MKPolygon to cover entire earth

问题

I'm trying to create an MKPolygon that will cover the entire earth, but can't find the right coordinates.

my code looks like this:

CLLocationCoordinate2D pathCoords[5]={
    CLLocationCoordinate2DMake(0,-90),
    CLLocationCoordinate2DMake(0,90),
    CLLocationCoordinate2DMake(-180,90),
    CLLocationCoordinate2DMake(180,-90),
    CLLocationCoordinate2DMake(0,-90),
};

MKPolygon *result = [MKPolygon polygonWithCoordinates:pathCoords count:5];

I've found this article that can help: http://www-01.ibm.com/support/knowledgecenter/SSEPGG_9.5.0/com.ibm.db2.luw.spatial.topics.doc/doc/geodnew1039296.html

But using those coordinated yields totaly different results in mapKit.

Can anyone help?

回答1:

For anyone interested, Anna was right, the code that solves the problem:

CLLocationCoordinate2D worldCoords[6] = { {90, 0}, {90, 180}, {-90,180}, {-90,0}, {-90,-180}, {90,-180} };
