ionic 3怎样更改页面push的速度？

Question

在官网看到NavController的这几个方法，但是不知道怎么用
animate boolean Whether or not the transition should animate.
animation string What kind of animation should be used.
direction string The conceptual direction the user is navigating. For example, is the user navigating forward, or back?
duration number The length in milliseconds the animation should take.
easing string The easing for the animation.

Answer 1

源码是这么写的

abstract push(page: Page | string, params?: any, opts?: NavOptions, done?: Function): Promise<any>;

其中NavOptions里面包含了

export interface NavOptions {
  animate?: boolean;
  animation?: string;
  direction?: string;
  duration?: number;
  easing?: string;
  id?: string;
  keyboardClose?: boolean;
  progressAnimation?: boolean;
  disableApp?: boolean;
  minClickBlockDuration?: number;
  ev?: any;
  updateUrl?: boolean;
  isNavRoot?: boolean;
}

你所要的速度就是direction
说了那么多，你要写的代码就是

constructor(public navCtrl: NavController) {}

push() {
    this.navCtrl.push(page, null, {
        direction: 0 // 毫秒
    });
}
