I will be putting up the Obj-C code in the CVS repository at SourceForge most likely by Thursday this week. Downloading is 7 lines of code (not counting the XML parsing of the list that comes back):
NSString* hostName = [NSString stringWithFormat:@"%d.%d.%d.%d:%d", classA, classB, classC, classD, port];
NSURL* url = [[NSURL alloc] initWithScheme:@"http" host:hostName path:@"/list?filetype=mm"];
NSError* error;
XMLReader* reader = [[XMLReader alloc] init];
[reader parseXMLFileAtURL:url parseError:&error];
[url release];
url = nil;
Uploading is a little more:
NSMutableURLRequest* request = [[NSMutableURLRequest alloc] initWithURL:fileURL];
[request setHTTPMethod:@"PUT"];
[request setHTTPBody:putData];
NSHTTPURLResponse* response;
NSError* error;
[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString* errorText = nil;
if (response == nil) {
errorText = [response description];
else if ([response statusCode] != 200) {
errorText = [[NSString alloc] initWithFormat:@"Received error code %d.", [response statusCode]];
[request release];
[response release];
[error release];
return errorText;
Setting up the URLs and such based on the information from Bonjour adds a little more. Parsing the list of files (an HTML list is returned by the client) is based off of the SeismicXML demo, provided by Apple. The list returned just so happens to also be valid XML (of course, I made it that way).
I've also integrated parts of the Bonjour demo provided by Apple to handle the Bonjour stuff. The Obj-C code is really rough right now, so if you could help me work out the kinks, that would be great. There's probably way more code than is needed right now, since it's mostly based on Apple demos.
Right now, the code doesn't handle conflicts at all, so that will have to be worked on as well.
