blocks|key|1657635|text|实际上，我相信答案是:要实现全屏，我们不应该使用安全区域支持。在未检查Interface大小检查器视图上的安全区域相对边距和安全区布局指南之后，我得到了预期的结果：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1657636|​|1657637|📷|atomic|offset|length|1657638|1657639|事实上，我要说的是，安全区的概念是一个肯定不会被任何系统图标或圆形边框重叠的区域，全屏正好相反。|1657640|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://developer.qcloudimg.com/http-save/yehe-900000/367e9c476d472155c1765681a46317a2.png|imageAlt^0|0|0|0|1|0|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|V|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|W|8|@]|9|@$G|X|H|Y|1|Z]]|A|$]]|$1|I|3|C|5|6|7|10|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|11|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|M|$N|$5|O|P|Q|A|$R|S|T|-4]]]]

Actually I believe the answer is this: to accomplish full screen we should NOT use safe area support. After I unchecked Safe Area Relative Margins and Safe Area Layout Guide on the view in Interface Builder Size Inspector I got the expected result:

<a href="https://i.stack.imgur.com/Huxy1.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Huxy1.png" alt="enter image description here"></a>

In fact I would say that the idea of Safe Area is that of an area which will for sure not be overlapped by any of the system icons, or rounded borders, full screen is the opposite of it.

This answer is simple and worked for me .. follow these sequences:
1- select the background image and open constraints window
2- uncheck constrain to margins
3- as in picture : select (View) not (safe area) from the small arrow in the corner of edit value rectangle .. apply this for all 4 values
4 - enter value 0 for all 4 values and hit Enter
and Done

blocks|key|21873|text|我通过这样的上下设置解决了问题。xcode版本为11.6|type|unstyled|depth|inlineStyleRanges|entityRanges|data|21874|📷|atomic|offset|length|21875|​|21876|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://developer.qcloudimg.com/http-save/yehe-900000/3ee4340ae5d7bd497e00c0ac4f025881.png|imageAlt^0|0|0|1|0|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|S|8|@]|9|@$E|T|F|U|1|V]]|A|$]]|$1|G|3|H|5|6|7|W|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|X|8|@]|9|@]|A|$]]]|J|$K|$5|L|M|N|A|$O|P|Q|-4]]]]

I solved problem by setting top and bottom like this. xcode version is 11.6<a href="https://i.stack.imgur.com/ZJBsR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZJBsR.png" alt="enter image description here" /></a>

The new HIG for iPhone X available <a href="https://developer.apple.com/ios/human-interface-guidelines/overview/iphone-x/" rel="noreferrer">here</a>, specify:
"Provide a full-screen experience. Make sure backgrounds extend to the edges of the display, and that vertically scrollable layouts, like tables and collections, continue all the way to the bottom."

Now I'd like to understand how to accomplish that with Xcode 9 GM, since it seems to me that the only view allowed to extend to the whole screen is the UIViewController root view, and that whenever I try to drag constraints for a view above that, i.e. WKWebView to the root view, the constraints get actually connected to the safe area, leaving both the top and bottom areas empty as displayed in the storyboard here:

<a href="https://i.stack.imgur.com/SFcIu.png" rel="noreferrer"><img src="https://i.stack.imgur.com/SFcIu.png" alt="enter image description here"></a>

Please note the answer <a href="https://stackoverflow.com/questions/46190975/iphone-x-full-screen-issue">here</a> specifies to use the safe area, but that doesn't work because using it results in the following simulator result where WKWebView is NOT extending to the edges of the screen:

新的iPhone X可用指定：“提供全屏体验。确保背景延伸到显示的边缘，垂直滚动布局，如表和集合，一直持续到底部。”现在，我想了解如何使用Xcode 9 GM实现这一点，因为在我看来，唯一允许扩展到整个屏幕的视图是UIViewController根视图，而且每当我试图将约束拖到上面的视图(即WKWebView到根视图)时，约束实际上会连接到安全区域，而在故事板中显示的顶部和底部区域都是空的：​​请
