如何在ScrollView中的SwiftUI中创建网格视图？

ScrollView(.vertical){
Spacer(minLength: 10)
Button(action: { }) {
Image("mountain")
//declare your image as resizable, otherwise it will keep its original size
.resizable()
//declare the frame of the image (i.e. the size you want it to resize to)
.frame(width: 160, height: 200)
// place the red rectangle with text in an overlay
// as opposed to HStack where elements are side by side
// here the image will be placed under the rest
.overlay(
//This HStack places the text in the middle with some padding
VStack(spacing: 0) {
Text("Learning to")
.font(Font.custom("Nagietha-Regular", size: 40))
.foregroundColor(.white)
// .padding(.vertical)
Text("Meditate")
.font(.title)
.foregroundColor(.white)
.fontWeight(.heavy)
//.padding(.vertical)
}
//set the background of the text to be semitransparent red
.background(Color.clear.opacity(0.6)),
//this defines the alignment of the overlay
alignment: .center)
//clip everything to get rounded corners
.clipShape(RoundedRectangle(cornerRadius: 10))

有人能给我一些建议吗？没有懒散的网格还有什么办法吗？当然，把
HStackVStack视图。这可能是最简单和最灵活的。我尝试过HStack解决方案，但它会将按钮排成一长列，彼此相邻！这就是为什么a说a对。您可以将带对的HStack
s放入VStack
行中。
