HarmonyOS 鸿蒙Next ArkTS有iOS平台界面的viewWillAppear和viewWillDisappear生命周期方法吗？

看下 onPageShow onPageHide是不是您想要的https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/ts-custom-component-lifecycle-V5#onpageshow 看下无感监听 如:tabContentUpdate https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-arkui-observer-V5#observerontabcontentupdate12

import { uiObserver as observer, UIObserver } from '@kit.ArkUI';
@Component
export struct PagesComponent2 {
  uiObserver: UIObserver = this.getUIContext().getUIObserver();
  listener(info: observer.TabContentInfo) {
    if (info.state === observer.TabContentState.ON_SHOW) {
      console.log('TAG== PagesComponent2 == onPageShow');
    } else if (info.state === observer.TabContentState.ON_HIDE) {
      console.log('TAG== PagesComponent2 == onPageHide');
    }
  }
  aboutToAppear(): void {
    this.uiObserver.on('tabContentUpdate', this.listener.bind(this));
  }
  aboutToDisappear(): void {
    this.uiObserver.off('tabContentUpdate', this.listener.bind(this));
  }
  onPageShow(): void {
    console.log('PagesComponent2 onPageShow')
  }
  onPageHide(): void {
    console.log('PagesComponent2 onPageHide')
  }
  build() {
    Column(){
      Text('PagesComponent2').backgroundColor(Color.Gray)
    }
    .width('100%')
    .height('100%')
  }
}
