有什么办法暗示自动延迟以在尊重约束时尽可能小的视图？
因此，我有一个视图，v，我想以下面的方式约束：
v的大小最小：mv v v应水平扩展以适合内部包含的文本视图，tv应集中在Supperiew中，sv v vv。 应尽可能小。
因此，我试图通过以下约束来实现这一目标：
v.width >= m
v.width >= t.width
v.centerX == s.centerX
借助这些约束，问题在于，视图增长以填补整个监督。
如果我删除约束v.width＆gt; = m，则视图缩放到包裹t与可能性一样紧密。
无论如何，是否有暗示自动布局，它应该尝试使v尽可能小时，而不会破坏约束？
So I have a view, v, which I want to constrain in the following way:
vhas a minimum size:mvshould scale horizontally to fit the text view contained inside,tvshould be centered inside the superview,svshould be as small as possible.
So I have tried to achieve this with the following constraints:
v.width >= m
v.width >= t.width
v.centerX == s.centerX
With these constraints, the problem is that the view grows to fill the entirety of the superview.
If I remove the constraint v.width >= m then the view scales to wrap t as closely as possilble.
Is there anyway to hint to auto layout that it should try to make v as small as possible without breaking the constraints?

当指定不等式的宽度/高度时，
如果T.Width是＆gt; gt; M，然后有一个答案，可以满足两个方程式的满足。
但是T.Width可能是Lt; M，所以您需要不同的优先级：
If you have two >= priorities then there's ambiguity about how much greater the value should be to satisfy all the equations
Now if t.width is < m然后它将忽略默认的低优先级，而v.width将为m
When specifying width/height with inequalities you generally need to have opposite >= and <=
This way if t.width is > m, then there's an answer for how wide satisfies both equations.
But t.width could be < m, so you need different priorities:
If you have two >= priorities then there's ambiguity about how much greater the value should be to satisfy all the equations
Now if t.width is < m then it will just ignore the default low priority and v.width will be m
