模态选择器没有向右滚动 SwiftUI [英] Modal picker not scrolling right SwiftUI

问题描述

我创建了一个模态，但它似乎在选择上有一个错误.向左滚动时，它向右滚动，我必须到左边的边缘才能滚动，这是它的外观:

I created a modal but it seems to have a bug on the selection. When scrolling the left, it scrolls the right, I have to go to the very edge of the left to be able to scroll, this is how it looks:

import SwiftUI

struct ContentView: View {

@State var showingModal = false
@State var hours: Int = 0
@State var minutes: Int = 0

var body: some View {

    ZStack {
        VStack {
            Button("Show me"){
                self.showingModal = true
            }

            if $showingModal.wrappedValue {
                VStack(alignment: .center) {
                    ZStack{
                        Color.black.opacity(0.4)
                            .edgesIgnoringSafeArea(.vertical)
                        // this one is it
                        VStack(spacing: 20) {
                            Text("Time between meals")
                                .bold().padding()
                                .frame(maxWidth: .infinity)
                                .background(Color.yellow)
                                .foregroundColor(Color.white)

                            HStack {
                                Spacer()
                                VStack {
                                    Picker("", selection: $hours){
                                        ForEach(0..<4, id: \.self) { i in
                                            Text("\(i) hours").tag(i)
                                        }
                                    }
                                    .frame(width: 150, height: 120)
                                    .clipped()
                                }

                                VStack {
                                    Picker("", selection: $minutes){
                                        ForEach(0..<60, id: \.self) { i in
                                            Text("\(i) min").tag(i)
                                        }
                                    }
                                    .frame(width: 150, height: 120)
                                    .clipped()
                                }
                            }

                            Spacer()

                            Button(action: {
                                self.showingModal = false
                            }){
                                Text("Close")
                            } .padding()
                        }
                        .frame(width:300, height: 300)
                        .background(Color.white)
                        .cornerRadius(20).shadow(radius: 20)
                    }   
                }
            }
        }
    }
}
}

我该如何修复那个小错误?我尝试使用布局但没有用...任何帮助将不胜感激

How can I fix that little bug? I tried playing around with the layout but no use... any help would be appreciated

推荐答案

如果我告诉你你的 Picker 不工作的原因是这条线怎么办?

What if I told you the reason your Picker not working was this line?

.cornerRadius(20).shadow(radius: 20)

不幸的是，SwiftUI 仍然有很多问题，有时它没有做它应该做的事情，尤其是 Pickers 不是那么可靠.我想我们需要等待 SwiftUI 的下一次迭代，但现在您可以用下面的代码替换该行:

Unfortunately, SwiftUI is still quite buggy and sometimes it doesn't do what it is supposed to do and especially Pickers are not that reliable. I guess we'll need to wait and see the next iteration of SwiftUI, but for now you can replace that line with the code below:

.mask(RoundedRectangle(cornerRadius: 20))
.shadow(radius: 20)
