如何在 SwiftUI 中将文本与屏幕顶部对齐

Question

我正在尝试将“顶部文本”对齐到屏幕顶部，但找不到方法。 “Top Text”需要对齐iphone屏幕的“notch”附近。

我附上了“顶部文本”当前位置的屏幕截图，需要移到顶部

struct ContentView: View {
    //var newColor : [String: Double] = setColor(red:247, green:186, blue:161)
    var body: some View {
        ZStack {
            VStack(spacing: 0) {
                HStack {
                    Text("Top Text[![enter image description here][1]][1]")
                        .fontWeight(.light)
                        .multilineTextAlignment(.center)
                        .frame(minWidth: 0, maxWidth: .infinity, minHeight: 100)
                        .font(.body)
                        .padding()

                }
                .offset(y: 0)
                .frame(minWidth: 0, maxHeight: 400, alignment: .topLeading)

                VStack {
                    Text("Sign in with Facebook")
                        .fontWeight(.light)
                        .font(.title)
                        .frame(minWidth: 0, maxWidth: .infinity, maxHeight: 50)
                        .padding(EdgeInsets.init(top: 0, leading: 0, bottom: 0, trailing: 0))

                    Text("Sign in with Google")
                        .fontWeight(.light)
                        .font(.title)
                        .padding()
                        .frame(minWidth: 0, maxWidth: .infinity, maxHeight: 50)
                }
            }
            .foregroundColor(Color.black.opacity(0.7))
            .padding()
            .frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity, alignment: .leading)
            .offset(x: 0, y: 0)

        }
        .frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity, alignment: .leading)
        .background(Color.orange.opacity(0.2))
        .edgesIgnoringSafeArea(.all)

    }

}

Answer 1

您可以在HStack 和VStack 之间添加一个Spacer()。不过，这会将其他文本推到底部。您可以在底部的Texts 之后再添加一个Spacer() 以将它们向上推。

这里是基本相同的视图，代码更少：

var body: some View {
    ZStack {
        Color(.orange).opacity(0.2).edgesIgnoringSafeArea(.all)

        VStack(spacing: 10) {
            Text("Top Text[![enter image description here][1]][1]")
                .fontWeight(.light)
                .multilineTextAlignment(.center)
                .font(.body)
                .padding()
            Spacer()
            Text("Sign in with Facebook")
                .fontWeight(.light)
                .font(.title)
            Text("Sign in with Google")
                .fontWeight(.light)
                .font(.title)
            Spacer()
        }
        .foregroundColor(Color.black.opacity(0.7))
        .padding()
    }
}

Answer 2

这是可能的方法

var body: some View {
    ZStack(alignment: .top) { // << made explicit alignment to top
        HStack { // << moved this up to ZStack 
            Text("Top Text")
                .fontWeight(.light)
                .multilineTextAlignment(.center)
                .frame(minWidth: 0, maxWidth: .infinity, minHeight: 100)
                .font(.body)
        }
        .frame(minWidth: 0, maxHeight: 400, alignment: .topLeading)
        VStack(spacing: 0) {

            VStack {
                Text("Sign in with Facebook")
                    .fontWeight(.light)
                    .font(.title)
                    .frame(minWidth: 0, maxWidth: .infinity, maxHeight: 50)
                    .padding(EdgeInsets.init(top: 0, leading: 0, bottom: 0, trailing: 0))

                Text("Sign in with Google")
                    .fontWeight(.light)
                    .font(.title)
                    .padding()
                    .frame(minWidth: 0, maxWidth: .infinity, maxHeight: 50)
            }
        }
        .foregroundColor(Color.black.opacity(0.7))
        .padding()
        .frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity, alignment: .leading)
        .offset(x: 0, y: 0)

    }
    .frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity, alignment: .leading)
    .background(Color.orange.opacity(0.2))
    .edgesIgnoringSafeArea(.all)

}
