ios - 以编程方式快速增加内容视图的宽度

Question

如何增加内容​​视图的宽度，在元素之间添加一些空间边距并平均分布。下面是我尝试过的快速代码。

    class EatTypeCell : UICollectionViewCell{
        @IBOutlet weak var lblTitle: UILabel!
        override func awakeFromNib() {
            self.contentView.applyViewStyle(isRound: true, borderColor: UIColor.ColorGray, borderWidth: 1.5, backGroundColor: UIColor.ColorWhite)
            self.lblTitle.applyStyle(labelFont: UIFont.applySemiBold(fontSize: 11.5), textColor: UIColor.ColorGray)     
        } 
    }
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        let height = collectionView.frame.height/2 - 14
        var width : CGFloat = 0
        if self.colEat == collectionView {
        width = self.arrayMeal[indexPath.row].name.sizeOfString(font: UIFont.applySemiBold(fontSize: 11.5)).width + 50
        } 
        return CGSize(width: width, height: height)
    }
