I have a custom iOS Picker Modal component and I want to add placeholder on it, is there anyway to do that? And my pickers are generated by map function, here is my picker code
class PickerWrapper extends React.Component {
constructor(props) {
super(props);
this.state = {
type_absen: '',
modal: false
}
}
render() {
let picker;
let iosPickerModal = (
<Modal isVisible={this.state.modal} hideModalContentWhileAnimating={true} backdropColor={color.white} backdropOpacity={0.9} animationIn="zoomInDown" animationOut="zoomOutUp" animationInTiming={200} animationOutTiming={200} onBackButtonPress={() => this.setState({ modal: false })} onBackdropPress={() => this.setState({ modal: false })} ><View style={{ backgroundColor: color.white, width: 0.9 * windowWidth(), height: 0.3 * windowHeight(), justifyContent: 'center' }}><Picker
selectedValue={this.state.type_absen}
onValueChange={(itemValue, itemIndex) => {
this.setState({ type_absen: itemValue });
this.setState({ modal: false });
setTimeout(() => this.props.onSelect(itemValue), 1200);
}}>
{this.props.items.map((item, key) => <Picker.Item label={item.description} value={item.id} key={item.id} />)}</Picker></View></Modal>);
if (Platform.OS === 'ios') {
var idx = this.props.items.findIndex(item => item.id === this.state.type_absen);
return (<View style={this.props.style}>
{iosPickerModal}<TouchableOpacity onPress={() => this.setState({ modal: true })}><View style={{ flexDirection: 'row', height: this.props.height ? this.props.height : normalize(40), width: this.props.width ? this.props.width : 0.68 * windowWidth(), borderWidth: 1, borderColor: color.blue, alignItems: 'center', borderRadius: 5 }}><Text style={{ fontSize: fontSize.regular, marginRight: 30 }}> {idx !== -1 ? this.props.items[idx].description : this.state.type_absen}</Text><IconWrapper name='md-arrow-dropdown' type='ionicon' color={color.light_grey} size={20} onPress={() => this.setState({ modal: true })} style={{ position: 'absolute', right: 10 }} /></View></TouchableOpacity></View >);
}
}
