[TextInput] lineheight cuts off content on iOS

[TLaMars]

Description

The TextInput on iOS cuts off content at dashes (-) if it has the lineHeight style applied to it. This happens when content is to long and therefore isn't completely visible in the input without moving through it.

If the lineHeight isn't applied it is not cut off at the dash (-) and the content will end with ellipsis (...).

We tried removing everything from the input and found out in that way it was the lineHeight that causes this issue.

This only happens on iOS and not on Android.

Steps to reproduce

It is reproducible by making an TextInput with just lineHeight on it with the styling.
Than as value pass a really long string or type a really long string with dashes.
Get out of focus with the input and see that the value in the input gets truncated.

import { TextInput, SafeAreaView, StyleSheet } from 'react-native';

export default function App() {
  const value = "Thisisareallylong emailwithdashes-init@thawdisisasnackwhichisanexample.com"

  return (
    <SafeAreaView style={styles.container}>
      <TextInput value={value} style={{ lineHeight: 20 }} />
    </SafeAreaView>
  );
}

@frankcalise , Did you find any solution? I am also facing the same issue.

[ctx-akumar-akumarclick]

My issue was happening due to textAlign: 'center' . I was able to resolve it with a this little hack.

[abhinandhand]

When line height is given I do face this same issue on iOS.

This issue still persists in 2026. Does anyone have a fix for it yet?
