SwiftUI:iPad上不必要的拆分视图 [英] SwiftUI: unwanted split view on iPad

问题描述

问题:Pad上的视图显示为 不需要 的拆分视图.

Problem: a view on Pad shows up with unwanted split view.

我当前的设置是: Catalina OSX Beta 5 + Xcode 11 Beta 5

My current setup is: Catalina OSX beta 5 + Xcode 11 Beta 5

这是我使用的代码，以及一个导航视图和一个导航标题:

Here is the code I used, with a Navigation View and a Navigation Title:

import SwiftUI

struct SwiftUIView: View {
    var body: some View {
        NavigationView {
            Text("Search")
                .navigationBarTitle(Text("Search"))
        }
    }
}

#if DEBUG
struct SwiftUIView_Previews: PreviewProvider {
    static var previews: some View {
        SwiftUIView()
    }
}
#endif

在iPad(物理设备和预览版)上模拟而不是全屏显示时，我得到了以下分屏显示:

When simulated on iPad (both physical device and preview) instead of a full screen view, I get this split screen view:

如果我只有一个视图而没有NavigationView，那么我会得到全屏视图:

If I have just a view, with no NavigationView, I get a full screen view:

import SwiftUI

struct SwiftUIView: View {
    var body: some View {
        Text("Hello World!")
    }
}

#if DEBUG
struct SwiftUIView_Previews: PreviewProvider {
    static var previews: some View {
        SwiftUIView()
    }
}
#endif

如何在iPad上将NavigationView全屏显示(而不是分屏显示)?

How can I make a NavigationView full screen (not split screen) on iPad?

推荐答案

您可以将.navigationViewStyle(StackNavigationViewStyle())修改器应用于NavigationView！

You can apply the .navigationViewStyle(StackNavigationViewStyle()) modifier to the NavigationView!

... 
    NavigationView {
        Text("Hello world!")
    }
    .navigationViewStyle(StackNavigationViewStyle())
...

下面，我从他的评论中回答亚历山大的问题:

Below, I am answering Alexandre's questions from his comment:

• 为什么全屏不是iPad的默认视图?这只是Apple做出的选择...

• Why full view is not the default for iPad? That's just a choice made by Apple...

为什么此修饰符位于NavigationView闭包之外，而导航标题位于内部... 也许可以这样澄清:https://stackoverflow.com/a/57400873/11432719

Why this modifier goes outside of NavigationView closure, while the Navigation Title goes inside... Maybe this gives clarification: https://stackoverflow.com/a/57400873/11432719
