How can you dynamically determine the height of each cell in an interface?

In iOS, to dynamically determine the height of a cell in a table (UITableView) or collection (UICollectionView), you can use automatic height calculation based on the content.

For UITableView:

• Set the property tableView.rowHeight = UITableView.automaticDimension
• Set tableView.estimatedRowHeight to an approximate value
• Configure constraints within the cell so that Auto Layout can calculate the height

Example in Swift:

tableView.rowHeight = UITableView.automaticDimension
tableView.estimatedRowHeight = 100

For UICollectionView, you can use UICollectionViewFlowLayout with estimatedItemSize or create a custom layout.

Thus, the cell height will be calculated automatically depending on the content and Auto Layout constraints.
