userLocation: latitude/longitude return zero?

Question

I am just looking at mapKit and decided to make a quick button to display my current location, however when I press the button my latitude/longitude always display as [0.000000]

Answer 1

Either the userLocation is not visible on the map (see the userLocationVisible property) or there is some problem setting up the myMapView property and it's nil (i.e. not connected in interface builder)
