问题描述
我想在为 iOS 和 iPadOS 构建时显示不同的视图.目前,我知道我可以做到
I'd like to display different views when building for iOS and iPadOS. Currently, I know I can do
import SwiftUI
struct ContentView: View {
#if targetEnvironment(macCatalyst)
var body: some View {
Text("Hello")
}
#else
var body: some View {
Text("Hello")
}
#endif
}
在 macOS 和 iPadOS/iOS 之间显示不同的视图(在 Swift 4/5 中引入).但我如何区分后者?我似乎无法使用 targetEnvironment ...
to display different views between macOS and iPadOS/iOS (introduced in Swift 4/5). But how do I differentiate between the latter? I can't seem to use targetEnvironment...
推荐答案
我在我的代码中使用了这个:
I use this in my code:
private var idiom : UIUserInterfaceIdiom { UIDevice.current.userInterfaceIdiom }
private var isPortrait : Bool { UIDevice.current.orientation.isPortrait }
然后你可以这样做:
var body: some View {
NavigationView {
masterView()
if isPortrait {
portraitDetailView()
} else {
landscapeDetailView()
}
}
}
private func portraitDetailView() -> some View {
if idiom == .pad {
return Text("iPadOS")
} else {
return Text("iOS")
}
}
