iPad上的ActionSheet未正确显示SwiftUI
iPad上的ActionSheet未正确显示SwiftUI
提问于 2020-12-16 21:29:35
我正在尝试让我的用户在ActionSheet中选择拍照或从库中挑选
它在Iphone上运行良好，但在Ipad上效果不佳
在Ipad上: ActionSheet在屏幕顶部，不可读...
我在StackOverflow上读到的关于这个问题的所有问题都是关于crash的(这不是我的情况)，或者比SwiftUI更老
我的代码：
struct AjoutView: View {
@State private var image : Image?
@State private var shouldPresentImagePicker = false
@State private var shouldPresentActionScheet = false
@State private var shouldPresentCamera = false
var body: some View {
VStack{
...
}
.sheet(isPresented: $shouldPresentImagePicker, onDismiss: loadImage) {
SUImagePickerView(sourceType: self.shouldPresentCamera ? .camera : .photoLibrary, image: self.$image, isPresented: self.$shouldPresentImagePicker, dispId: disp.id)
}
.actionSheet(isPresented: $shouldPresentActionScheet) { () -> ActionSheet in
ActionSheet(title: Text("Ajouter une photo"), buttons: [ActionSheet.Button.default(Text("Prendre une photo"), action: {
self.shouldPresentImagePicker = true
self.shouldPresentCamera = true
}), ActionSheet.Button.default(Text("Importer depuis mes photos"), action: {
self.shouldPresentImagePicker = true
self.shouldPresentCamera = false
}), ActionSheet.Button.cancel()])
}
}
}我的代码中缺少什么？

将它附加到View中的某个东西上，比如让它显示出来的Button。
struct ASSample: View {
@State var shouldPresentActionScheet1: Bool = false
@State var shouldPresentActionScheet2: Bool = false
var body: some View {
VStack{
Button("show-sheet1", action: {
self.shouldPresentActionScheet1.toggle()
})
.actionSheet(isPresented: $shouldPresentActionScheet1) { () -> ActionSheet in
ActionSheet(title: Text("Ajouter une photo"), buttons: [ActionSheet.Button.default(Text("Prendre une photo"), action: {
//self.shouldPresentImagePicker = true
//self.shouldPresentCamera = true
}), ActionSheet.Button.default(Text("Importer depuis mes photos"), action: {
//self.shouldPresentImagePicker = true
//self.shouldPresentCamera = false
}), ActionSheet.Button.cancel()])
}
Spacer()
Button("show-sheet2", action: {
self.shouldPresentActionScheet2.toggle()
})
.actionSheet(isPresented: $shouldPresentActionScheet2) { () -> ActionSheet in
ActionSheet(title: Text("Ajouter une photo"), buttons: [ActionSheet.Button.default(Text("Prendre une photo"), action: {
//self.shouldPresentImagePicker = true
//self.shouldPresentCamera = true
}), ActionSheet.Button.default(Text("Importer depuis mes photos"), action: {
//self.shouldPresentImagePicker = true
//self.shouldPresentCamera = false
}), ActionSheet.Button.cancel()])
}
}
}
}
struct ASSample_Previews: PreviewProvider {
static var previews: some View {
ASSample()
}
