SwiftUI - 底部工作表有一个区域可以更改与内容接触的背景
[英]SwiftUI - the bottom sheet has an area which changes the background on contact with content
问题描述
There is a bottom sheet in the settings default app, in this bottom sheet there is a certain area with a button that changes the background when it comes into contact with content such as a NavigationBar or a TabView .
设置默认应用程序中有一个底部工作表，在这个底部工作表中有一个带有按钮的特定区域，当它接触到NavigationBar或TabView等content时，该按钮会更改background 。 How can this be implemented?如何实施？
I tried putting a button in toolbar on the bottom bar, it worked fine and close to what I wanted, but the area is too small.我尝试在底部栏的工具栏中放置一个按钮，它工作正常并且接近我想要的，但是面积太小了。 I also tried .safeAreaInset with .bottomBar placement, but how to make the background change from what is above the content and disappear when there is no content below it like in video.我还尝试了.safeAreaInset和.bottomBar放置，但是如何使background从content content消失。
