Xcode AutoLayout, Make Margin proportional with height

Question

I am having a big time figuring out how to make the margin of two objects proportional. If i choose aspect ratio on Xcode it gives me the option for adjust the height of my object proportional screen height. and thats not my case. I want the margin between a button and screen bottom to be proportional to screen height. And i want it to be done using Xcode "No Code".

Your support is highly appreciated.

Thank you

Answer 1

Use the multiplier property of NSLayoutConstraint !

First, set the equal height constraint from your view to its superview with the multiplier you wish. You can use Ctrl + drag from your view to the superview.

Then set another constraint at 0 from the top of your view to the superview and a equal width constrain with a multiplier to 1 from your view to the superview.

Done !

Answer 2

Add transparent view and make it proportional to height. Bind you Done button with this transparent view. There you can find how to make it.
