ionic v2中新的周期函数

Page Event	Description
ionViewLoaded	Runs when the page has loaded. This event only happens once per page being created and added to the DOM. If a page leaves but is cached, then this event will not fire again on a subsequent viewing. The ionViewLoaded 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.
ionViewDidUnload	Runs after the page has been destroyed and its elements have been removed.
