[iOS] Implement pressOutAfterAnimation on Touchable

[m-bert]

Description

iOS half of #4568. Inside ScrollView UIKit holds the touch for delaysContentTouches until it rules out a scroll, and a tap released within that window gets touchesBegan and touchesEnded delivered together, so onPressIn and onPressOut reach JS in one batch and feedback driven from them never shows.

With pressOutAfterAnimation, a press deferred that way holds onPressOut until the press-in animation (animationDuration) has played, the same moment the native press-out animation starts. onPress is not delayed. A press UIKit did not defer keeps its native timing; RN's own lists turn delaysContentTouches off, so they are unaffected.

Test plan

Tested on the following code:

import React, { useRef, useState } from 'react';
import { Animated, StyleSheet, Text, View } from 'react-native';
import { ScrollView, Touchable } from 'react-native-gesture-handler';

// `pressOutAfterAnimation` (#4515): both cards drive a custom scale animation from
// onPressIn/onPressOut, inside a scrolling container. Tap them as briefly as you can.
// "animated" counts the taps whose press-in animation ran to completion: Android presses
// a quick tap on the UP, so without the prop onPressOut cancels the animation right away;
// with the prop onPressOut waits until the press-in animation (animationDuration) has played.
// The hold is measured from the native press, and the JS animation starts a few ms later, so
// the press-in duration is given a margin over the JS animation to keep the counter exact.
const ANIMATION_MS = 80;
const PRESS_IN_MS = 120;

function AnimatedCard({ withProp }: { withProp: boolean }) {
  const [taps, setTaps] = useState(0);
  const [animated, setAnimated] = useState(0);
  const scale = useRef(new Animated.Value(1)).current;

  const animateTo = (value: number, onDone?: () => void) =>
    Animated.timing(scale, {
      toValue: value,
      duration: ANIMATION_MS,
      useNativeDriver: true,
    }).start(({ finished }) => finished && onDone?.());

  return (
    <Touchable
      animationDuration={{ in: PRESS_IN_MS, out: ANIMATION_MS }}
      pressOutAfterAnimation={withProp}
      onPressIn={() => animateTo(0.94, () => setAnimated((n) => n + 1))}
      onPressOut={() => animateTo(1)}
      onPress={() => setTaps((n) => n + 1)}>
      <Animated.View
        style={[
          styles.card,
          withProp ? styles.cardWithProp : styles.cardWithoutProp,
          { transform: [{ scale }] },
        ]}>
        <Text style={styles.cardTitle}>
          {withProp ? 'With the prop' : 'Without the prop'}
        </Text>
        <Text style={styles.cardSubtitle}>
          pressOutAfterAnimation={String(withProp)}
        </Text>
        <View style={styles.stats}>
          <Stat label="taps" value={taps} />
          <Stat label="animated" value={animated} />
        </View>
      </Animated.View>
    </Touchable>
  );
}

function Stat({ label, value }: { label: string; value: number }) {
  return (
    <View style={styles.stat}>
      <Text style={styles.statValue}>{value}</Text>
      <Text style={styles.statLabel}>{label}</Text>
    </View>
  );
}

export default function PressOutAfterAnimationExample() {
  return (
    <ScrollView style={styles.root} contentContainerStyle={styles.content}>
      <Text style={styles.hint}>
        Tap each card as briefly as you can. The card scales down from onPressIn
        and back from onPressOut; "animated" counts the taps whose press-in
        animation finished.
      </Text>
      <AnimatedCard withProp={false} />
      <AnimatedCard withProp />
    </ScrollView>
  );
}

📝 Summary

Summary by CodeRabbit

• New Features
  • Added an iOS option to synchronize button press-out feedback with the tap animation when a press is delayed by a scrolling container.
  • When enabled, press-out feedback waits for any remaining animation time. Presses without a delay, or after the animation has finished, still respond immediately.
  • If a pending press-out is followed by a new press or the pointer re-enters the button, the pending feedback completes before the next press-in feedback.

📝 Summary

Walkthrough

The iOS button adds the pressOutAfterAnimation property. When enabled for a press delayed by an ancestor scroll view, the button can defer PressOut until the press-in animation finishes. The component view forwards the property to the button.

Changes

iOS button press-out timing

Layer / File(s)	Summary
Property and deferred-press detection packages/react-native-gesture-handler/apple/RNGestureHandlerButton.h, packages/react-native-gesture-handler/apple/RNGestureHandlerButtonComponentView.mm, packages/react-native-gesture-handler/apple/RNGestureHandlerButton.mm	The button exposes pressOutAfterAnimation, and the component view passes its value to the button. The button records when a press occurs inside an ancestor scroll view with delaysContentTouches enabled.
PressOut scheduling and lifecycle packages/react-native-gesture-handler/apple/RNGestureHandlerButton.mm	Press-out paths use timing-aware dispatch. When the configured conditions apply, the button schedules PressOut for the remaining press-in animation time and retains any following InteractionFinished event. Re-entry or a new press flushes a pending event. Window removal flushes it, and recycling cancels it.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to e4eda

Brief taps may leave JS reporting a pressed state after native feedback has cleared under Reduce Motion or very short animation settings. The impact is bounded, but the timing should be checked before merging.
