Re: Animating autolayout constraint changes for subviews

Sorry, I mostly copied your code and moved things around. Try -setNeedsLayout instead of -layoutIfNeeded. > On Dec 28, 2016, at 9:58 PM, Doug Hill wrote: > > Hello Steve, > > FWIW, I’ve tried both ways and it doesn’t seem to affect the problem I’m > having. However,

Re: Animating autolayout constraint changes for subviews

Hello Steve, FWIW, I’ve tried both ways and it doesn’t seem to affect the problem I’m having. However, Apple says to update constraints than do the animation block with layoutIfNeeded, according to this WWDC session: https://developer.apple.com/videos/play/wwdc2012/228/?id=228

Re: Animating autolayout constraint changes for subviews

I have always put the thing that I'm animating into the animation block: - (IBAction)animateIt:(id)sender { static BOOL small = NO; small = !small; CGFloat newWidth = small ? self.view.frame.size.width / 2 : self.view.frame.size.width; [UIView

Re: Animating autolayout constraint changes for subviews

Hi Ken, I uploaded a sample project here: https://github.com/djfitz/TestAutolayoutAnimations I tried to strip this down to what is needed to show the behavior I see. My code to actually do the animation is this: - (IBAction)animateIt:(id)sender { static BOOL small = NO; if(

Animating autolayout constraint changes for subviews

I had a previous question to the list about animating autolayout constraint changes at runtime. The documentation on this is a little thin and was grateful for the list's suggestions on the correct way to do this. I can now animate my constraint changes but I notice that subviews aren't
