After iOS 9 huge CPU usage

Open ghost opened this issue 10 years ago • 2 comments

Hi, I'm using Mapbox in my app and after update to iOS 9 maps became very slow and irresponsive. On iPhone 6 with iOS 9 CPU usage is around 100% on one core, same app on iOS 8 and different iPhone 6 has ~2% CPU. I don't really know what to do with it custom map is one of the key feature of this app. Has anyone similar problem?

Hi @blazejchwiecko, can you try profiling your app in Instruments? Curious if anything stands out.

It's weird but didUpdateLocation uses almost all of my CPU, so I'm guessing is about redrawing annotations after location update.
