以编程方式禁用UIView的安全区域布局指南 [英] Disable Safe Area Layout Guides For UIView Programmatically

问题描述

安全区域布局指南.该如何用代码完成?

Safe area layout guides can be disabled in Interface Builder by unchecking the Use Safe Area Layout Guides. How can this be done in code?

我没有注意到与复选框直接对应的iOS11可用布尔值.

I didn't notice an iOS11-available boolean that directly corresponds with the checkbox.

推荐答案

我认为以编程方式完成此操作的唯一方法是覆盖safeAreaLayoutGuide属性.

I think the only way to accomplish this programmatically is to override the safeAreaLayoutGuide property.

override var safeAreaLayoutGuide: UILayoutGuide {
    return UILayoutGuide()
}

当通过IB禁用它时，它仍然返回一个UILayoutGuide，但是layoutFrame为零，通过返回UILayoutGuide的一个实例，您基本上是在做同样的事情.

When you disable it through IB it still returns a UILayoutGuide but with zero layoutFrame, by returning an instance of UILayoutGuide, you are basically doing the same.
