evanlong / PhantomLines.m
Created February 3, 2011 00:57
Phantom lines appear on either the zero latitude or longitude axis if a point's latitude or longitudes settings are zero. Since both are zero in this case it will appear on both. This only occurs if the line width for the polyline is <= 1.
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
CLLocationCoordinate2D points[2];
points[0].latitude = 0;
points[0].longitude = 0;
points[1].latitude = -6;
points[1].longitude = 5;
MKPolyline* polyline = [MKPolyline polylineWithCoordinates:points count:2];
