Description
Description
<-- A clear and concise description of what the problem is. -->
When I was testing my app on iOS, then play/pause button that triggers the animation to restart isn't restarting, it just stays on the paused state once I press it to pause.
Provide a Repro
const riveRef = useRef<RiveRef>(null);
function onPressPause() {
setTimer(TimerState.Paused);
riveRef.current?.pause();
}
function onPressPlay() {
setTimer(TimerState.Running);
riveRef.current?.play();
}
return (
<>
<Rive
fit={Fit.Cover}
ref={riveRef}
url={RIVE_ASSET_URL}
artboardName={`AT_${animalType.toUpperCase()}`}
stateMachineName={INITIAL_STATE_MACHINE}
style={{ width: "100%", height: "100%" }}
autoplay
onPlay={(animationName, isStateMachine) => {
console.log(
"onPlay: ",
animationName,
"isStateMachine: ",
isStateMachine
);
}}
onPause={(animationName, isStateMachine) => {
console.log(
"onPause:",
animationName,
"isStateMachine: ",
isStateMachine
);
}}
onError={(riveError: RNRiveError) => {
console.error({ riveError });
}}
/>
{timer === TimerState.Paused ? (
<TimerButton
onPress={onPressPlay}
title="Resume"
accessibilityLabel="Resume timer"
icon={<PlayIcon />}
/>
) : (
<TimerButton
onPress={onPressPause}
title="Pause"
accessibilityLabel="Pause the timer"
icon={<PauseIcon />}
isDisabled={timer === TimerState.Finished}
/>
)}
</>
)
Expected behavior
The animation should start playing again once I evoke the .play() method.

Additional context
On Android, this works as expected.

Research direction
Start with the TypeScript reproduction's Rive ref calls to compare .pause() and .play() behavior on iOS versus Android. Trace the Rive component and playback entry points, then verify that invoking .play() after .pause() resumes the animation and preserves the expected callbacks.
