我如何检查CLLocationCoordinate2D是否在四个CLLocationCoordinate2D Square内？在Objective C中使用Google地图 [英] How can I check if a CLLocationCoordinate2D is inside four CLLocationCoordinate2D Square? in Objective C with Google Maps

问题描述

我想测试一个CLLocationCoordinate2D是否在由其他四个CLLocationCoordinate2D创建的Square中我有这样一个结构：

  typedef struct {
 CLLocationCoordinate2D southWest; 
 CLLocationCoordinate2D southEast; 
 CLLocationCoordinate2D northEast; 
 CLLocationCoordinate2D northWest; 
}界限; 
  

以参数形式传递CLLocationCoordinate2D坐标。我想测试坐标是否在边界内。

   - （BOOL）isCoordinate：（CLLocationCoordinate2D）coordinate insideBounds：（Bounds）bounds {... } 
  

解决方案

如果你有四点，你可以制作CGRect并使用CGRectContainsPoint（）

I want to test if a CLLocationCoordinate2D is inside a Square created from other four CLLocationCoordinate2D

I have a struct like this:

typedef struct {
    CLLocationCoordinate2D southWest;
    CLLocationCoordinate2D southEast;
    CLLocationCoordinate2D northEast;
    CLLocationCoordinate2D northWest;
} Bounds;

And a CLLocationCoordinate2D coordinate passed as param. And I want to test if coordinate is inside the Bounds. How can I test that?

- (BOOL) isCoordinate:(CLLocationCoordinate2D)coordinate insideBounds:(Bounds)bounds { ... }

解决方案

If you have four points you can make a CGRect and use CGRectContainsPoint()
