Thanks for a very good tutorial, it helped me a lot !
Initially even I was getting the same error that “Mike” was getting.
I hadn’t read the entire article…(I mean the replys and all)

But with my programming experience I learned that instead of creating an SBJSON,
one needs to crate SBJsonParser ‘s object.
As SBJsonParser ‘s objects would respond to / call the parser method !!

ok, does that url passed to the stringWithUrl method have to be in the format

GET
http://www……/read.php?var1=value [so u can fetch records where id=value]

or can it be

POST
http://www…./read.php [where the data is in the HTTPbody?]

I cant get the 2nd one to work.

Im working on a similar project. Im using NSURLConnection to POST data to a php file which i know works because ive tested it with an html POST form manually.

Im having the iOS app post this code:

+ (NSArray *)fetchTimelineForUDID:(NSString *)udid{

NSData *postData = [udid dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSLog(@”%@”,postData);
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.santiapps.com/iGlobe/readtags2.php"]];
[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSURLResponse *response;
NSError *error;
NSData *urlData = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:&error];
return nil;
}

at the moment i return nil just to test out NSLogs….but the thing is the NSURLConnection returns NSData. What im expected to return from this function is an NSArray. How can i make that conversion if thats what needs to be done?
