ios - 带分页的 ScrollView

Question

我在 Storyboard 中放置了一个 ScrollView ，我也启用了分页，我为 ScrollView 创建了导出，我以编程方式添加了 4 个 uiview。现在我需要水平地使用这 4 个 uiview 进行分页。请帮助我做......提前致谢

这是我的代码

- (void)scrollingView
{
    UIView *pageView1 = [[UIView alloc]init];    
    pageView1.frame = CGRectMake(0,0,self.scrollView.frame.size.width,self.scrollView.frame.size.height);    

    pageView1.backgroundColor = [UIColor blueColor];
    [self.scrollView addSubview:pageView1];

    UIView *pageView2 = [[UIView alloc]init];
    pageview2.frame = CGRectMake(0,0,self.scrollView.frame.size,width,self.scrollView.frame.size.height);

    pageView2.backgroundColor =[UIColor GrayColor];
    [self.scrollView addSubview:pageView2];
}

Answer 1

xPosition = 0;
    for (int i = 0; i<3; i++)
    {
        scrollView.clipsToBounds = YES;
        //Views
        UIView *views = [[UIView alloc]initWithFrame:CGRectMake(xPosition, 0, selfView.frame.size.width, scrollView.frame.size.height)];
        views.clipsToBounds = YES;

        [arrayOfViews addObject:views];
        xPosition += selfView.frame.size.width;

        [scrollView addSubview:views];
    }
    scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * arrayOfViews.count, scrollView.frame.size.height);

并实现scrollview委托(delegate)方法

-(void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    CGFloat pageWidth = self.scrollView.frame.size.width;
    float fractionalPage = self.scrollView.contentOffset.x / pageWidth;
    NSInteger page = lround(fractionalPage);
    self.pageCnt.currentPage = page;
}
