使用Angular关闭Modal - Ionic 4

import { ModalController } from '@ionic/angular';

constructor(private modalController: ModalController) {}

async openModal() {
  const modal = await this.modalController.create({
    component: MyModalComponent
  });
  await modal.present();
}

closeModal() {
  this.modalController.dismiss();
}

closeModal() {
  this.modalController.dismiss({
    data: 'Some data'
  });
}

async openModal() {
  const modal = await this.modalController.create({
    component: MyModalComponent
  });
  modal.onDidDismiss().then((data) => {
    console.log(data);
  });
  await modal.present();
}

closeModal() {
  this.modalController.dismiss({
    data: 'Some data'
  });
}

async openModal() {
  const modal = await this.modalController.create({
    component: MyModalComponent
  });
  modal.onWillDismiss().then((data) => {
    console.log(data);
  });
  await modal.present();
}
