在SwiftUI中,布局约束和自动调整是通过使用不同的属性和方法来实现的
struct ContentView: View {
var body: some View {
GeometryReader { geometry in
VStack {
Text("Hello, SwiftUI!")
.background(Color.red)
.onAppear {
print("Geometry: \(geometry.size)")
}
}
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(Color.blue)
}
}
}
struct ContentView: View {
var body: some View {
HStack {
Text("Left")
.alignment(.leading)
Text("Center")
.alignment(.center)
Text("Right")
.alignment(.trailing)
}
.padding()
}
}
struct ContentView: View {
var body: some View {
HStack {
Text("Left")
Spacer()
Text("Right")
}
}
}
struct ContentView: View {
var body: some View {
Row {
Text("Left")
Text("Center")
Text("Right")
}
.axis(horizontal)
}
}
struct ContentView: View {
var body: some View {
HStack {
Text("Left")
.priority(.high)
Text("Center")
Text("Right")
.priority(.low)
}
}
}
通过使用这些属性和方法,你可以轻松地实现布局约束和自动调整功能。
