一起水平滚动UICollectionView的所有行
问题描述：
我有UITableView.在UITableViewCell内部，放置了UICollectionView.当前，所有行都单独滚动.我需要的是，当用户水平滚动任何行(从左到右或从右到左)时，所有行必须以相同的模式滚动.
I have UITableView. Inside UITableViewCell I have placed UICollectionView. Currently all the row scrolling individually. What I need is when User scroll any row in horizontally manner (left to right or right to left) all the row must be scroll on same pattern.

使用一个collectionview IOS滚动多个UICollectionView
请看一下我的代码

假设您有2个集合视图.您可以做的就是这样.
Say that you have 2 collection views. What you can do is something like this.
// 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
}
}
}
如果要获取更多集合视图，可以编写一个通用方法来处理它.您可以将scrollView传递给此方法，并相应地设置堆栈contentOffSet中的所有其他滚动视图.
If you want to it for more collection views you can write a generic method to handle it. You can pass scrollView to this method and all other scroll views in the stack contentOffSet is set accordingly.
