displayLink.preferredFrameRateRange.preferred is always 0, so I can only use minimum and maximum. Alternatively, can you tell me other ways to detect refresh rate switching (frame rate tier switching)?

Apple’s APIs may not meet all business needs. To fulfill my boss’s request for frame rate statistics, I explored alternative solutions. Testing showed that CADisplayLink.preferredFrameRateRange.minimum and .maximum change dynamically, which can indicate frame rate gear switching on iOS. On Android, system frame rate changes can be directly monitored. To ensure consistency across platforms, a unified technical solution is necessary.
