UICollectionView中的单元格间距 [英] Cell spacing in UICollectionView

问题描述

如何在 UICollectionView 的部分设置单元格间距？我知道有一个属性 minimumInteritemSpacing 我已经将它设置为5.0，但是间距没有出现5.0。我已经实现了flowout委托方法。

How do I set cell spacing in a section of UICollectionView? I know there is a property minimumInteritemSpacing I have set it to 5.0 still the spacing is not appearing 5.0. I have implemented the flowout delegate method.

- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section
{

    return 5.0;
}

仍然没有得到理想的结果。我认为它的最小间距。我有没有办法设置最大间距？

still I am not getting the desired result. I think its the minimum spacing . Isn't there any way by which I can set the maximum spacing?

推荐答案

我知道这个话题已经过时了，但万一有人还需要正确答案你需要什么：

I know that the topic is old, but in case anyone still needs correct answer here what you need:

1. 覆盖标准流程布局。



2. 添加如下实现：

1. Override standard flow layout.

2. Add implementation like that:

- (NSArray *) layoutAttributesForElementsInRect:(CGRect)rect {
    NSArray *answer = [super layoutAttributesForElementsInRect:rect];

    for(int i = 1; i < [answer count]; ++i) {
        UICollectionViewLayoutAttributes *currentLayoutAttributes = answer[i];
        UICollectionViewLayoutAttributes *prevLayoutAttributes = answer[i - 1];
        NSInteger maximumSpacing = 4;
        NSInteger origin = CGRectGetMaxX(prevLayoutAttributes.frame);

        if(origin + maximumSpacing + currentLayoutAttributes.frame.size.width < self.collectionViewContentSize.width) {
            CGRect frame = currentLayoutAttributes.frame;
            frame.origin.x = origin + maximumSpacing;
            currentLayoutAttributes.frame = frame;
        }
    }
    return answer;
}

其中maximumSpacing可能是设置为您喜欢的任何值。这个技巧保证了单元格之间的空间完全等于maximumSpacing !!

where maximumSpacing could be set to any value you prefer. This trick guarantees that the space between cells would be EXACTLY equal to maximumSpacing!!
