Hi,

I have my current location from CLLocation,

and I have another location- also an CLLocation.

I would like to detect when my device is heading towards that other location.

(I can calculate the distance in meters between this points- but can't workout

the calculation of an accurate angle to compare with the device current heading)

Thanks.
