Okay So I'm having real trouble trying to get my pageControl to cooperate with my scroll. I tried different functions but I can seem to get it right. I'm able to call the right amount of views such as the white dots match the number of pictures I have but the dots don't move when I scroll from one picture to the other. How would you connect my pageControl to my scroll so when I scroll left and right it will respond the the pageControl?
// Number of views
var numberOfViews = picSource.count
var picNum:CGFloat = CGFloat(picSource.count)
// Image Scroller
let scroll = UIScrollView(frame:CGRectMake(-5, 650, screenWidth, 260))
scroll.pagingEnabled = true
scroll.showsHorizontalScrollIndicator = false
scroll.showsVerticalScrollIndicator = false
scroll.contentSize = CGSizeMake(picNum*screenWidth, 220)
scroll.delegate = self
let pageControl = UIPageControl(frame: CGRectMake(0, 600, 100, 25))
pageControl.numberOfPages = numberOfViews
pageControl.currentPage = 0
pageControl.addTarget(self, action: "pageControlSwipe:", forControlEvents: UIControlEvents.ValueChanged)
pageControl.backgroundColor = UIColor.redColor()
pageControl.userInteractionEnabled = true
self.view.bringSubviewToFront(pageControl)
border.addSubview(pageControl)
// pageControl swipe
func pageControlSwipe(sender: AnyObject) -> () {
let x = CGFloat(pageControl.currentPage) * scroll.frame.size.width
scroll.setContentOffset(CGPointMake(x, 0), animated: true)
}
func scrollViewDidEndDecelerating(scroll: UIScrollView) -> () {
let pageNumber = round(scroll.contentOffset.x / (scroll.frame.size.width))
pageControl.currentPage = Int(pageNumber)
}
