Usage

Basic secure field

BasicSecureFieldExample.tsx

import { useState } from 'react';
import { Host, SecureField } from '@expo/ui/swift-ui';

export default function BasicSecureFieldExample() {
  const [password, setPassword] = useState('');

  return (
    <Host matchContents>
      <SecureField placeholder="Password" onTextChange={setPassword} />
    </Host>
  );
}

Submit handling

Use the submitLabel and onSubmit modifiers to handle form submission from the keyboard.

SecureFieldSubmitExample.tsx

import { useState } from 'react';
import { Host, SecureField } from '@expo/ui/swift-ui';
import { submitLabel, onSubmit } from '@expo/ui/swift-ui/modifiers';

export default function SecureFieldSubmitExample() {
  const [password, setPassword] = useState('');

  return (
    <Host matchContents>
      <SecureField
        placeholder="Password"
        onTextChange={setPassword}
        modifiers={[submitLabel('done'), onSubmit(() => console.log('Login submitted'))]}
      />
    </Host>
  );
}

Imperative ref

Use a ref to imperatively set text, focus, or blur the secure field.

ImperativeSecureFieldExample.tsx

import { useRef } from 'react';
import { Host, SecureField, SecureFieldRef, Button, HStack, VStack } from '@expo/ui/swift-ui';
import { buttonStyle } from '@expo/ui/swift-ui/modifiers';

export default function ImperativeSecureFieldExample() {
  const ref = useRef<SecureFieldRef>(null);

  return (
    <Host matchContents>
      <VStack>
        <SecureField ref={ref} placeholder="Password" />
        <HStack spacing={12}>
          <Button
            modifiers={[buttonStyle('bordered')]}
            onPress={() => ref.current?.focus()}
            label="Focus"
          />
          <Button
            modifiers={[buttonStyle('bordered')]}
            onPress={() => ref.current?.blur()}
            label="Blur"
          />
          <Button
            modifiers={[buttonStyle('bordered')]}
            onPress={() => ref.current?.setText('secret123')}
            label="Set Text"
          />
        </HStack>
      </VStack>
    </Host>
  );
}
