描述

Odd bug, I'm getting this error after spamming the router forward and back.

2015-06-07 15:53:43.681 [error][tid:com.facebook.React.JavaScript] "Error: Touchable cannot transition from `RESPONDER_INACTIVE_PRESS_IN` to `LONG_PRESS_DETECTED` for responder `.r[1]{TOP_LEVEL}[0].0.0.0.1.1.0.0`

研究方向
The issue involves a crash when spamming forward/back navigation, resulting in an invalid state transition in Touchable. Investigate the touch responder logic in react native router, particularly the transition from RESPONDER INACTIVE PRESS IN to LONG PRESS DETECTED. Look at the source code for handling rapid navigation and see if there is a race condition or missing state cleanup. Consider reproducing with a minimal example and reviewing related issues or PRs.
