UIScrollView

UIScrollView是所有滑动视图的基类

UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(100, 100, 200, 200)];

scroll.background = [UIColor redColor];

scroll.contentSize = CGSizeMake(2000, 2000); //设置UIScrollView的内容区域大小, 当UIScrollView的内容大小大于UIScrollView的Frame的大小时,UIScrollView可以滑动.

scroll.contentOffset = CGPointMake(200, 0); //设置UIScrollView的内容偏移量.

scroll.showHorizontalScrollIndicator = NO; //关闭水平的滑动指示条

scroll.showVerticalScrollIndicator = NO; //关闭竖直的滑动指示条

scroll.scrollEnabled = NO; //禁止UIScrollView滑动

scroll.pagingEnabled = YES; //允许UIScrollView整页滑动

scroll.directionalLockEnabled = YES; //设置UIScrollView的单向滑动

scroll.bounces = NO; //禁止UIScrollView的边界反弹效果.

scroll.alwaysBounceHorizontal = YES; //即使内容的size大小小于ScrollView的frame的大小, 依然具有边界反弹效果.

scroll.alwaysBounceVertical = YES;

scroll.scrolsToTop = NO; //禁止点击状态条滑动到顶部.

scroll.maximumZoomScale = 4.0; //设置UIScrollView的缩放最大最小值

scroll.minimumZoomScale = 0.5;
