ionic+angular使用ion-popover之如何关闭popover

用componentProps把popover实例传过去即可

async presentPopover(ev: any) {
  const popover = await this.popoverController.create({
    component: PopoverComponent,
    cssClass: 'my-custom-class',
    event: ev,
    translucent: true,
    componentProps: this.popover
  });
  await popover.present();
  this.popover = popover;
}
