如何在ionic应用程序中显示可重复的metabox值

<ion-header>
  <ion-toolbar>
    <ion-title>
      Metabox Values
    </ion-title>
  </ion-toolbar>
</ion-header>

<ion-content>
  <ion-list>
    <ion-item *ngFor="let value of metaboxValues">
      {{ value }}
    </ion-item>
  </ion-list>
</ion-content>

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { Storage } from '@ionic/storage';

@Component({
  selector: 'page-metabox',
  templateUrl: 'metabox.html'
})
export class MetaboxPage {
  metaboxValues: any[];

  constructor(public navCtrl: NavController, public storage: Storage) {
    this.metaboxValues = [];
  }

  ionViewDidLoad() {
    this.storage.get('metaboxValues').then((values) => {
      if (values) {
        this.metaboxValues = values;
      }
    });
  }
}
