running this code: 

NSLog(@"%f", MKMetersBetweenMapPoints(MKMapPointMake(33.6523, -118.507), MKMapPointMake(34.516, -117.628)));

returns this:

0.015819

When the expected output should be ~136900. What am I doing wrong?

    It looks like you’re giving a regular latitude and longitude to MKMapPointMake(). An MKMapPoint contains and x and y value, not latitude and longitude.

    Use MKMapPointForCoordinate(myLocation) to convert your locations to map points, then give those to your MKMetersBetweenMapPoints() function.

    Or easier still, use -distanceFromLocation: with two CLLocation objects. It gives you back a distance in meters, taking into account the curvature of the earth.
