How to change styling of TextInput placeholder in React Native?

Is there a way to set fontStyle: 'italic' only for the placeholder of the TextInput in React Native?

looking here at the documentation seems like you can only set a placeholder and placeholderTextColor.

You can set your placeholder color by using the placeholderTextColor prop.

<TextInput placeholderTextColor={'red'} />

Improving on Daniel's answer for a more generic solution

class TextInput2 extends Component {
  constructor(props) {
    super(props);
    this.state = { placeholder: props.value.length == 0 }
    this.handleChange = this.handleChange.bind(this);
  }
  handleChange(ev) {
    this.setState({ placeholder: ev.nativeEvent.text.length == 0 }); 
    this.props.onChange && this.props.onChange(ev); 
  }
  render() {
    const { placeholderStyle, style, onChange, ...rest } = this.props;

    return <TextInput 
      {...rest} 
      onChange={this.handleChange}
      style={this.state.placeholder ? [style, placeholderStyle] : style}
      />
  }
}

Usage:

<TextInput2 
  value={this.state.myText}
  style={{ fontFamily: "MyFont" }}
  placeholderStyle={{ fontFamily: "AnotherFont", borderColor: 'red' }}
/>
