Accepted Answer

In the iCarousel `carouselCurrentItemIndexUpdated:` delegate method, set

```
pageControl.currentPage = carousel.currentItemIndex / 5
```

Then bind your pageControl action to a method like the one below:

```
- (IBAction)updatePage:(UIPageControl *)pageControl
{
    [carousel scrollToItemAtIndex:pageControl.currentPage * 5 aimated:YES];
}
```

If you're not using a nib file, you can bind the action using

```
[pageControl addTarget:self action:@selector(updatePage:) forControlEvents:UIControlEventValueChanged];
```

It's a good idea to set `pageControl.defersCurrentPageDisplay = YES;` as well to avoid flicker.
