ScrollView
继承于 UIResponder
属性
contentSize 滚动范围 CGSizeMake 默认为(0.0)
contentOffset 滚动偏移量 CGPointMake 默认为CGPointZero
contentInset 滚动区域四周的滚动范围 UIEdgeInsetsMake
directionalLockEnabled 锁定垂直或水平滚动
bounces 边缘回弹效果
alwaysBounceHorizontal 存在水平弹动效果
alwaysBounceVertical 存在垂直弹动效果
pagingEnabled 按页滚动
scrollEnabled 能否滚动
showsHorizontalScrollIndicator 显示水平滚动条
showsVerticalScrollIndicator 显示垂直滚动条
scrollIndicatorInsets 滚动条边距 UIEdgeInsetsMake
indicatorStyle 滚动条颜色
// UIScrollViewIndicatorStyleDefault,
// UIScrollViewIndicatorStyleBlack,
// UIScrollViewIndicatorStyleWhite
scrollsToTop 双击回顶部
keyboardDismissMode 键盘消失模式
minimumZoomScale 缩放最小
maximumZoomScale缩放最大
如果想进行视图的缩放,必须实现viewForZoomingInScrollView
-(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView{
return [scrollView.subviews firstObject];
}
scrollView.tracking 是否开始拖动 scrollView.isTracking
scrollView.dragging 是否正在拖动 scrollView.isDragging
scrollView.decelerating 是否正在减速scrollView.isDecelerating
添加代理
@interface ViewController ()<UIScrollViewDelegate>
@end
实现方法:
scrollViewWillBeginDragging: 滚动视图将要开始拖拽
scrollViewDidEndDragging: 滚动视图已经结束拖拽
scrollViewWillBeginDecelerating: 将要开始减速
scrollViewDidEndDecelerating: 已经结束减速
