如何从视图控制器中删除边距?

问题描述

我使用情节提要创建了一个新项目.现在，我想在默认的 ViewController 中添加一个 UIView.当我尝试使用 AutoLayout 将约束添加到带有父 ViewController 的 UIView 时，它在前导和尾随空格处显示 -16 而不是 0.这使得 UIView 小于默认的 UIViewController 宽度.我怎么能删除这个?请帮忙.

I have created a new project using storyboard. Now, I want to add a UIView into the default ViewController. When I tried to add constraint using AutoLayout to the UIView with it's parent ViewController, it is showing -16 instead of 0 at both leading and trailing space. Which make the UIView smaller than the default UIViewController width. How could I remove this? Please help.
