如何在ionic 2中隐藏3秒后的图像？

<ion-img id="myImage" src="path/to/image.jpg"></ion-img>

import { Component, ViewChild, Renderer2 } from '@angular/core';

@Component({
  selector: 'app-my-component',
  templateUrl: 'my-component.html',
  styleUrls: ['my-component.scss'],
})
export class MyComponent {
  @ViewChild('myImage') myImage: any;

  constructor(private renderer: Renderer2) {}
}

ionViewDidEnter() {
  setTimeout(() => {
    this.renderer.setStyle(this.myImage.nativeElement, 'display', 'none');
  }, 3000);
}
