Yes, SwiftUI provides the ability to restrict the touch region for a drag gesture by using the GestureMask
modifier. This modifier allows you to set the areas of the screen where the gesture will be recognized.
For example, to restrict the drag gesture to only be recognized within a specific view, you can apply the GestureMask
modifier to that view like this:
VStack {
Text("Restricted Drag Gesture")
.padding()
.gesture(
DragGesture()
.onChanged { value in
// handle drag gesture
}
)
}
.gesture(
// Only recognize gesture within the VStack
GestureMask(
gestures: [.drag],
exclusivity: .gesture,
mask: VStack.self
)
)
In this code snippet, the drag gesture will only be recognized when the user is touching within the VStack
. The GestureMask
modifier is applied to the outermost view and specifies that only the drag gesture should be recognized within the VStack
(using the mask
parameter). The exclusivity
parameter indicates that the gesture should not be recognized outside of the VStack
.
