UIScrollView Class Reference

UIScrollView是一个很强大的类，它能提供比手机界面更大的空间给用户查看。如一张很大的图片，用户即可在手机上移动和捏合查看图片。

UIScrollView向下延生了三个子类UICollectionView、UITableView和UITextView。这都是我们工作中常用的View。

1 Managing the Display of Content

// 动态设置原点，即移动public func setContentOffset(_ contentOffset: CGPoint, animated animated: Bool)// 原点所对应的contentview的坐标public var contentOffset: CGPoint// 可移动的区域public var contentSize: CGSize// contentview和边的距离public var contentInset: UIEdgeInsets 

2 Managing Scrolling

// 能否滚动public var scrollEnabled: Bool// 锁定某个方向的滚动public var directionalLockEnabled: Bool// 能否自动回到顶部public var scrollsToTop: Bool// 可视区域public func scrollRectToVisible(rect: CGRect, animated: Bool)// 以页的形式滚动public var pagingEnabled: Bool// 全局滚动阻力public var bounces: Bool // y轴滚动阻力public var alwaysBounceVertical: Bool// x轴滚动阻力public var alwaysBounceHorizontal: Bool// 手势事件是否响应public func touchesShouldBegin(touches: Set<UITouch>, withEvent event: UIEvent?, inContentView view: UIView) -> Bool// 是否取消子视图public func touchesShouldCancelInContentView(view: UIView) -> Bool// 是否延迟处理触摸事件public var delaysContentTouches: Bool// 是否触摸导致跟踪public var canCancelContentTouches: Bool// 滚动的速度public var decelerationRate: CGFloat// 用户是否触摸屏幕public var tracking: Bool { get } // 是否在滚动public var dragging: Bool { get }// 是否在减速动画public var decelerating: Bool { get }

3 Managing the Scroll Indicator

// 滚动条的样式public var indicatorStyle: UIScrollViewIndicatorStyle// 滚动条的位置public var scrollIndicatorInsets: UIEdgeInsets// 是否显示x轴滚动条public var showsHorizontalScrollIndicator: Bool// 是否显示y轴滚动条public var showsVerticalScrollIndicator: Bool// 随时显示滚动条public func flashScrollIndicators()

4 Zooming and Panning

// UIPanGestureRecognizer手势@available(iOS 5.0, *)public var panGestureRecognizer: UIPanGestureRecognizer { get }// UIPinchGestureRecognizer手势@available(iOS 5.0, *)public var pinchGestureRecognizer: UIPinchGestureRecognizer? { get }// 是否缩放动画@available(iOS 3.0, *)public func zoomToRect(rect: CGRect, animated: Bool)// 缩放比例@available(iOS 3.0, *)public var zoomScale: CGFloat// 动画设置缩放比例@available(iOS 3.0, *)public func setZoomScale(scale: CGFloat, animated: Bool)// 缩放的最小比例public var minimumZoomScale: CGFloat// 缩放的最大比例public var maximumZoomScale: CGFloat //缩放阻力效果public var bouncesZoom: Bool // 用户是否在进行缩放操作public var zooming: Bool { get }// 是否超过缩放指定的比例限制public var zoomBouncing: Bool { get }

5 Managing the Delegate

// 回调代理weak public var delegate: UIScrollViewDelegate?

6 Managing the Keyboard

// 键盘与滚动交互@available(iOS 7.0, *)public var keyboardDismissMode: UIScrollViewKeyboardDismissMode
