问题 I am having troubles with an autosizing UITableViewCell which contains a UICollectionView. The view hierarchy is roughly like this UITableViewCell -- Content View ---- Custom View ------ UIStackView (vertical) --------- UILabel --------- UICollectionView (vertical flow layout) When the UITableViewCell is created or reused, the collectionView receives a datasource which it then starts to process. I need all cells of the collectionView to show in the tableViewCell, so I observe changes to the
