Classification: Reproducible:Always
When using MKMapkit, if you set:
"MapView.userTrackingMode = MKUserTrackingModeFollowWithHeading"
and you also set a custom "MKMapCamera",
you will get MKUserTrackingModeFollowWithHeading overwrites your custom camera settings (pitch , altitude).
Even, if you turn on "setCamera animated:YES",the two conflicts and the animate perform completely wrong ,not showing your position, but a  place that in the middle of your MKCoordinateRegion and your current location.

Steps to Reproduce: the project please ,thank you :-)
2.the project -> MapViewController.m contains two code blocks that conflict, they are
self.HackMapView.userTrackingMode = MKUserTrackingModeFollowWithHeading
MKMapCamera *newCamera = [[HackMapView camera] copy];
        [newCamera setPitch:45.0];
        [newCamera setHeading:90.0];
        [newCamera setAltitude:500.0];
        [HackMapView setCamera:newCamera animated:YES];
they aim at two different function but they conflict, you can remove one of code blocks to see the result.

Expected Results:
the MKUserTrackingModeFollowWithHeading shouldn't overwrite my own mapcamera's settings, I mean, if I set TrackingMode to follow and I set a camera with pitch, the pitch should keep its degress even I moved around and map following my position.

Actual Results:
MKUserTrackingModeFollowWithHeading overwrites my custom map camera settings (pitch , altitude).
At first ,map camera did changed its pitch and altitude ,
but after MKMapview have my location from CLLocationManager , map goes to my location and when the map going animation done, map camera settings had changed to the default one.
OR EVEN, map not show my position ,but a  place that in the middle of your MKCoordinateRegion and your current location.
I think the "setCamera" and "MKUserTrackingModeFollowWithHeading" are both performing map transition animations ,"setCamera" aims at MKCoordinateRegion and "MKUserTrackingModeFollowWithHeading" at my current location ,so at last it shows a place in the middle of my MKCoordinateRegion and my current location.
