Getting "region" in MKMapView
I am adding a set of anotations that I getting from Open Street Maps (OSM) and that requires that I first limit to a geographical range.
In order to do that, I need to know that lat/long range of the display.
'get_center_coordinate()' works great for "where" I am but to get limit the range I need to know the "span" of the mapview.
I thought that it would be easy to just copy the code from get_center_coordinate() to create get_region() (see below) but my code causes an error; "No method found for region"
The Apple documentation MKMapView shows that 'centerCoordinate' only differs from 'region' in the return type ('CLLocationCoordinate2D' vs 'MKCoordinateRegion'
My understanding of objective C is poor at best and so is nderstanding of the objc_util module.
Any help I can get whether it be a hint or actual working code would be appreciated.
*This method works great
def get_center_coordinate(self): """Return the current center coordinate as a (latitude, longitude) tuple""" coordinate = self.mk_map_view.centerCoordinate(restype=CLLocationCoordinate2D, argtypes=) return coordinate.latitude, coordinate.longitude
This method errors: "No method found for region"
@on_main_thread def get_region(self): """Return latitude /longitude of the view's center and the zoom level (specified implicitly as a latitude/longitude delta)""" region = self.mk_map_view.region(restyle=MKCoordinateRegion,argtypes=) return region.center.latitude, region.center.longitude, region.span.d_lat, region.span.d_lon
@becktrex, it’s probably just the typo, ”restyle”.
Yep, that was it restyle s/b restype
The problem with “cut and paste” programming is that I don’t know enough about what I’m seeing to see the obvious. In this case I should have “cut and paste” one more time, and it would have given me no trouble.
