Description

I have this issue that I can't seem to find anyone else talking about having the same problem. Basically, if you have the screen reader enabled on iOS and long scroll (so the tap tap tap happens), on an inaccessible container, then the screen reader ends up focusing on the container. Weirdly, the outline for the screen reader stays where you were. Scrolling backwards does go back up from the bottom through the elements.

I've started a basic React Native app and the same thing happens. In the attached videos, I scroll just enough to get the long horizontal tap scroll engaged, and then the screen reader loses focus and is focused on the bottom of the screen. I then swipe right, and it gives the sort of "end of page" sound even though visually, I'm on the first element still. I can then swipe left, and be back into the content but at the bottom of the page.

Any help would be amazing - is there just something I am missing about ensuring content is not accessible?

My modified and very bare bones App.tsx from the default new React Native app

function App(): JSX.Element {
  const isDarkMode = useColorScheme() === 'dark';

  const backgroundStyle = {
    backgroundColor: 'gray',
    flex: 1, // happens with or without the flex here
  };

  return (
    <SafeAreaView
      style={backgroundStyle}
      accessible={false}
      importantForAccessibility="no">
      <ScrollView
        contentInsetAdjustmentBehavior="automatic"
        style={backgroundStyle}
        accessible={false}
        importantForAccessibility="no"
        horizontal={false}>
        <Header />
        <View
          style={{
            backgroundColor: isDarkMode ? Colors.black : Colors.white,
          }}
          accessible={false}
          importantForAccessibility="no">
          <Section title="Step One">
            Edit <Text style={styles.highlight}>App.tsx</Text> to change this
            screen and then come back to see your edits.
          </Section>
        </View>
      </ScrollView>
    </SafeAreaView>
  );
}

Steps to reproduce
  1. Create a new React Native app npx react-native@latest init ScreenReaderTest
  2. Remove enough content from the body of App() so that the content doesn't reach the bottom of the screen
  3. Make everything inaccessible except for the Text elements
  4. Build the app to a physical iOS device
  5. Select the first Text element on the screen
  6. Engage the horizontal scroll slide gesture at the bottom of the screen, you should hear the multi tap sound
    • even a longer slide can engage it
  7. The screen reader outline will still be on the first element, but you can't swipe to the next element
  • You can however swipe backwards to move upwards on the page, as the focus is now at the bottom of the screen

Direzione di ricerca

Inizia con lo Snack collegato e la riproduzione minima in App.tsx, quindi eseguila su un dispositivo iOS fisico con VoiceOver e segui i passaggi elencati per lo scorrimento orizzontale. Confronta il focus di accessibilità con il contorno visibile prima e dopo il gesto; il lavoro è completato quando il comportamento del focus è stato corretto oppure quando la limitazione e la configurazione interessata sono documentate chiaramente.
