即使 UICollectionView 未满，也可滚动 [英] Make the UICollectionView scrollable even when its not full

问题描述

当视图中没有足够的单元格时，UICollectionView 默认禁用滚动.发生这种情况时，我需要它在拉动时弹回原位.我知道一个 hack，我可以用空表填充 UICollectionView 以启用滚动，但我希望会有一个更流畅的示例，如

The UICollectionView disables scrolling by default when there is not enough cells in the view. When this occurs I need it to bounce back to position when pulled. Im am aware of a hack where I can fill the UICollectionView with empty tables to enable scrolling but I was hoping there would be a slightly more fluid example as

我不希望视图滚动，而是自动弹回其位置.这是因为我在下面实现的效果如下所示.

I don't want the view to scroll but instead to automatically bounce back to its position. This is because of the effect I have implemented below as can see below.

有没有办法简单地实现这一点，当 UICollectionView 中没有足够的单元格时，滚动被禁用.

Is there a way to achieve this simply, when there is not enough cells in the UICollectionView the scroll is disabled.

self.collectionView.alwaysBounceVertical = YES;
