If you want to animate the hidden
property of a view, or animate the title
of a button, the solution is simple - use UIView.transitionWithView(button [...]
. If you want to animate the title
of several buttons, the solution is just as simple - use UIView.transitionWithView(containerView [...]
.
The problem arises when you want to animate constraint changes at the same time: they won't be animated anymore, no matter if you encapsulate them in the same transitionWithView
call, a new one, or inside an animateWithDuration
call.
The only solution I found is to do a transitionWithView
call for each button that needs its title
changed, and animate the constraints as usual, inside an animateWithDuration
call.
These kind of changes can also be animated with a CABasicAnimation
/ CATransition
, and adding that animation to the view's layer
, but in case you need transitionWithView
, or don't know why your constraints aren't animating, this might be the reason.
