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.

I am working on a project using a MapView based on @jsbain "Map View Demo2.py" jsbain github

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

'''

That did the trick.
selfupdate was successfull.

"pip install pythonista-gestures" installed the first time.

StaSh v0.7.2 on python 3.6.1
pythonista V. 3.4 (330025)
iphone 6S+
iOS 13.3.1
StaSh "selfupdate" returns "Already at latest version"

I've tried this over the last couple of days. Restarted Pythonista, rebooted iphone, etc. with the same result.

I tried pip install again with the above "extras", no joy, results below.

wget from the site-packages directory worked fine.
time to play with my new ̶t̶o̶y̶s̶ tools

This looks great! But I can't seem to get the install to work. This is what I get:
