一起水平滚动UICollectionView的所有行
我有UITableView 。 在UITableViewCell里面我已经放置了UICollectionView 。 目前所有的行都单独滚动。 我需要的是当用户以水平方式（从左到右或从右到左）滚动任何行时，所有的行必须以相同的模式滚动。
我已经按照下面的链接，但没有成功
用一个collectionview IOS滚动多个UICollectionView
手动滚动显示相同内容的两个UICollectionViews
请看看我的代码
视图控制器

在tableview行中同步集合视图的水平滚动
提前致谢
假设你有两个收集意见。 你能做的是这样的。
// say cv0 and cv1 are outlets to two table views func scrollViewDidScroll(scrollView: UIScrollView) { if scrollView == self.cv0 { self.cv1.contentOffset = self.cv0.contentOffset } else { if scrollView == self.tv1 { self.cv0.contentOffset = self.cv1.contentOffset } } }
如果你想要更多的集合视图，你可以编写一个通用的方法来处理它。 您可以将scrollView传递给此方法，并且相应地设置堆栈contentOffSet中的所有其他滚动视图。
感谢@Impossible现已解决的帮助问题。
首先，我在UITableView cellForRowAtIndexPath中设置了标签cell?.collection.tag
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { var cell = tableView.dequeueReusableCellWithIdentifier("cell") as? CategoryRow if cell == nil { cell = CategoryRow(style:UITableViewCellStyle.Subtitle, reuseIdentifier:"cell") } else { } cell!.tag = indexPath.section cell?.collection.tag = (100 * indexPath.section) + 1 cell?.collection.reloadData() cell?.collection.delegate = self return cell! }
然后我通过在scrollViewDidScroll里面使用标签方法viewWithTag来获得view
func scrollViewDidScroll(scrollView: UIScrollView) { for var i = 0 ; i < 8 ; i++ { let cell2 = self.view .viewWithTag((100 * i) + 1) as? UICollectionView if cell2 != nil { cell2!.contentOffset = scrollView.contentOffset } } }
