X $ C $Ç自动版式，使保证金比例随高度 [英] Xcode AutoLayout, Make Margin proportional with height

问题描述

我有一个大的时间搞清楚如何让两个物体的保证金比例。如果我选择在X $ C $纵横比C它给我调整我的目标比例屏幕高度的高度的选项。并且那不是我的情况。我希望有一个按钮与屏幕底部之间的差额正比于屏幕的高度。我想它利用X code没有code来完成。

使用NSLayoutConstraint的乘数财产！

Use the multiplier property of NSLayoutConstraint !

首先，从你的观点的平等高度约束设置为与您希望乘数上海华。您可以使用Ctrl +拖动从您欣赏到上海华。

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.

然后从视图顶部到上海华设置其他限制在0和平等的宽度从您欣赏到上海华乘数为1约束。

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.

完成！
