RestKit Timeout Being ignored

Question

I am calling a webservice from my iOS app which can take up to four minutes to return. I am using RestKit for the call and loading of the objects. What I'm finding is that when the requests are taking a long time, I get a Timeout error after ~60 seconds. I have tried setting the timeoutInterval to absurd amounts but it still times out after ~60.

RKObjectManager* objectManager = [RKObjectManager objectManagerWithBaseURL:HOSTNAME];

objectManager.client.requestQueue.showsNetworkActivityIndicatorWhenBusy = YES;
objectManager.client.disableCertificateValidation = YES;

//timeout
objectManager.client.timeoutInterval = 1000;

Here is the call to the service:

- (void)loadData 
{

NSString *uid = [self retrieveFromUserDefaults:@"login_preference"];
NSString *pwd = [self retrieveFromUserDefaults:@"password_preference"];

if([uid isEqualToString:@""] || [pwd isEqualToString:@""]){
    [self stopSpinner];
    [self enableUserInterface:YES];
    UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Missing Settings" 
                                                    message:@"Please enter your login information in the settings."
                                                   delegate:nil 
                                          cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
    return;

}


RKObjectManager* objectManager = [RKObjectManager sharedManager];
NSDictionary *params = [NSDictionary dictionaryWithObjects: 
                        [NSArray arrayWithObjects:uid, pwd, nil] 
                                                   forKeys:[NSArray arrayWithObjects:@"uid", @"pwd", nil]]; 

// Load the object model via RestKit    
[objectManager loadObjectsAtResourcePath:[@"/synchData" appendQueryParams:params] delegate:self];

}

I'm doing the call to the webservice in a background thread - is there something in that design that could be causing the problem? I can't imagine what, like iOS not letting background threads run for longer than 60 seconds? I just can't figure out what is the problem.

Is the timeout the time it takes to get a response from the server, or to get the WHOLE response from the server? I am returning a potentially very large json response - do I need to return the whole thing within the timeout limit, or do I just need to get any response from the server within the limit?

If I understand your problem, the solution would be:

- (void)request:(RKRequest *)request didFailLoadWithError:(NSError *)error

So when you have problem with timeout interval, it will be caught at this method.
