of the code below. NSURLRequest *request = [[NSURLRequest alloc] initWithURL:_url]; self.connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; [request release]; In the didFinishLoading and didFinishWithError delegate selectors, I'm releasing the connection and setting to nil [self.connection release]; self.connection = nil; I've read the "NSURLConnection leak?" post and

I want to send a large amount of data to a server using NSURLConnection (and NSURLRequest ). For this I create a bound pair of NSStream s (using CFStreamCreateBoundPair(...) ). Then I pass the input stream to the NSURLRequest ( -setHTTPBodyStream: ) and schedule the output stream on the current run loop. When the run loop continues, I get the events to send data and the input stream sends this data to the server. My problem is, that this only works when the data fits into the buffer between the paired streams. If the data is bigger, then somehow the input stream gets an event (I assume "bytes
