问题描述

要在collectionView中仅显示两列，我正在使用这段代码

To show only two columns in a collectionView i am using this piece of code

    let layout = self.collectionView.collectionViewLayout as! UICollectionViewFlowLayout
    layout.sectionInset = UIEdgeInsetsMake(0, 0, 0, 0)
    layout.minimumInteritemSpacing = 4
    layout.itemSize = CGSize(width:(self.collectionView.frame.size.width - 10)/2,height: (self.collectionView.frame.size.height)/3)

推荐答案

将此代码添加到 viewDidLoad . 根据您的身高来改变身高.

add this code to viewDidLoad. change height according to you.

尝试一下！

if let layout = collectionView?.collectionViewLayout as? UICollectionViewFlowLayout{
        layout.minimumLineSpacing = 10
        layout.minimumInteritemSpacing = 10
        layout.sectionInset = UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 10)
        let size = CGSize(width:(collectionView!.bounds.width-30)/2, height: 250)
        layout.itemSize = size
}
