带有 UIScrollView 的 UICollectionViewCell 取消 didSelectItemAtIndexPath [英] UICollectionViewCell with UIScrollView cancels didSelectItemAtIndexPath

问题描述

我有一个 UICollectionView 水平滚动以一次显示一个 UICollectionViewCell.每个 UICollectionViewCell 都有一个垂直滚动的 UIScrollView 作为用于滚动单元格内容的子视图.UIScrollView 只覆盖了 UICollectionViewCell 内部的 90% 左右 - 即单元格的外框没有被它覆盖.>

结果是UIScrollView覆盖的UICollectionViewCell部分取消了UICollectionView委托didSelectItemAtIndexPath.因此，当在 UIScrollView 内发生简单的点击时，此方法不会被调用，而如果点击发生在单元格的外部，即在 UIScrollView，这个方法被调用.

关于如何实现可以调用 didSelectItemAtIndexPath 方法的设置的任何建议，即使点击发生在 UIScrollView 中?

解决方案

UIScrollView 上的点击用于查看是否应该进行滚动.

您应该抓住 UIScrollView 本身的单击 并传递它到周围的 UICollectionViewCell.

I have a UICollectionView that horizontally scrolls to show one UICollectionViewCell at a time. Each UICollectionViewCell the has a vertically scrolling UIScrollView as subview for scrolling the contents of the cell. It is only 90 % or so of the inner part of the UICollectionViewCell that is covered by the UIScrollView - i.e. the outer frame of the cell is not covered by this.

It turns out that the part of the UICollectionViewCell that is covered by the UIScrollViewcancels the UICollectionView delegate didSelectItemAtIndexPath. Thus when a simple tap happens within the UIScrollView this method is not invoked, whereas if the tap happens on the outer part of the cell, i.e. outside the UIScrollView, this method is invoked.

Any suggestions as to how to achieve a setup where it is possible to invoke the didSelectItemAtIndexPath method even when the tap happens within the UIScrollView?

解决方案

The tap on the UIScrollView is used to see whether scrolling should be done.

You should catch the single tap on the UIScrollView itself and pass it on to the surrounding UICollectionViewCell.
