Hello friends

If you are loading to a specific count data to a UITableView and you need to add more data on "refresh"(i.e PULL TO REFRESH) then I have some help here.

Add protocol to Landing screen class and declare a method name : -(void)responseDict:(id)response tagValue:(int)tagValue;

LandingScreenAgentClass

-(void)gettingMoreDetail:(NSString *)make andStart:(NSString *)start andCount:(NSString *)count andModel:(NSString *)model andYear:(NSString *)year andReviewId:(NSString *)reviewId andladingArrayCount:(int)arrayCount delegate:(UIViewController<LandingScreenDelegate>*)del
{
    tagValue=2;
    self.delegate = del;

//    start=(NSString *)arrayCount;

    NSString *urlString=[NSString stringWithFormat:@"%@%@?make=%@&reviewId=%@&start=%d&count=%@",BASE&#95;URL&#95;FOR&#95;USER,BASE&#95;URL&#95;FOR&#95;FETCHING&#95;REVIEWS,@"dukati",reviewId,arrayCount,count];
    NSLog(@"url is %@",urlString);
    ASIHTTPRequest *request = [[ASIHTTPRequest alloc]initWithURL:[NSURL URLWithString:urlString]];
    [request setDelegate:self];
    [request setTimeOutSeconds:60];

    [request setDidFailSelector:@selector(setDidFailSelectorLanding:)];
    [request setDidFinishSelector:@selector(setDidFinishSelectorLanding:)];
    [request startAsynchronous];

}

ViewControllerImplementation

pragma mark LandingScreenDelegates

-(void)responseDict:(id)response tagValue:(int)tagValue
{

                    NSDictionary *dict = (NSDictionary *)response;


                    NSLog(@"dictdict====landing========%@",dict);

                    NSDictionary *status=[dict objectForKeyWithNullCheck:@"status"];
                    NSString *statuscode = [status objectForKeyWithNullCheck:@"code"];
                    NSString *description =[status objectForKeyWithNullCheck:@"description"];

                    if ([statuscode isEqualToString:STATUS_CODE]&&[description isEqualToString:STATUS_DESCRIPTION])
                    {

                        NSArray *dictReview = [dict objectForKeyWithNullCheck:@"review"];
                        NSMutableArray *dictArrayDelegate=[NSMutableArray new];
                        for (NSDictionary *dictValue in dictReview)
                        {
                            ReviewModel *reviewModal=[[ReviewModel alloc]initWithDictionary:dictValue];
                            [dictArrayDelegate addObject:reviewModal];

                        }
                        NSLog(@"DICT ARRAY IS %@",dictArrayDelegate);
                        if (dictArray==nil) {
                            dictArray = [[NSMutableArray alloc]init];
                        }
                        [dictArray addObjectsFromArray:dictArrayDelegate];
//                        dictArray = [[NSArray alloc]initWithArray:dictArrayDelegate];
//                        [activityIndicator setHidden:YES];
                        [carTable reloadData];
                    }
                    else if([statuscode isEqualToString:STATUS_FAILED])
                    {
                        [Utils showAlert:@"Messages" message:@"Nothing fetched"];
                    }


   atuscode isEqualToString:STATUS_FAILED])
            {
                [Utils showAlert:@"FAIL" message:@"Failed Hit"];
            }

            }
   }

For making a pull to refresh you need to user Scroll view delegates

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate
{

    NSLog(@"cartablecobntentoffset%f",carTable.contentOffset.y);

    NSLog(@"scrollview frame %f",scrollView.frame.size.height);

    NSLog(@"MIXED %f",((carTable.contentSize.height+carTable.frame.size.height)-10));

    if (carTable.contentOffset.y>((carTable.contentSize.height+carTable.frame.size.height)-700))
    {
        [carTable setScrollEnabled:NO];
        [activityIndicator setHidden:YES];

        [activityIndicator startAnimating];



        NSLog(@"car table is %f",carTable.contentOffset.y);
        LandingScreenSeverAgent *land=[[LandingScreenSeverAgent alloc]init];
        [land gettingMoreDetail:@"Toyota" andStart:@"" andCount:@"10" andModel:@"" andYear:@"" andReviewId:@"" andladingArrayCount:dictArray.count delegate:self];



    }
    [carTable setScrollEnabled:YES];

    if (carTable.contentOffset.y<700) {
//        [activityIndicator removeFromSuperview];
//        [activityIndicator setHidden:YES];
        NSLog(@"less contemt off set");
    }


}

I hope this helps you.
