如何设置动态宽度&iOS自动布局中视图的高度? [英] How to set dynamic width & height of a view in autolayout in iOS?

问题描述

我的超级视图中有一个 UIView.我已经设置了一些约束.现在我希望不同设备上的视图大小应该不同.如果我设置了固定宽度 &高度然后我得到错误的结果.我尝试使用用户纵横比，但这会使多个设备上的视图太大或太小.

I have a UIView in my super view.I have set it some constraints.Now I want the size of view should be different on different devices.If I set the fix width & height then I get the wrong result.I have tried to user aspect ratio but that make a view too big or too small on multiple devices.

我想要身高&宽度应该以相同的比例增加，它必须在所有设备上看起来都一样.我想要灵活的视图高度和宽度.请告诉如何做到这一点?

I want the height & width should increase in equal proportion that it must look same all devices.I want to have flexible height and width of the view.Please tell how to do this?
