我总是想用指尖触摸 x 和 y 坐标。

例如,我还想在使用另一个应用程序时获取坐标。所以我想在后台处理下面的代码。

在后台模式下使用后台处理似乎很好,但我不确定

大家有什么想法吗?非常感谢!

import SwiftUI

struct ContentView: View {
    
    @State private var word: String = ""
    
    @State var xPos: CGFloat = 0
    @State var yPos: CGFloat = 0
    
    var body: some View {
        
        
        ZStack{
            Image(systemName: "")
                .resizable()
                .padding()
                .gesture(DragGesture(minimumDistance: 0, coordinateSpace: .global).onChanged {
                    dragGesture in
                    self.xPos = dragGesture.location.x
                    self.yPos = dragGesture.location.y
                    
                    print(self.xPos,self.yPos)
                    print(dragGesture.translation)
                }
                .onEnded {dragGesture in
                    self.xPos = dragGesture.location.x
                    self.yPos = dragGesture.location.y
                    print("Last",self.xPos,self.xPos)
                    print("Last",dragGesture.translation)
                })
            
            VStack{
                HStack{
                    Text("\(xPos)")
                    Text("\(yPos)")
                }
                VStack {
                    TextField("please write", text: $word)
                        .textFieldStyle(RoundedBorderTextFieldStyle())  
                        .padding()  
                    
                    Text("\(word)")
                    
                }
            }
        }
        
    }
    
}






struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
