Summary:
This bug was causing a redbox when touching rapidly because multiple touches had the same identifier. This code was meant to ensure that a unique ID is found, but it was checking against the wrong property in the react touch array.
I don't think this was really affecting prod, because the invariant is guarded by a __DEV__ check
@public
Test Plan:
- Start several touches at once (or just rapidly jam fingers on your device), and you won't see a redbox
- Also verify that single touches, touch moves, and multi touches work as before
Summary:
These two arrays aren't used. The code is easier to read without them
@public
Test Plan: Tap around UIExplorer and verify multi-touch and responder system behavior works the same
Summary:
Apparently British spelling is "cancelled", American is "canceled"? Picking "cancelled" for consistency with UIKit.
@public
Test Plan: landcastle
Summary:
When touches end or cancel, update self.state in
RCTTouchHandler to let iOS know that we are in an ended/canceled state.
This way we won't eat other touches because it still thinks we're in a
began/changed state.
@public
Test Plan:
Scrolling in the back swipe area no longer busts gesture
recognition in Wilde.
