[英]Center multiple views with varying height using autolayout
问题描述
This answer: https://stackoverflow.com/a/25898949/1364053 is suitable for my problem to some extent. 
这个答案： https : //stackoverflow.com/a/25898949/1364053在某种程度上适合我的问题。 What I need is there are three views in my container view. 我需要的是容器视图中的三个视图。
The middle one is a scroll view. 中间一个是滚动视图。 If I pin height and width of all three views and use the ratio method as described in the above link, all works fine. 如果我固定了所有三个视图的高度和宽度，并使用上述链接中所述的比率方法，则一切正常。
But I need the middle scrollview to grow to some extent, let's say the current height of the scroll view is 30, If the device height is increased it should grow to a max of 40 but not more than that (<= constraint). 但是我需要中间的滚动视图在某种程度上增长，比方说当前滚动视图的高度是30。如果设备的高度增加，它应该增长到最大40，但不能超过这个最大值（<=约束）。
Ok..So I tried giving two constraints to the middle view. 好的，所以我尝试给中间视图施加两个约束。 The <= constraint has higher priorty (750) than the = constraint (250).. but when the screen size is increased.. the height stays the same. <=约束具有比=约束（250）高的优先级（750）。但是，当屏幕尺寸增加时，高度保持不变。
