ReactNative中实现确认码组件示例详解

<View style={[styles.container]}>
  <TextInput autoFocus={true} />
  <View
    style={[styles.cover, StyleSheet.absoluteFillObject]}
    pointerEvents="none">
    {cells.map((value: string, index: number) => (
      <View style={[styles.cell]}>
        <Text style={styles.text}>{value}</Text>
      </View>
    ))}
  </View>
</View>

const { onLayout, height } = useLayout()
const size = height
return (
  <View style={[styles.container, style]} onLayout={onLayout}>
    <TextInput />
    <View style={[styles.cover, StyleSheet.absoluteFillObject]}>
      {cells.map((value: string, index: number) => (
        <View
          style={[
            styles.cell,
            { width: size, height: size, marginLeft: index === 0 ? 0 : spacing }
          ]}>
          <Text style={styles.text}>{value}</Text>
        </View>
      ))}
    </View>
  </View>
)

export default function CodeInput({ value, length = 4 }) {
  const cells = value.split('').concat(Array(length - value.length).fill(''))
}
