I have UITableview with pagination like first will get 20 objects from server and will populate in UITableView then when it reaches last row need to make another service call to get next 20 objects.

My problem is I need to add activity indicator at bottom of my table and should say "Loading", User can scroll to up to view current objects but should not scroll down.

Is there any custom control? Is there any best way to achieve it?.

Thanks in advance.

Let's Try TableView Footer View to show activity indicator.

For example :

Declare UIView * footerView; in .h file

Add Following methods in .m file

 - (void)viewDidLoad
 {
     [super viewDidLoad];

     [self initFooterView];
 }

 -(void)initFooterView
 {
    footerView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 40.0)];

    UIActivityIndicatorView * actInd = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];

    actInd.tag = 10;

    actInd.frame = CGRectMake(150.0, 5.0, 20.0, 20.0);

    actInd.hidesWhenStopped = YES;

    [footerView addSubview:actInd];

    actInd = nil;
 }

-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
     BOOL endOfTable = (scrollView.contentOffset.y >= ((self.contentArray.count * 40) - scrollView.frame.size.height)); // Here 40 is row height

    if (self.hasMoreData && endOfTable && !self.isLoading && !scrollView.dragging && !scrollView.decelerating)
   {
        self.tableView.tableFooterView = footerView;

        [(UIActivityIndicatorView *)[footerView viewWithTag:10] startAnimating];
   }

}

Thanks!
