If the distance corresponding开发者_StackOverflow社区 to one degree of longitude is a function of latitude, why do you have to specify longitudeDelta and latitudeDelta when calling MKCoordinateSpanMak
I have a MKCoordinateregion called region. I want to change span of this region without changing it\'s center. I am using following method to change zoom.
I\'m trying to do the union between two MKCoordinateRegion. Does anybody have an idea on how to 开发者_运维技巧do this?There is a MKMapRectUnion function which accepts two MKMapRects so you could firs
enter code hereMKCoordinateRegion viewRegion; viewRegion = M开发者_运维技巧KCoordinateRegionMakeWithDistance(CLLocationCoordinate2DMake(51.4998844,-0.1261814), 10*1000, 10*1000);
How do can I add 2 miles to viewRegion.span.latitudeDelta ? How do can I calculate kTwoMiles? MKCoordinateRegion viewRegio开发者_开发技巧n;
I have an app which is providing a zoomable MKMapView to the user. I want to be able to store the user\'s preferred coordinates and zoom level for when the map view is first displayed.
Could a map开发者_JS百科View.region.span.longitudeDelta or mapView.region.span.latitudeDelta be negative ?The delta cannot be a negative value. Because it is a kind of distance and distance cannot be
Background: I\'m build a series of location-based apps that make heavy use of maps. These maps are annotated with locations fetched from a server, to which I pass regions of the map I need data for (d
Now I have the coordinate of two locations, let say locationA with latitude 40 and longitude -80, locationB with latitude 30 and longitude -70,
Setting the region in MKMapView occasionally results in the span being doubled. This bug seems t开发者_JAVA百科o appear early in the map initialization phase. Although it\'s been reported elsewhere I
