如何在UICollectionViewCell的

UICollectionView

然而,我试图通过使用 view.frame.width 细胞的宽度,但不幸的是我好像做错了什么。

UIViewController

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {

    let cellWidth : CGFloat = 110.0
    //let screenWidth = screenSize.width

    let numberOfCells = floor(self.view.frame.size.width / cellWidth)
    let edgeInsets = (self.view.frame.size.width - (numberOfCells * cellWidth)) / (numberOfCells + 1)

    return UIEdgeInsetsMake(20, edgeInsets, 0, edgeInsets)
}
