如何在指令中使用ionViewDidEnter

ng generate directive IonViewDidEnter

import { Directive, ElementRef, Renderer2, AfterViewInit, OnDestroy } from '@angular/core';
import { Platform } from '@ionic/angular';
import { Subscription } from 'rxjs';

@Directive({
  selector: '[appIonViewDidEnter]'
})
export class IonViewDidEnterDirective implements AfterViewInit, OnDestroy {
  private ionViewDidEnterSubscription: Subscription;

  constructor(
    private el: ElementRef,
    private renderer: Renderer2,
    private platform: Platform
  ) {}

  ngAfterViewInit() {
    // 等待平台准备好
    this.platform.ready().then(() => {
      // 监听 ionViewDidEnter 事件
      this.ionViewDidEnterSubscription = this.platform.resume.subscribe(() => {
        this.onIonViewDidEnter();
      });
    });
  }

  ngOnDestroy() {
    // 取消订阅
    if (this.ionViewDidEnterSubscription) {
      this.ionViewDidEnterSubscription.unsubscribe();
    }
  }

  private onIonViewDidEnter() {
    // 在视图完全进入时执行的操作
    console.log('ionViewDidEnter: View has fully entered');
    // 你可以在这里添加你的自定义逻辑
  }
}

<ion-content appIonViewDidEnter>
  <!-- 你的内容 -->
</ion-content>
