I am trying to animate up some views so that they are blocked by the giant keyboard in landscape. It works well if I simply animate the frames, but others have suggested that this is counter-productive and I should be updating the NSLayoutConstraints instead. However, they don’t seem to be animatable. Has anyone gotten them to work with success?
//heightFromTop is an NSLayoutConstraint referenced from IB
[UIView animateWithDuration:0.25 animations:^{
self.heightFromTop.constant= 550.f;
}];
The result is an instant jump to the height in question.
