The Quest for 60FPS: Graphics Optimisation on iOS

Tim Oliver, Lateral Pty Ltd

Creating a very responsive UI is one of the hallmarks of a great app. But with so many generations of iOS devices out there, keeping an app running at 60 frames-per-second across the board can become a real challenge!

This talk covers a range of techniques that can be used to help speed up the responsiveness of you apps, from optimising view layout and draw times in low-latency tactile elements such as scroll views to setting up complex animations in Core Animation. It also covers methods for measuring your apps’ performance in Instruments to locate and weed out bottlenecks. Anything less than 60FPS is unacceptable!
