在app.ts ionic 2中对所有页面全局使用离子卷帘

import { Component, ViewChild } from '@angular/core';
import { Nav, Platform, Events } from 'ionic-angular';

@Component({
  templateUrl: 'app.html',
  providers: [/* 你的服务提供商 */]
  events: ['ionCurtain']
})

constructor(public platform: Platform, public events: Events) {
  // 其他初始化代码
}

this.platform.ready().then(() => {
  this.registerGlobalEvents();
});

registerGlobalEvents() {
  this.events.subscribe('ionCurtain', () => {
    // 执行卷帘操作
  });
}

import { Events } from 'ionic-angular';

constructor(public events: Events) {}

toggleCurtain() {
  this.events.publish('ionCurtain');
}
