[英]Storyboard: align button in custom UIView to another button in parent UIView using auto-layout constraints?
Assume a custom UIView, CustomView, that is designed with a Xib file. 假定使用Xib文件设计的自定义UIView,CustomView。 Inside CustomView is a UIButton, CustomButton.
在CustomView内部是一个UIButton,CustomButton。
ParentView is a UIView that contains CustomView. ParentView是一个包含CustomView的UIView。
With Storyboard, is it possible to create an auto-layout constraint that center aligns CustomButton with another button in ParentView? 使用情节提要,是否可以创建一个自动布局约束,以使CustomButton与ParentView中的另一个按钮居中对齐?
No it is not possible to do what you are trying to do in storyboard. 不,您不可能在情节提要中做您想做的事情。 You would have to do it programatically.
您将必须以编程方式进行操作。
