回来时未调用ngOnInit [英] ngOnInit not called when coming back

问题描述

我注意到当我回到已经实例化的页面时，没有调用ngOnInit()方法.我必须使用其他任何方法吗?我需要一种在他访问特定页面时每次都会调用的方法.

I noticed that the ngOnInit() method gets not called when I come back to the page which is already instanced. I have to use any other method for this? I need a method which is called everytime when he is visiting the specific page.

编辑 已测试onPageWillEnter()，但在Ionic 2中未触发

EDIT Tested already onPageWillEnter() but it gets not fired in Ionic 2

推荐答案

检查生命周期事件部分.

您可以使用ionic 2生命周期挂钩

You can use ionic 2 lifecycle hook

ionViewWillEnter(){
 //your methods
}
