tableview顶部视图无限自动滚动 下拉可放大
ViewController中
- (void)viewDidLoad { [super viewDidLoad]; [self.view addSubview:self.tableView]; NSString *imageStr = @'图片1,图片2,图片3'; //banner设置图片源 [self.bannerView setBannerImageArray:imageStr]; } -(void)scrollViewDidScroll:(UIScrollView *)scrollView{ if (scrollView == _tableView) { CGPoint offset = scrollView.contentOffset; //下拉放大实现 if (offset.y < 0) { [self.bannerView setOffSetY:offset.y]; }else{ [self.bannerView setOffSetY:0]; } } }//bannerView中的实现
-(void)setOffSetY:(CGFloat)offSetY{ if (offSetY == 0) { [_timer setFireDate:[NSDate dateWithTimeIntervalSinceNow:4.0]]; }else{ [_timer setFireDate:[NSDate distantFuture]]; } CGFloat X = _index * offSetY; CGFloat Y = offSetY; CGFloat W = self.frame.size.width - offSetY; CGFloat H = self.frame.size.height - offSetY; _headerView.frame = CGRectMake(0, Y / 2, W, H); if (_imageUrlArray.count > 1) { NSInteger nextIndex = _pageCtrl.currentPage + 2; if (nextIndex == _imageUrlArray.count) { nextIndex = 2; } _bannerScrollView.bounds = CGRectMake((nextIndex - 1) * W, 0, W, H); _pageCtrl.currentPage = _index; }else{ _bannerScrollView.bounds = CGRectMake(0, 0, W, H); } }具体代码请下载附件查看
