[iOS] Ripple effect
I often get asked how the ripple effect is done in MacG Mobile when the news get refreshed, and is it difficult to do ? Well since people don’t seem to be able to type iphone SDK ripple effect in Google, I will post the solution… and it’s really easy since it’s just a constant, but it’s not documented.
So basically when you want an animation in a view you do something like this :
[UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:view cache:NO]; [UIView commitAnimations];
And this will flip your view.
To make a ripple effect, you just have to pass 110 for the first parameter of
setAnimationTransition: and there it is, you have it.
If you pass 103 you will have the nice suck effect like in the Mail app when you delete a message.
