-(void)viewDidload

{
[super viewDidLoad];

  scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];

  scrollView.backgroundColor = [UIColor redColor];

// 是否支持滑动最顶端

  scrollView.scrollsToTop = NO;

  scrollView.delegate = self;

// 设置内容大小

  scrollView.contentSize = CGSizeMake(320, 460*10);

// 是否反弹

  scrollView.bounces = NO;

// 是否分页

  scrollView.pagingEnabled = YES;

// 是否滚动

  scrollView.scrollEnabled = NO;

  scrollView.showsHorizontalScrollIndicator = NO;

// 设置indicator风格

  scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite;

// 设置内容的边缘和Indicators边缘

  scrollView.contentInset = UIEdgeInsetsMake(0, 50, 50, 0);

  scrollView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 50, 0, 0);

// 提示用户,Indicators flash

  [scrollView flashScrollIndicators];

// 是否同时运动,lock

  scrollView.directionalLockEnabled = YES;

  [self.view addSubview:scrollView];

 

  UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 200, 320, 40)];

  label.backgroundColor = [UIColor yellowColor];

  label.text = @"学习scrolleview";

  [scrollView addSubview:label];

代理方法

// 返回一个放大或者缩小的视图

- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView{

// 开始放大或者缩小

- (void)scrollViewWillBeginZooming:(UIScrollView *)scrollView withView:(UIView *)view{

// 缩放结束时

- (void)scrollViewDidEndZooming:(UIScrollView *)scrollView withView:(UIView *)viewatScale:(float)scale{

// 视图已经放大或缩小

- (void)scrollViewDidZoom:(UIScrollView *)scrollView{

NSLog(@"scrollViewDidScrollToTop");

 }

 
// 是否支持滑动至顶部

- (BOOL)scrollViewShouldScrollToTop:(UIScrollView *)scrollView{

return YES;


// 滑动到顶部时调用该方法

- (void)scrollViewDidScrollToTop:(UIScrollView *)scrollView{

NSLog(@"scrollViewDidScrollToTop");

// scrollView 已经滑动

- (void)scrollViewDidScroll:(UIScrollView *)scrollView{

NSLog(@"scrollViewDidScroll");

 
// scrollView 开始拖动

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView{
NSLog(@"scrollViewWillBeginDragging");



// scrollView 结束拖动 

 - (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{
NSLog(@"scrollViewDidEndDragging");

 

// scrollView 开始减速(以下两个方法注意与以上两个方法加以区别)

- (void)scrollViewWillBeginDecelerating:(UIScrollView *)scrollView{
NSLog(@"scrollViewWillBeginDecelerating");

 

// scrollview 减速停止

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{
NSLog(@"scrollViewDidEndDecelerating");
