UICollectionViewCell поведение

Question

Я пытаюсь реализовать UICollectionView в моем UIViewController.Я использую файл Xib для UICollectionView и другой Xib для UICollectionViewCell.Я пытаюсь получить размер ячейки в соответствии с размером представления коллекции.

Моя проблема заключается в том, что когда я увеличиваю высоту представления коллекции, ячейка работает неправильно.

Неожиданное поведение

Высота по умолчанию

Код ячейки

class CollectionViewCell: UICollectionViewCell {
@IBOutlet weak var backView: UIView!
@IBOutlet weak var lineView: UIView!
@IBOutlet weak var dayLabel: UILabel!
@IBOutlet weak var lineLeftView: UIView!
@IBOutlet weak var lineRightView: UIView!
@IBOutlet weak var lineRightViewFull: UIView!
@IBOutlet weak var lineLeftViewFull: UIView!

let grayColor = UIColor(red: CGFloat(33/255), green: CGFloat(33/255), blue: CGFloat(33/255), alpha: 0.1)
let grayColor_bottomLine = UIColor(red: CGFloat(188/255), green: CGFloat(188/255), blue: CGFloat(188/255), alpha: 1)


override init(frame: CGRect) {
    super.init(frame: frame)
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
}

func design() {        
    let rectShape : CAShapeLayer  = CAShapeLayer()
    rectShape.bounds = backView.frame
    rectShape.position = backView.center
    rectShape.path = UIBezierPath(roundedRect: backView.bounds, byRoundingCorners: [.topLeft , .topRight], cornerRadii: CGSize(width: 20, height: 20)).cgPath
    backView.layer.mask = rectShape

    backView.backgroundColor = grayColor
    dayLabel.textColor = grayColor
    lineRightView.backgroundColor = grayColor
    lineLeftView.backgroundColor = grayColor
    lineView.backgroundColor = grayColor

    lineRightView.isHidden = true
    lineLeftView.isHidden = true
    lineRightViewFull.isHidden = true
    lineLeftViewFull.isHidden = true
}

func dataEntry(data : CollectionViewCellData) {
    dayLabel.text = data.day
    if data.IsItFirstDay {
        lineLeftView.isHidden = false
    }

    if data.IsItWeekEnd {
        lineRightView.isHidden = false
    }
}
