objective c - iOS default region span for tracking -


i setting map view centered device current location. wonder what's default (or conventional) span size showing kind of view? specifically

region.center.latitude = userlocation.coordinate.latitude; region.center.longitude = userlocation.coordinate.longitude; region.span.latitudedelta = ? region.span.longitudedelta = ?

is there default values ios map app uses? thanks!

the default span i'm pretty sure equal 0.05. instance:

float spanx = 0.05f; float spany = 0.05f;
