Swift Collectionview从标签高度到单元格高度

我正在尝试创建一个集合视图，该视图可以从标签高度自动调整大小。我有两个不同的单元格，一个有照片，另一个没有照片，都在xib文件中

我尝试了不同的方法使这个高度动态化，但没有解决办法

您正在使用自动布局吗？您可以子类化

UICollectionViewCell

，并重写

intrinsicContentSize

——这可能会起到作用。此外，当我有需要动态调整大小的uiTextView时，我会使用以下代码段：

var CollectionViewCellNib = UINib(nibName: "CollectionViewCell", bundle: nil)
collectionView.registerNib(CollectionViewCellNib, forCellWithReuseIdentifier: "CollectionViewCell")
var CollectionViewCellWithPhotoNib = UINib(nibName: "CollectionViewCellWithPhoto", bundle: nil)
collectionView.registerNib(CollectionViewCellWithPhotoNib, forCellWithReuseIdentifier: "CollectionViewCell")

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
        let pikirler = self.pikirler[indexPath.row]
        let targetWidth: CGFloat = (self.collectionView.bounds.width - 2 * kHorizontalInsets)

        if indexPath.row == 2 {
            var cell = self.offscreenCells[CollectionViewKeyWords.collectionViewOnlyTextCell] as? CollectionViewCell
            if cell == nil {
                cell = NSBundle.mainBundle().loadNibNamed("CollectionViewCell", owner: self, options: nil)[0] as? CollectionViewCell

                self.offscreenCells[CollectionViewKeyWords.collectionViewOnlyTextCell] = cell
            }
            cell!.configCell("sometext", content: "sometext")
            cell!.bounds = CGRectMake(0, 0, targetWidth, cell!.bounds.height)
            cell!.contentView.bounds = cell!.bounds
            cell!.setNeedsLayout()
            cell!.layoutIfNeeded()
            var size = cell!.contentView.systemLayoutSizeFittingSize(UILayoutFittingCompressedSize)
            size.width = targetWidth

            return size
        }else{
            var cell = self.offscreenCells[CollectionViewKeyWords.collectioViewWithPhotoCell] as? CollectionViewCellWithPhoto
            if cell == nil {
                cell = NSBundle.mainBundle().loadNibNamed("CollectionViewCellWithPhoto", owner: self, options: nil)[0] as? CollectionViewCellWithPhoto

                self.offscreenCells[CollectionViewKeyWords.collectioViewWithPhotoCell] = cell
            }
            cell!.configCell("Some text", content: "sometext")
            cell!.bounds = CGRectMake(0, 0, targetWidth, cell!.bounds.height)
            cell!.contentView.bounds = cell!.bounds
            cell!.setNeedsLayout()
            cell!.layoutIfNeeded()

            var size = cell!.contentView.systemLayoutSizeFittingSize(UILayoutFittingCompressedSize)
            size.width = targetWidth

            return size

        }

    }
