* | Page Event | Description |
* |---------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
* | `ionViewDidLoad` | Runs when the page has loaded. This event only happens once per page being created. If a page leaves but is cached, then this event will not fire again on a subsequent viewing. The `ionViewDidLoad` event is good place to put your setup code for the page. |
* | `ionViewWillEnter` | Runs when the page is about to enter and become the active page. |
* | `ionViewDidEnter` | Runs when the page has fully entered and is now the active page. This event will fire, whether it was the first load or a cached page. |
* | `ionViewWillLeave` | Runs when the page is about to leave and no longer be the active page. |
* | `ionViewDidLeave` | Runs when the page has finished leaving and is no longer the active page. |
* | `ionViewWillUnload` | Runs when the page is about to be destroyed and have its elements removed.
