Delegate function not called on Three20 url request model

Question

In one of my project, I want to use the TTURLRequestModel to populate the response data in XML format by passing the TTURLXMLResponse to the request. However, the delegate method is never called. Can someone tell me what I am missing in these two files? Do I need to initialize some other elements of the library?

Three20Parser.h

@interface Three20Parser : TTURLRequestModel{

}

- (void) download;

@end

Three20Parser.m

#import "Three20Parser.h"
#import "extThree20XML/extThree20XML.h"

@implementation Three20Parser

- (id)init{
    self = [super init];
    return self;
}

- (void) download{
    NSString *requestURL = @"http://server.local/service.asmx";
    NSLog(@"requestURL: %@", requestURL);

    TTURLRequest *request = [TTURLRequest requestWithURL:requestURL delegate:self];
    request.cacheExpirationAge = TT_CACHE_EXPIRATION_AGE_NEVER;
    request.cachePolicy = TTURLRequestCachePolicyNone;

    TTURLXMLResponse *response = [[TTURLXMLResponse alloc] init];
    request.response = response;
    TT_RELEASE_SAFELY(response);

    [request send];
}

     /*
 the requestDidFinishLoad is not called.
 */

- (void)requestDidFinishLoad:(TTURLRequest *)request{
    //TTURLXMLResponse *response = request.response;
    //NSLog(@"response: %@", [[NSString alloc] initWithData:response.data encoding:NSUTF8StringEncoding]);

    NSLog(@"REQUEST DID FINISH", nil);
}

Hi,

Perhaps the request failed? You're only implementing the success method of the protocol - does request:didFailLoadWithError: get called instead?

I'd implement every method possible just for debugging to see what's going on. Then when you've got it working, remove the onls you don't need.

However, you should always check for errors - you might have to tell the user it has failed for Apple to allow the app into the app store! Even if you don't have to tell the user, you should probably do something about it!
