Hi,
I want Map() zoom level adjusted according to speed of the user.
I'm currently using the following to initialize Map position:
@State private var position: MapCameraPosition = .userLocation(followsHeading: true, fallback: .automatic)
var body: some View {
Map(position: $position) {...}
}
I get speed from CoreLocationl. How can I adjust zoom level, or camera position, to accomplish this?
Thanks!
I've found that using MapCameraBounds adjusts zoom level
mapCameraBounds = MapCameraBounds(minimumDistance: minimumDistance, maximumDistance: maximumDistance)
I now want to make the changes smooth and have thought of using .onChange(of:) and withAnimation, as follows:
.onChange(of: locationManager.currentLocation?.speed) { oldValue, newValue in
withAnimation(.spring(duration: 1.0)) {
let speed = newValue ?? 0.0
if speed > 20 {
minimumDistance = 5000.0
maximumDistance = 10000.0
} else {
minimumDistance = 1000.0
maximumDistance = 2000.0
}
mapCameraBounds = MapCameraBounds(minimumDistance: newValue, maximumDistance: maximumDistance)
}
}
Map(position: $position, bounds: mapCameraBounds)
But that doesn't work, zoom changes are not animated. Is there a proper way of doing this?
My previous attempt with MapCameraBounds() was not the correct one.
There are at least two conflicting ways to set camera position.
The first one gives me user location and heading, the second one lets me specify region and zoom in/out (with animation).
I've added MapUserLocationButton() to show user location/heading but its turned off as soon as MKCoordinateRegion updates.
How do I combine these to get both effects?
Thanks
I'm still looking for the experts out there to help me with this problem. It does not appear that there is a way to arbitrarily zoom the map to the desired level, while displaying annotations using Annotation() and tracking user location using .userLocation(followsHeading:). I must be missing something but looked through the documentation and am not seeing a way to do this. Thanks!
currently having exact same problem. When I dragged map region, I lost the user location blue dot and need to tap on MapUserLocationButton() show again.
