Keeping UITableView’s scrolling fast can be especially difficult with images, and I’ve mentioned a few resources such as Haneke which allows for easy image caching.

Here’s an open source tool from Di Wu that makes it easier to optimize tableviews by allowing you to quickly find cells that take too long to render.

To use DWURecyclingALert you simply drop it into your app, and then you can see how long it takes to render each individual cell, and also marks anything created in the spot while the user is scrolling so you can see what needs caching.

Here’s an animation from the readme showing DWURecyclingAlert in action:

You can find DWURecyclingAlert on Github here.

A nice tool for optimizing UITableViews.
