是否可以将UIView的顶部固定在导航栏的底部? [英] Is it possible to pin a UIView's top to the bottom of the navigation bar?

问题描述

我试图将我的UIView定位在导航栏下为20pt，但是当我将其相对于视图控制器上的视图设置时，它仍位于导航栏下为20pt，并且我不想对其进行硬编码

I'm trying to position my UIView to be 20pt under the navigation bar, but when I set it relative to the view on the view controller it's still under the navigation bar at 20pt, and I don't want to hardcode it.

是否可以将其放置在导航栏之外?

Is it possible to position it away from the navigation bar?

推荐答案

尝试使用TopLayoutGuide添加约束，

Try adding contraint with TopLayoutGuide,

TopLayoutGuide与self.view之间的主要区别在于，顶部布局指南以bottom of status bar + bottom of navigation bar(if exist)开头，但self.view始终从iOS 7中的半透明导航栏的(0,0)坐标开始.

The main difference between TopLayoutGuide and self.view is, top layout guide starts with bottom of status bar + bottom of navigation bar(if exist), but self.view always start from (0,0) coordinate in iOS 7 for translucent navigation bar.

因此，在您的情况下，您应该尝试从顶部布局指南中进行固定.

So in your case you should try pinning from top layout guide.
