MKPolygon覆盖整个地球 [英] MKPolygon to cover entire earth

问题描述

我正在尝试创建一个MKPolygon，它将覆盖整个地球，但是找不到正确的坐标.

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

我的代码如下:

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];

我发现这篇文章可以提供帮助:

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

但是使用这些协调产生的结果在mapKit中完全不同.

But using those coordinated yields totaly different results in mapKit.

任何人都可以帮忙吗?

推荐答案

对于任何有兴趣的人， Anna 是正确的，可以解决问题的代码:

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} };
