ios - MKMapView. create a path on the move -

-

i trying create line on mkmapview after users path.

i've found rather old post, , i'm trying make work explained in accepted answer:

does have examples on how create path using mkoverlaypathview?

what don't how "extract" array of cllocation objects mentioned. right have set mapview setshowsuserlocations:yes, , updates movement fine, guess can cllocations objects somehow, , continuously draw line?
