问题描述
下面是我当前视图控制器的屏幕截图.
Below is a screenshot of my current view controller.
我目前试图解决的问题是容器视图文本被固定在 UIView 的顶部.
The problem I'm trying to solve is currently the container view text gets pinned to the top of that UIView.
我以这种方式设置它，以便在较小的设备上它具有滚动视图，这样对我来说最容易可视化和布局元素.
I have it setup this way to on smaller devices it has a scroll view and this way it's easiest for me to visualize and layout the elements.
所以我的目标是在 UIView/容器视图(左侧)上设置最大高度，使其最大高度为 190 像素(因为这是内容的最高高度).
So my goal is to set a max height on that UIView/container view (on the left) to have a max height of 190px (since that is the tallest the content will ever be).
我尝试了上面的解决方案，但它给了我一个错误，说inquality constraint ambiguity.
I tried the above solution but it gives me an error saying inequality constraint ambiguity.
我的目标是最大高度为 190 像素，并在水平和垂直方向上居中查看.
My goal is to just have a max height of 190px and center that view horizontally and vertically.
我怎样才能做到这一点?
How can I achieve this?
编辑
更改底部空间以管理对 = 而不是 >= 的订阅会产生以下结果.
Changing bottom space to manage subscription to = instead of >= produces the following.
推荐答案
您可以通过在高度 = 190 的视图上放置一个低优先级的高度约束来解决这个歧义.
You can fix this ambiguity by placing a low priority height constraint on the View with the height = 190.
这将充当占位符高度约束，可以随时被更高优先级的
This will act as a placeholder height constraint which can be overriden by the higher priority <= 190 constraint anytime.
