正确对齐VStack和HStack

Question

我不知道如何对齐此视图的内容：

我尝试了许多不同的方法：

• 固定大小的vstack
• 设置最大值和最小宽度
• 设置图像的大小等

。

似乎什么事都没有用

import SwiftUI

struct Welcome: View {
    var body: some View {
        VStack {
            Text("Welcome to XXX")
                .font(.title).bold()

            HStack {
                Image(systemName: "magnifyingglass")
                    .foregroundColor(Color(.systemOrange))
                    .imageScale(.large)
                    .padding()
                VStack(alignment: .leading) {
                    Text("Lorem ipsum dolor")
                        .font(.headline)
                    Text("Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore")
                        .font(.subheadline)
                        .foregroundColor(Color(.lightText))
                }
            }.padding()

            HStack {
                Image(systemName: "command")
                    .foregroundColor(Color(.systemOrange))
                    .imageScale(.large)
                    .padding()
                VStack(alignment: .leading) {
                    Text("Lorem ipsum dolor")
                        .font(.headline)
                    Text("Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo.")
                        .font(.subheadline)
                        .foregroundColor(Color(.lightText))
                }
            }.padding()

            HStack {
                Image(systemName: "cube")
                    .foregroundColor(Color(.systemOrange))
                    .imageScale(.large)
                    .padding()
                VStack(alignment: .leading) {
                    Text("At vero eos et accusamus")
                        .font(.headline)
                    Text("At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque ")
                        .font(.subheadline)
                        .foregroundColor(Color(.lightText))
                }
            }.padding()
                Button(action: {
                    print("skip")
                }) {
                    HStack {
                        Spacer()
                        Text("Skip")
                            .font(.subheadline)
                        Spacer()
                    }
                    .foregroundColor(Color(.systemOrange))
                }.padding(.top, 60)

                Button(action: {
                    print("continue")
                }) {
                    HStack {
                        Spacer()
                        Text("Sign In")
                            .font(.subheadline)
                        Spacer()
                    }
                    .padding(12)
                    .foregroundColor(Color(.label))
                    .background(Color(.systemOrange))
                    .cornerRadius(12)
                }.padding()
            }
    }
}

“人机界面指南”建议创建像这样的受欢迎屏幕，这是相当令人讨厌的，而且它们并不提供一个简单的操作。

为了更深入地了解这个问题(请考虑@Mycroft的答案是正确的)：为了在Spacer是必需的问题中显示UI，它不是可选的。我创建了一个最小可行的示例，以准确地显示没有Spacer视图会发生什么：

struct ContentView: View {
    var body: some View {
        VStack {
            HStack {
                Image(systemName: "magnifyingglass")
                    .foregroundColor(Color(.systemOrange))
                VStack(alignment: .leading) {
                    Text("Sed ut perspiciatis unde omnis iste natus")
                }
            }
            HStack {
                Image(systemName: "magnifyingglass")
                    .foregroundColor(Color(.systemOrange))
                VStack(alignment: .leading) {
                    Text("Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo. Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo.")
                }
            }
            HStack {
                Image(systemName: "magnifyingglass")
                    .foregroundColor(Color(.systemOrange))
                VStack(alignment: .leading) {
                    Text("At vero eos ")
                }
            }
        }
    }
}

结果是：

如您所见，结果是完全不对齐的。因此，您必须添加Spacer视图以获得所需的对齐方式。

struct ContentView: View {
    var body: some View {
        VStack {
            HStack {
                Image(systemName: "magnifyingglass")
                    .foregroundColor(Color(.systemOrange))
                VStack(alignment: .leading) {
                    Text("Sed ut perspiciatis unde omnis iste natus")
                }
                Spacer()
            }
            HStack {
                Image(systemName: "magnifyingglass")
                    .foregroundColor(Color(.systemOrange))
                VStack(alignment: .leading) {
                    Text("Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo. Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo.")
                }
                Spacer()
            }
            HStack {
                Image(systemName: "magnifyingglass")
                    .foregroundColor(Color(.systemOrange))
                VStack(alignment: .leading) {
                    Text("At vero eos ")
                }
                Spacer()
            }
        }
    }
}

在上面的布局中，你有“两列”，左边的有图像，右边的有文本。如果您没有指定任何大小，布局系统将定位图像，然后它将给文本剩余的空间。但是，如果需要指定特定大小，还有另一种选择:如果需要左边的图像列是屏幕的一半，则可以使用GeometryReader

struct ContentView: View {
    var body: some View {
        GeometryReader { g in
            VStack {
                HStack {
                    HStack {
                        Spacer()
                        Image(systemName: "magnifyingglass")
                            .foregroundColor(Color(.systemOrange))
                    }
                    .frame(width: g.size.width/2.0)

                    VStack(alignment: .leading) {
                        Text("Sed ut perspiciatis unde omnis iste natus")
                    }
                    Spacer()
                }
                HStack {
                    HStack {
                        Spacer()
                        Image(systemName: "magnifyingglass")
                            .foregroundColor(Color(.systemOrange))
                    }
                    .frame(width: g.size.width/2.0)

                    VStack(alignment: .leading) {
                        Text("Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo. Sed ut ")
                    }
                    Spacer()
                }
                HStack {
                    HStack {
                        Spacer()
                        Image(systemName: "magnifyingglass")
                            .foregroundColor(Color(.systemOrange))
                    }
                    .frame(width: g.size.width/2.0)
                    VStack(alignment: .leading) {
                        Text("At vero eos ")
                    }
                    Spacer()
                }
            }
        }
    }
}

添加一个间隔器似乎可以做到这一点：

            HStack {
                Image(systemName: "cube")
                    .foregroundColor(Color(.systemOrange))
                    .imageScale(.large)
                    .padding()
                VStack(alignment: .leading) {
                    Text("At vero eos et accusamus")
                        .font(.headline)
                    Text("At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque ")
                        .font(.subheadline)
                        .foregroundColor(Color(.lightText))
                }
                Spacer()
            }.padding()
