UICollectionViewFlowLayout minimumInteritemSpacing不起作用 [英] UICollectionViewFlowLayout minimumInteritemSpacing doesn't work

问题描述

我的UICollectionView有两个问题:

I've got two problems with my UICollectionView:

• minimumInteritemSpacing不起作用
• 它在iOS 6上水平溢出

• minimumInteritemSpacing doesn't work
• it overflows horizontally on iOS 6

我这样设置布局:

UICollectionViewFlowLayout *layout = [[UICollectionViewFlowLayout alloc] init];
layout.itemSize = CGSizeMake(70.0f, 70.0f);
layout.scrollDirection = UICollectionViewScrollDirectionVertical;
layout.minimumLineSpacing = 0.0f;
layout.minimumInteritemSpacing = 0.0f;

_collectionView = [[UICollectionView alloc] initWithFrame:CGRectZero collectionViewLayout:layout];
// I set the size of _collectionView in layoutSubviews:
// _collectionView.frame = self.bounds;

_collectionView.contentInset = UIEdgeInsetsMake(8.0f, 8.0f, 8.0f, 8.0f);

该图显示了在iOS 6上的结果(在iOS 7上没有溢出，但是列之间的间距仍然不为零)

The image shows the result on iOS 6 (on iOS 7 there is no overflow, but the spacing between columns is still not zero)

我尝试了此解决方案 https://gist.github.com/OliverLetterer/5583087 ，但这并不能解决我的情况.

推荐答案

来自minimumInterItemSpacing属性的文档:

对于水平滚动网格，此值表示同一列中项目之间的最小间距.该间距用于计算一行中可以容纳多少个物品，但是确定了物品数量后，实际间距可能会向上调整.

流布局将在整个宽度上均匀分布单元格，其间距不小于，小于您设置的最小值.如果您不希望有间距，则需要实现自己的布局.

The flow layout will evenly space cells across its width, with a spacing of no smaller than the minimum you set. If you don't want the spacing, you'll need to implement your own layout.

我不确定iOS 6溢出问题.尝试放弃对iOS 6的支持；)

The iOS 6 overflow issue I'm not sure about. Try dropping support for iOS 6 ;)
