苹果官方文档:Optimizing ProMotion Refresh Rates for iPhone 13 Pro and iPad Pro
Enable Faster ProMotion Refresh Rates
If you don’t enable faster refresh rates for your app, your CADisplayLink
callback might run at any of the speeds that the ProMotion display supports, at different times during normal GUI operations. In these cases, other animations in the system may affect the rate at which Core Animation calls your CADisplayLink
callback. The rate at which Core Animation calls your CADisplayLink
callback may not match the refresh rate hints that you provide to your CADisplayLink
callback. Specifically, Core Animation won’t unlock any refresh rate that’s faster than the system’s default.
On iPhone 13 Pro or iPhone 13 Pro Max, add the following key to your Info.plist
file to enable the full range of refresh rates for CADisplayLink
callbacks and CAAnimation
animations in your app:
<key>CADisableMinimumFrameDurationOnPhone</key><true/>
Your app must use this key to access higher frame rates (above 60Hz) it sets in the preferredFrameRateRange
hint API. The iPad Pro doesn’t require this special configuration.
