Show status bar with animation causes view to move up 20px so its under the status bar

Question

I have a UIViewController that shows and hides the status bar. Hiding the status bar works no problem, however when I show the status bar using:

 [[UIApplication sharedApplication] setStatusBarHidden:NO                                         withAnimation:UIStatusBarAnimationSlide];

Causes the contents of the View to move up 20px so it ends up under the status bar. I dont know what else I can provide but this description, all that happens is when I hide the status bar, there is 20px of white space at the top where the status bar would be (this is what I want) but when I show the status bar the view moves up under the status bar (this is not what I want). The desire is to show and hide the status bar without effecting the UIViewController and its contents.

Answer 1

我有同样的问题。我设法在故事板中修复它。

正在向上移动的视图的顶部约束设置为顶部布局指南。我将其更改为指向 Superview.Top ，视图停止移动。

要在顶部布局指南中明确使用Superview，您需要使用Pin（故事板左下角的按钮）并在设置约束之前取消选中＆＃34; Constrain to margin＆＃34;

Answer 2

我通过删除此ViewController上的自动布局并在以下位置手动设置视图布局来解决此问题：

-(void)viewDidLayoutSubviews

似乎解决了这个问题。为@ThatGuy欢呼，让我朝着正确的方向前进。
