问题 I have a coordinate region that I have determined contains the limits of what I want to show for my app. I have set this up as an MKCoordinateRegion with center point lat, longitude and a span. How do I determine if the current userLocation is inside of my coordinate region? 回答1: Use map rects. Here's an example using the map's current visible rect. With regards to your question, you could use convertRegion:toRectToView: to first convert your region to a MKMapRect beforehand. MKMapPoint

I made this method to check if an user location is inside a polygon on a map view (mapkit). I pass to the method the current user location (CLLocationCoordinate2D) and return a boolean just to know if the user is in a polygon or not. func userInsidePolygon(userlocation: CLLocationCoordinate2D ) -> Bool{ // get every overlay on the map let o = self.mapView.overlays // loop every overlay on map for overlay in o { // handle only polygon if overlay is MKPolygon{ let polygon:MKPolygon = overlay as! MKPolygon let polygonPath:CGMutablePathRef = CGPathCreateMutable() // get points of polygon let

How to Increase the Radius of userLocation Annotation in Mapkit

由 拟墨画扇 提交于 2019-12-01 10:26:16
问题 My app takes user permission and move the map to the location. And at that position by default MapKit add a blue icon which is generating some pulse. I've searched around but I found how to add a 1000m circle around userLocation . I don't want that. You can say I'm looking to customize the userLocation default annotation . The blue pulse it generates I want to increase that radius . And when this blue pulse hits a custom annotation there should be a method triggered. So how to achieve that?
