• iOS UIScrollView基本用法和代理方法


    - (void)viewDidLoad{

    [superviewDidLoad];

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

    scrollView.backgroundColor = [UIColorredColor];

    // 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,lockscrollView.directionalLockEnabled =YES;

    [self.view addSubview:scrollView];

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

    label.backgroundColor = [UIColoryellowColor];label.text =@"学习scrolleview";

    [scrollView addSubview:label];[label release];}#pragma mark -/*

    // 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 *)view atScale:(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{returnYES;}

    // 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");
