将uilabel/uiimageView添加到uicontentviewcell扰乱它的大小

我有一个在故事板上定义的UicollectionViewCell，它在其contentview中添加了Uilabel。收集视图使用流程布局，我在Flowlayout委托中返回一个固定的单元格大小，如下所示：

 let sizeOfItem = CGFloat(210.0)

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
   
    return CGSize(width: sizeOfItem, height: sizeOfItem)
}

我在故事板中添加了Uilabel的以下约束，并且该单元格自动开始调整大小以匹配Uilabel中的文本大小。这不是我想要的。我希望该单元格是固定的，并标记为AutoShrink。

我什至尝试将标签的ContentHuggingPriority设置为最低值（即1）。如果标签中的文本很小，这会阻止单元自动缩短。但是，当文本很大时，细胞仍然会生长。我也不希望这种情况发生。我希望该单元格的尺寸固定，并由代表中的SizeForitem返回，并将标签调整为字体大小。

编辑：我还将contentCompressionProperty设置为最低，然后可以工作。但是，我想知道解决此类方案的正确方法是什么，其中contentview不取决于子视图。

编辑2：当contentView中具有UIImageView时，问题也出现，并且图像比定义的单元格大小更大或更小。设置UIImageView的内在内容大小无济于事。

原文

I have a UICollectionViewCell defined in storyboard which has a UILabel added to it's contentView. Collection view uses a flow layout and I return a fixed size of cell in flowlayout delegate as follows:

 let sizeOfItem = CGFloat(210.0)

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
   
    return CGSize(width: sizeOfItem, height: sizeOfItem)
}

I added the following constraint for UILabel in storyboard and the cell automatically starts resizing itself to match the text size in UILabel. This is not what I want. I want the cell to be fixed size and label to autoshrink instead.

I even tried setting contentHuggingPriority of label to lowest value (i.e. 1). This stops the cell from auto-shrinking if the text in label is small. But still the cell grows when the text is big. I don't want this to happen either. I want the cell to be fixed size as returned by sizeForItem in delegate and the label to adapt it's font size.

EDIT: I also set contentCompressionProperty to lowest and it then works. But I am wondering what is the right way to fix this kind of scenario where contentView does not depend on subviews.

EDIT 2: The problem also appears when having UIImageView in contentView and the image is bigger or smaller than defined cell size. Setting intrinsic content size of UIImageView does not help.
