Iphone UIScrollView按钮分页

我一直在尝试制作一个100x100像素的滚动视图（分页模式），每页显示一个75x75的按钮。我可以看到第一张图片，但无法转到下一张。这是我一直在使用的代码，有人能帮我吗

h

m

@菜单；
-（无效）viewDidLoad{
scrollMenu.PaginEnabled=是；
NSInteger numberOfButtons=2；
对于（int i=0；i

除了UIImageView之外，我还实现了类似的功能。在这里，您只需要设置UI ScrollView的一些属性，并需要实现一个委托方法

首先设置一些属性

- (void)viewDidLoad
{
    [super viewDidLoad];

    _scrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
    _scrollView.multipleTouchEnabled=YES;
    _scrollView.scrollEnabled=YES;
    _scrollView.directionalLockEnabled=YES;
    _scrollView.canCancelContentTouches=YES;
    _scrollView.delaysContentTouches=YES;
    _scrollView.clipsToBounds=YES;
    _scrollView.alwaysBounceHorizontal=YES;
    _scrollView.bounces=YES;
    _scrollView.pagingEnabled=YES;
    _scrollView.showsVerticalScrollIndicator=NO;
    _scrollView.showsHorizontalScrollIndicator=NO;
    _scrollView.delegate=self;

}

实现委托方法

-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    @try
    {
        CGFloat pageWidth = 320;    //scrollView.frame.size.width;
        int page = floor((scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;

        if (page >9)
            page = page - 3;
        if (page <[listOfPictures count])
        {
            [_scrollView setContentOffset:CGPointMake(320*page, _scrollView.contentOffset.y) animated:YES];
            currentPicIndex = page;
        }

    }
    @catch (NSException *exception)
    {
        TRACE_ERROR(@"scrollViewDidEndDecelerating", exception.name, exception.description);
    }

}

-（无效）ScrollViewDiEndDecelling:（UIScrollView*）scrollView
{
@试一试
{
CGFloat pageWidth=320；//scrollView.frame.size.width；
int page=floor（（scrollView.contentOffset.x-pageWidth/2）/pageWidth）+1；
如果（第9页）
第页=第3页；
如果（页面），谢谢，但我不认为这是我要找的。
- (void)viewDidLoad
{
    [super viewDidLoad];

    _scrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
    _scrollView.multipleTouchEnabled=YES;
    _scrollView.scrollEnabled=YES;
    _scrollView.directionalLockEnabled=YES;
    _scrollView.canCancelContentTouches=YES;
    _scrollView.delaysContentTouches=YES;
    _scrollView.clipsToBounds=YES;
    _scrollView.alwaysBounceHorizontal=YES;
    _scrollView.bounces=YES;
    _scrollView.pagingEnabled=YES;
    _scrollView.showsVerticalScrollIndicator=NO;
    _scrollView.showsHorizontalScrollIndicator=NO;
    _scrollView.delegate=self;

}

-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    @try
    {
        CGFloat pageWidth = 320;    //scrollView.frame.size.width;
        int page = floor((scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;

        if (page >9)
            page = page - 3;
        if (page <[listOfPictures count])
        {
            [_scrollView setContentOffset:CGPointMake(320*page, _scrollView.contentOffset.y) animated:YES];
            currentPicIndex = page;
        }

    }
    @catch (NSException *exception)
    {
        TRACE_ERROR(@"scrollViewDidEndDecelerating", exception.name, exception.description);
    }

}
