Question 1

How do I migrate an existing UITableView to CascadingTableDelegate?

Accepted Answer

Start by creating a CascadingRootTableDelegate as your main delegate, then break down your existing delegate methods into child CascadingSectionTableDelegate instances for each section. Use the familiar UITableView APIs to refactor gradually, ensuring to handle unpropagated methods manually.

Question 2

CascadingTableDelegate vs using multiple view controllers for table sections: which is better?

Accepted Answer

CascadingTableDelegate is more lightweight and integrated, as it keeps logic within a single table view hierarchy without the overhead of separate view controllers. However, for highly independent sections with distinct navigation or state, view controllers might be more appropriate.

Question 3

Does CascadingTableDelegate support dynamic cell heights with autolayout?

Accepted Answer

Yes, it supports dynamic heights, but you need to implement height estimation methods carefully to avoid performance issues. The library propagates these calls, but default behaviors might require manual overrides for optimal rendering.

Question 4

What are common pitfalls when implementing CascadingTableDelegate?

Accepted Answer

Common issues include forgetting to add the 'weak' modifier to parentDelegate, leading to retain cycles, and not implementing unpropagated UITableViewDelegate methods for features like section index titles. Also, mismanaging estimated heights can cause layout breaks.

Question 5

Can I use CascadingTableDelegate with UICollectionView?

Accepted Answer

No, CascadingTableDelegate is specifically designed for UITableView and does not support UICollectionView. You would need a similar custom solution or a different library for collection view delegation.

Question 6

How does CascadingTableDelegate handle performance with large tables?

Accepted Answer

Performance is generally good due to modular delegation, but the added hierarchy layer can introduce slight overhead. For very large tables, ensure efficient cell reuse and consider implementing estimated height methods to avoid redundant calculations.
