You could just create width constraints for your views in IB, and give your controller outlets to the constraints themselves. You could then adjust the constant property on the constraints in code. The documentation claims that this performs better than removing constraints and adding new ones.

Autolayout Freespace
Is there a way autolayout can be told to proportionally divide available free space amongst a set of views? For example (please ignore the actual 'VFL' and consider the following horizontal layout string as pseudo code): H:|-[FirstName]-[LastName]-[SocialSecurity]-[Birthday]-[Age]-| Assume that each control hugs its own content tightly and that in the simple case, the initial display ends up requiring only 50% of the available parent view width. Can I set up the constraints so that the remaining space is divided up according to some user-defined relative weighting mechanism? IE: I want the FirstName and LastName textfields to grow - receiving 20% each of the remaining space with the Birthday button then getting the final extra 10%? Using resistance and hugging properties, I know how to make 1 control receive all the extra space ... but I don't know how to balance free space across several controls. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

So this is where you might use long form. But basic thing is you need to calculate. Then set the metrics. Of course you might need to do some KVO or other means of keeping in sync with resizing. You might also just consider NSStackView designed for this purpose. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Autolayout Freespace
Thanks - and yeah, I'm trying to avoid calculation. And just to clarify, if I need to do some manual calculation, would I be using frames, etc? Frame feels like such a dirty word in autolayout world; is there something else specific to autolayout (like intrinsic size - obviously not in this case) ... Also, if I need to do some manual calculation, would I do that in the view's layoutSubviews - and would I remove and create constraints in that method also - and then tell them to lay themselves out again from that method as well? Back to the original question, do I misunderstand priorities? Can these act as weights at all ... or does the highest priority just win? Thanks.
