如何在ionic 2中对任意输入字段设置焦点？

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

@Component({
  selector: 'app-your-component',
  templateUrl: 'your-component.html',
  styleUrls: ['your-component.scss'],
})
export class YourComponent {
  @ViewChild('inputField') inputField: IonInput;

  // 其他代码...
}

<ion-input #inputField></ion-input>

setFocus() {
  this.inputField.setFocus();
}
