Early last year I mentioned a library providing a drop in replacement UITableViewCell or UICollectionViewCell that improved the performance when drawing static cells by using CoreGraphics called WCFastCell.

Here’s an open source library submitted by Danil Gontovnik that allows you to improve performance with dynamic table view and UICollectionView cells by pre-calculating the size of a text layout.

An example is included showing how to use DGDrawingLabel to create a high scrolling performance table view with dynamic cells.

You can find DGDrawingLabel on Github here.

A nice library for easily improving performance when scrolling.
