为什么 SwiftUI 中的 VStack 之间存在间隙?
Why is there a Gap between VStacks in SwiftUI?
在用红线绘制的区域中可以看到白色。如果我改变最具包容性的 Vstack 的背景颜色,那个白色区域就会改变。
删除 spacer() 行无效。
为什么中间没有space却有空隙?
struct TabbarView: View {
var body: some View {
VStack{
Spacer()
ZStack{
Color.orange.opacity(0.5)
VStack(spacing: 0){
Text("Home")
.padding()
}
}
Spacer()
HStack{
VStack{
Image(systemName: "homekit")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: UIScreen.main.bounds.size.width / 15, height: UIScreen.main.bounds.size.height / 25)
}
}
.frame(width: UIScreen.main.bounds.size.width, height: UIScreen.main.bounds.size.height / 13)
.background(Color.purple)
}
.ignoresSafeArea()
// .background(Color.purple.shadow(radius: 2))
}
}

您可以为 VStack 添加:
VStack {}
.frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity, alignment: .center)
更新:
struct ContentView: View {
var body: some View {
ZStack {
Color.orange.opacity(0.5)
VStack {
Spacer()
VStack(spacing: 0){
Text("Home")
.padding()
}
Spacer()
HStack {
VStack {
Image(systemName: "homekit")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 25, height: 25, alignment: .center)
.frame(width: UIScreen.main.bounds.size.width / 15, height: UIScreen.main.bounds.size.height / 25)
}
}
.frame(width: UIScreen.main.bounds.size.width, height: UIScreen.main.bounds.size.height / 13)
.background(Color.purple)
}
}
.ignoresSafeArea()
.frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity)
}
}
你错误地使用了嵌套,标签有一个原生的 TabView
结果:
