[英]Tabbar iPad App to Sidebar macOS Catalyst app
I am struggling to figure out how to turn my tabbar
based iPad app into a sidebar navigation based Catalyst
app.我正在努力弄清楚如何将基于标签栏的tabbar
应用程序转变为基于侧边栏导航的Catalyst
应用程序。 Similar to the screenshot that Apple shows:类似于 Apple 显示的屏幕截图:
You can see in the screenshot above the iPad app uses a tabbar
layout but the macOS
Catalyst app used a left sidebar navigation.您可以在上面的屏幕截图中看到tabbar
应用程序使用标签栏布局,但macOS
Catalyst 应用程序使用左侧边栏导航。
How can I do this and convert my iPad app to use a sidebar in macOS
?如何执行此操作并将我的 iPad 应用程序转换为在macOS
中使用侧边栏?
You can do something like this你可以做这样的事情
#if targetEnvironment(macCatalyst)
// here use the NavigationView + NavigationLinks to make the sidebar on macOS
#else
// here use the Tab Bar view.
#endif
You can use this to create entire alternate views if you need.如果需要,您可以使用它来创建整个备用视图。
For example:例如:
#if targetEnvironment(macCatalyst)
struct MyView: View {
var body: some View {
Text("Im in macOS")
}
}
#else
struct MyView: View {
var body: some View {
Text("Im in iOS")
}
}
#endif
