Ionic 4:硬件返回按钮重新加载应用程序 [英] Ionic 4: Hardware Back Button Reloading Application

问题描述

正在处理一个项目并陷入问题:

Working on a Project and stuck in an Issue:

硬件后退按钮重新加载应用程序(我在此应用程序中使用 Angular Router).

Hardware Back Button Reloading Application (I am using Angular Router in this application).

我的退出应用程序代码:

My Code to Exit Application:

  ionViewDidEnter(){
      this.subscription = this.platform.backButton.subscribe(()=>{
          navigator['app'].exitApp();
      });
  }

  ionViewWillLeave(){
        this.subscription.unsubscribe();
  }

虽然相同的逻辑在其他应用程序中工作.但在这个应用程序中，它重新加载了应用程序而不是退出它.

While same logic Working in other applications. but in this application its reloading the application not exiting it.

P.S:我也试过把它放入 platform.ready() 但没有运气.

P.S: i have also tried it to put in platform.ready() but no luck.

推荐答案

已解决:

正如 @rtpHarry 模板的 SideMenu/Tabs 所提到的那样，它具有导致应用程序在根页面上自行重新加载的历史记录.我能够通过清除历史记录来解决这个问题.

As Mention by @rtpHarry template of SideMenu / Tabs have History which leads application to Reload it self on root page. i was able to solve this by clearing History.

ionViewDidEnter(){
  navigator['app'].clearHistory();    
}

在您的根页面上只需清除您的历史记录，您的硬件后退按钮将关闭应用程序而不是重新加载它.

on Your Root Page just Clear your history and your Hardware Back Button will close the Application instead of Reloading it.
