Fired before entering into a view, allows you to control whether the view can be accessed or not (returning true or false).

ionViewCanEnter(){
   console.log("ionViewCanEnter HomePage.");
}

ionViewCanLeave(){
  console.log('ionViewCanLeave SecondPage.');
}

Fired only when a view is stored in memory. This event is NOT fired on entering a view that is already cached. It’s a nice place for init related tasks.

ionViewDidLoad(){
 console.log("ionViewDidLoad HomePage.");
}

It’s fired when entering a page, before it becomes the active one. Use it for tasks you want to do every time you enter in the view (setting event listeners, updating a table, etc.).

  console.log('ionViewWillEnter HomePage.');
}

Fired when entering a page, after it becomes the active page. Quite similar to the previous one.

ionViewDidEnter(){
  console.log('ionViewDidEnter HomePage.');
}

Fired when you leave a page, before it stops being the active one. Use it for things you need to run every time you are leaving a page (deactivate event listeners, etc.).

ionViewWillLeave(){
    console.log('ionViewWillLeave HomePage.');
}

Fired when you leave a page, after it stops being the active one. Similar to the previous one.

ionViewDidLeave(){
  console.log('ionViewDidLeave HomePage.');
}

Fired when a view is going to be completely removed (after leaving a non-cached view).

ionViewWillUnload(){
