UICollectionView 不调用委托方法 [英] UICollectionView doesn't call delegate methods

问题描述

我在故事板中设置了一个 UICollectionView 并连接了数据源和委托插座.我已经通过 nib 注册了一个单元，我在 cellForItemAtIndexPath: 方法中出列.

I've setup a UICollectionView in a storyboard and connected the dataSource and delegate outlets. I've registered a cell via nib which I dequeue in the cellForItemAtIndexPath: method.

所有工作都完美地期望永远不会调用委托方法.例如:当触摸一个单元格时，我希望 didSelectItemAtIndexPath: 被调用.

All works perfectly expect that the delegate methods are never called. For example: When touching on a cell, I expect the didSelectItemAtIndexPath: to be called.

我已经仔细检查了集合视图的委托 - 它已正确分配.

I've double-checked the delegate of the collection view - it's assigned correctly.

有谁知道不调用方法的原因吗?

Does anybody know the reason why the methods are not called?

推荐答案

这完全是我的错.我在前面添加了一个透明的子视图，它消耗了触摸 - 一个非常严重的错误.

It's completely my fault. I've added a transparent subview to the front which consumes the touches - a really bad mistake.
