问题描述

我有一个显示照片的 UICollectionView.我已经使用 UICollectionViewFlowLayout 创建了集合视图.它工作得很好，但我想在边距上有间距.是否可以使用 UICollectionViewFlowLayout 或我必须实现自己的 UICollectionViewLayout 来做到这一点?

I have a UICollectionView which shows photos. I have created the collectionview using UICollectionViewFlowLayout. It works good but I would like to have spacing on margins. Is it possible to do that using UICollectionViewFlowLayout or must I implement my own UICollectionViewLayout?

推荐答案

您可以为您的 UICollectionView 使用 collectionView:layout:insetForSectionAtIndex: 方法或设置 附加到 UICollectionView 的 UICollectionViewFlowLayout 对象的 >sectionInset 属性:

You can use the collectionView:layout:insetForSectionAtIndex: method for your UICollectionView or set the sectionInset property of the UICollectionViewFlowLayout object attached to your UICollectionView:

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section{
    return UIEdgeInsetsMake(top, left, bottom, right);
}

或

UICollectionViewFlowLayout *aFlowLayout = [[UICollectionViewFlowLayout alloc] init];
[aFlowLayout setSectionInset:UIEdgeInsetsMake(top, left, bottom, right)];

为 Swift 5

更新

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {
       return UIEdgeInsets(top: 25, left: 15, bottom: 0, right: 5)
    }
