有没有办法设置fontStyle：’italic’仅为React Native中的TextInput的占位符？
看起来像here at the documentation似乎只能设置一个占位符和placeholderTextColor.
解决方法
改进丹尼尔的一个更通用的解决方案的答案
class TextInput2 extends Component {
constructor(props) {
super(props);
this.state = { placeholder: props.text.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}
/>
}
}
用法：
<TextInput2
text={this.state.myText}
style={{ fontFamily: "MyFont" }}
placeholderStyle={{ fontFamily: "AnotherFont",borderColor: 'red' }}
/>
