How to set timeout interval for RESTKIT Object Manager

I am using the RESTKIT Object Manager to get information from my server. The snippet of my implementation code is as follows:

-(void)getObjects
{
    //Instantiate the RestKit Object Manager
    RKObjectManager *sharedManager = [RKObjectManager sharedManager];

    //show the spinner
    [self showLoading];

    //call server with the resourcepath
    [sharedManager loadObjectsAtResourcePath:self.resourcePath delegate:self];
}

- (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects:(NSArray*)objects 
{

    // handling in scenarios of empty arrays
    if ( [objects count]==0 ){
        [self hideLoading];
        if (emptyHandler){
            emptyHandler();
        }else{
            [self standardEmptyHandling];            
        }
        return;
    }

    // planned failure
    if ( [[objects objectAtIndex:0] isKindOfClass:[Failure class]]){
        NSAssert([objects count]==1,@"object returned is type failure, but there are more than one object in it");
        failureObject=[object开发者_JS百科s objectAtIndex:0];
        [self hideLoading];
        [self standardErrorHandling];
        return;
    }

    //return completion block to caller
    completionHandler(objects);

}

However there might be cases whereby there is a server error or reachability error this causing the process to continue trying for a long duration before terminating (spinner will be displayed for an extended amount of time_.

Is there a way to set a timeout duration in my implementation so that I can prompt the user an alert to try again if the server does not respond in 20 secs for example?

This has now been resolved by RestKit contributors in this pull request https://github.com/RestKit/RestKit/pull/491 and can be set easily as follows:

RKObjectManager *objectManager = [RKObjectManager objectManagerWithBaseURL:@"http://..."];
objectManager.client.timeoutInterval = 30.0; // 30 seconds

Apple's default timeout for URL requests is 60 secs.

Here is a discussion about the pending issue in RestKit:

A NSTimer could be an easy way around.

#pragma mark - RKRequestDelegate
- (void)requestDidStartLoad:(RKRequest *)request {
   [NSTimer scheduledTimerWithTimeInterval:20.0
       target:self
       selector:@selector(handleRequestTimeout)
       userInfo:nil
       repeats:NO];
}
