SwiftUI Gestures - 이미지 드래그
이미지를 드래그하고 화면의 특정지역으로 드래그 했을때 경고표시 나게 하는 방법
import SwiftUI
struct ContentView: View {
@State private var position = CGPoint(x: 100, y:100)
let bounds = UIScreen.main.bounds
@State private var danger : Bool = false
var body: some View {
VStack{
Image("Image")
.resizable()
.frame(maxWidth: 100, maxHeight: 100)
.zIndex(1.0)
.position(position)
.gesture(DragGesture()
.onChanged({(value) in
position = value.location
if position.y > bounds.height/2 {
danger = true
} else {
danger = false
}
})
.onEnded({(value) in
})
)
HStack{
Text("Danger")
}.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(danger ? Color.red: Color.blue)
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
