Usage

YGHorizontalScroller works by wrapping sroller and UIViews together and offers a flexiable protocal with methods. To make use of methods don't forget to import YGHorizontalScroller into your code:

import YGHorizontalScroller

Note: If you encounter an import error, building your project may resolve the problem

You can create the scroll view by:

scroller = YGHorizontalScroller(frame: CGRect(x: 0, y: 100, width: screenWidth, height: 300))
view.addSubview(scroller)

scroller.viewWidth = 200
scroller.viewHeight = 300
scroller.viewPadding = 10
scroller.viewOffset = 100
  
scroller.delegate = self
scroller.reload()

Then implement YGHorizontalScrollerDelegate protocol:

func numberOfViews(scroller: YGHorizontalScroller) -> Int {
  return images.count
}
  
func cellForViewAtIndex(scroller: YGHorizontalScroller, index: Int) -> UIView {
  let image = images[index]
  let imageView = UIImageView(image: image)
      
  if currentIndex == index {
    imageView.backgroundColor = UIColor.whiteColor()
  } else {
    imageView.backgroundColor = UIColor.blackColor()
  }
    
  return imageView
}
  
func didSelectViewAtIndex(scroller: YGHorizontalScroller, index: Int) {
  let previousView = scroller.viewAtIndex(currentIndex)
  previousView.backgroundColor = UIColor.blackColor()
    
  currentIndex = index
    
  let currentView = scroller.viewAtIndex(currentIndex)
  currentView.backgroundColor = UIColor.whiteColor
}
  
func initialViewIndex(scroller: YGHorizontalScroller) -> Int {
  return 0
}
