Page events (show, hide)

[Stephane Bisson]

Hi, 

My app is a simple analog clock. It animates the second hand. How do I turn the animation on when the page is shown and off when it is not shown?

thanks, 

stephane

That depends :)

To me, animation management should be happening in the view, not the controller. This makes the job of detecting when you're on- and off-screen different for each platform. Have a look at:

For example, for web you should implement show() and hide() for your page objects. For iOS, you'll probably be implementing viewDisappeared. Or whatever it's called.
