UIScrollView 图片循环滚动

1：假如有6个图片：那个，Scrollview的大小加 7 个图片的大小

2:

  //ImageScrollView;
    UIScrollView *imageScroll = [[UIScrollView alloc]initWithFrame:CGRectMake(, , , )];
    imageScroll.bounces = YES;
    imageScroll.pagingEnabled = YES;
    imageScroll.userInteractionEnabled = YES;
    imageScroll.showsVerticalScrollIndicator = NO;
    imageScroll.showsHorizontalScrollIndicator = NO;
    imageScroll.delegate = self;
    imageScroll.contentSize = CGSizeMake( * , );
    [theScrollView addSubview:imageScroll];
    [imageScroll release];

    //加上图片；
    for (int i = ; i < ; i++) {
        UIImageView *aImageView = [[UIImageView alloc]initWithFrame:kCR( + *i, , , )];
        aImageView.image = [UIImage imageNamed:[NSString stringWithFormat:@"keenLC%d.jpg",i+]];
        if (i==) {
            aImageView.image = [UIImage imageNamed:[NSString stringWithFormat:@"keenLC%d.jpg",]];
        }

        [imageScroll addSubview:aImageView];
        [aImageView release];

    }
    //图片数字label
    imageNumLabel = [[UILabel alloc]initWithFrame:kCR(, imageScroll.bottom - , , )];
    imageNumLabel.text = @"1/6";
    imageNumLabel.textAlignment = NSTextAlignmentCenter;
    imageNumLabel.textColor = [UIColor whiteColor];
    imageNumLabel.backgroundColor = [UIColor clearColor];
    [theScrollView addSubview:imageNumLabel];
    [imageNumLabel release];

3: ScrollView的代理

#pragma mark Scroll delegate
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView;{
    int currentPage = floor((scrollView.contentOffset.x - scrollView.frame.size.width / ) /  scrollView.frame.size.width) + ;
    imageNumLabel.text = [NSString stringWithFormat:@"%d/6",currentPage + ];
    //imageScroll.transform = CGAffineTransformMakeScale(1,1);
    if (currentPage==) {
        [scrollView setContentOffset:CGPointMake(, ) animated:NO];
        imageNumLabel.text = [NSString stringWithFormat:@"%d/6",];
    }
}
