UIScrollViewDelegate Protocol Reference

UIScrollViewDelegate是UIScrollView的核心代理，我们可以通过它监听UIScrollView的相关动作。

1 Responding to Scrolling and Dragging

// 滚动持续中@available(iOS 2.0, *)optional public func scrollViewDidScroll(scrollView: UIScrollView)// 手指触摸开始滚动@available(iOS 2.0, *)optional public func scrollViewWillBeginDragging(scrollView: UIScrollView)// 手指离开屏幕后，移动速度@available(iOS 5.0, *)optional public func scrollViewWillEndDragging(scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>)// 手指离开屏幕后，是否有减速动画@available(iOS 2.0, *)optional public func scrollViewDidEndDragging(scrollView: UIScrollView, willDecelerate decelerate: Bool)// 能否滚动到头部@available(iOS 2.0, *)optional public func scrollViewShouldScrollToTop(scrollView: UIScrollView) -> Bool// 滚动到头部@available(iOS 2.0, *)optional public func scrollViewDidScrollToTop(scrollView: UIScrollView)// 手指离开屏幕后，滚动视图滚动开始减速动画func scrollViewWillBeginDecelerating(scrollView: UIScrollView)  // 手指移动引起的滚动动画结束func scrollViewDidEndDecelerating(scrollView: UIScrollView)

2 Managing Zooming

// 返回要缩放的View@available(iOS 2.0, *)optional public func viewForZoomingInScrollView(scrollView: UIScrollView) -> UIView?// 开始缩放@available(iOS 3.2, *)optional public func scrollViewWillBeginZooming(scrollView: UIScrollView, withView view: UIView?)// 缩放持续中@available(iOS 3.2, *)optional public func scrollViewDidZoom(scrollView: UIScrollView)// 缩放停止@available(iOS 2.0, *)optional public func scrollViewDidEndZooming(scrollView: UIScrollView, withView view: UIView?, atScale scale: CGFloat)

3 Responding to Scrolling Animations
