混合方法以编程方式创建自动布局约束

Question

I am trying to create Autolayouts programmatically so I referred the [Autolayout Guide][1]. In which I found three techniques to programmatically create Autolayouts

1. Layout Anchors
2. NSLayoutConstraint Class
3. Visual Format Language

Regarding Visual Format Language Autolayout Guide Says:

The notation emphasizes good visualization over completeness. Therefore some constraints (for example, aspect ratios) cannot be created using the visual format language.

Can I mix Visual Format Language with Layout Anchors to create other constraints with Visual Format Language and Aspect ratio constraints with Layout Anchors .

Answer 1

当然-一旦创建了布局约束（通过任何方式），它就是正常的布局约束。
