you should use a TextInput
Component white the prop keyboardType = {"number-pad"}
import { TextInput } from "react-native";
then use it as
<TextInput
keyboardType = {"number-pad"}
// add more props ...
/>
for all the props you can add see this link
In the ipad it is showing alphabets also and we can able to enter those values also

Try replace
method in JS by replacing non alphabet character with empty string.
Code
import React, { Component } from 'react';
import { AppRegistry, TextInput } from 'react-native';
export default class UselessTextInput extends Component {
constructor(props) {
super(props);
this.state = { inputText: '' };
}
onChanged (text) {
this.setState({
inputText: text.replace(/[A-Za-z]/g, ''),
});
}
render() {
return (
<TextInput
style={{height: 40, borderColor: 'gray', borderWidth: 1, marginTop: 200}}
onChangeText={(text)=> this.onChanged(text)}
value={this.state.inputText}
/>
);
}
}
// skip this line if using Create React Native App
AppRegistry.registerComponent('AwesomeProject', () => UselessTextInput);

import { TextInput } from "react-native";
then use it as
<TextInput
keyboardType = {"number-pad"}
// add more props ...
/>
