Question

我正在UITableView上实施一个滑动图像演示，而且我正在使用UIPageControl。当我在第一行上滑动图像时，页面控件会正确更改，但是当我滑动第二行页面控件的图像时，它从第一行的位置开始。

这是我的代码

-(void)seePhotosBtnClicked:(UIButton *)sender
{
    photoView.hidden = NO;


    CGPoint touchPoint = [sender convertPoint:CGPointZero toView:addressTable]; // maintable --> replace your tableview name
    NSIndexPath *clickedButtonIndexPath = [addressTable indexPathForRowAtPoint:touchPoint];
    NSString *areaToSearch = [[addressInfoArray valueForKey:@"IMAGEPATH"]objectAtIndex:clickedButtonIndexPath.row];


    NSArray *urlArray = [areaToSearch componentsSeparatedByString: @","];

    for (int i = 0; i<=2; i++)
    {
        NSURL *imageURL = [NSURL URLWithString:[urlArray objectAtIndex:i]];
        NSData *imageData = [NSData dataWithContentsOfURL:imageURL];
        UIImage *image = [UIImage imageWithData:imageData];

        CGRect frame;
        frame.origin.x =pagedScrollView.frame.size.width * i;
        frame.origin.y = 0;
        frame.size = pagedScrollView.frame.size;
        UIImageView *imgView=[[UIImageView alloc]initWithFrame:frame];

        imgView.image = image;
        [pagedScrollView addSubview:imgView];

    }
     pagedScrollView.contentSize = CGSizeMake(pagedScrollView.frame.size.width * 3, pagedScrollView.frame.size.height);
        [pageControl addTarget:self action:@selector(changePage:) forControlEvents:UIControlEventValueChanged];

   }

- (void)changePage:(id)sender
{


    // update the scroll view to the appropriate page
    CGRect frame;
    frame.origin.x = pagedScrollView.frame.size.width * pageControl.currentPage;
    frame.origin.y = 0;
    frame.size = pagedScrollView.frame.size;
    [pagedScrollView scrollRectToVisible:frame animated:YES];



}

知道了，停止滚动照片的地方添加此代码。

 pageControl.currentPage=0;
    pagedScrollView.contentSize = CGSizeMake(0, pagedScrollView.frame.size.height);

现在，您的滚动视图将从第一个图像开始，页面控制从第一个刻度开始

UIPageControll无法在UITableView单元格中正常工作
