hmsegmentedcontrol - When I scroll, the tab highlighter always changes to 0. why?

Question

In HMSegmentControl, I have added tableview in one of the segment View. When I am on the current section and I scroll up or down, I noticed that the tab highlighter always changes to 0. Why is it happening?

This is my scrollView code:

-(void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    CGFloat pageWidth = scrollView.frame.size.width;
    int page = scrollView.contentOffset.x / pageWidth;
    [self.chatSegment setSelectedSegmentIndex:page animated:YES];
    NSLog(@"scrollViewDidScroll - You are now on page %i",page);
}

Log Value:

<UITableView: 0x128007e00; frame = (0 0; 320 568); clipsToBounds = YES; tag = 502; gestureRecognizers = <NSArray: 0x1276c2690>; layer = <CALayer: 0x1276c20e0>; contentOffset: {0, 2}; contentSize: {320, 570}>

we don't know what HMSegmentedControl is! Did you log the page value ? Is it 0 while you scroll ? — Teja Nandamuri, Aug 26 '16 at 13:59
and that makes the segment to select the 0 index. Are you asking why do you get 0 for scrollView content offset ? — Teja Nandamuri, Aug 26 '16 at 14:03
you should add more details. what is the scrollview content size ? — Teja Nandamuri, Aug 26 '16 at 14:05
ok. I have add object value. scrollview content size is contentSize: {320, 570} — Balasubramanian, Aug 26 '16 at 14:09

When a table is scrolled in vertical direction, the offset y value will be changed , x value will always be 0.

So in you case, you should refer to scrollView.contentOffset.y
