    Hy,

    I’m the author of MTLocation. Thanks for using it by the way!
    For this to work you have to make sure, that your MKMapView is a subview of your ViewController’s view (and not the view itself). Then you have to increase the frame of your mapView with a simple Pytaghoras – calculation: the width and height must be at least as big as the diagonal: sqrt(visibleWidth[320]^2 + visibleHeight[480-88]^2) = 506.

    So that means 

     mapView = [[MKMapView alloc] initWithFrame:CGRectMake(-100,-100,520,520)];

    Hope that helped, please consider upvoting if it fixed your problem.
