UITableView contentSize未更新

Question

I have the UITableView with UITableViewCell, which contains UICollectionView, as:

• UITableViewCell
• UITableViewCell
  • UICollectionViewCell
  • UICollectionViewCell

In UICollectionView data is adding dynamically. I have subscribed to UICollectionView contentSize and I am changing frame of UICollectionView accordingly to contentSize. It's working fine and frame of UITableViewCell containing UICollectionView is changing correctly, but UITableView contentSize does not updating. And I don't understand why?

UITableView items height is set to UITableViewAutomaticDimension

Answer 1

The best solution I've found. This is to do the calculation of height manually, without using UITableViewAutomaticDimension.

Yes, you have to spend a time for writing this.

After each added element of the UICollectionViewCell, you need to make an update your tableView (depending on what suits you):

• reloadRows(at:with:)
• reloadSections(_:with:)
• reloadData()
