how to apply animations for different views sequentially?

Question

There are four views on which I need to apply animation. If an user tap button, the animation is that view1 should hide for 1 second, and then view2, then view3, then view4.

The problem is that how to apply animations in different views with sequence?

I need to use Core Animation to finish it.

Answer 1

Use the animateWithDuration:animations:completion: method where the completion block calls a method which runs the next animation (and similarly its completion block starts the next part of the chain).
