I'm trying to fail LongPressGesture with maximumDistance when I move my finger away from the Image but that doesn't work, it keeps printing the message "Pressed"
struct ContentView: View {
@GestureState private var isDetectingPress = false
var body: some View {
Image(systemName: "trash")
.resizable().aspectRatio(contentMode: .fit)
.frame(width: 100, height: 100)
.scaleEffect(isDetectingPress ? 0.5 : 1)
.animation(.easeInOut(duration: 0.2))
.gesture(LongPressGesture(minimumDuration: 0.01, maximumDistance: 10).sequenced(before:DragGesture(minimumDistance: 0).onEnded {_ in
print("Pressed")
})
.updating($isDetectingPress) { value, state, _ in
switch value {
case .second(true, nil):
state = true
default:
break
}
})
}
}
Change your updating
modifier to detect if there is a drag amount:
.updating($isDetectingPress) { value, state, _ in
switch value {
case .second(true, nil):
state = true
case .second(true, _): // add this case to handle `non-nil` drag amount
state = false
default:
break
}
And set a minimum distance (eg. 100) for DragGesture
in DragGesture
itself:
DragGesture(minimumDistance: 100)
and not in LongPressGesture
:
//LongPressGesture(minimumDuration: 0.01, maximumDistance: 100) // remove `maximumDistance`
LongPressGesture(minimumDuration: 0.01)
