我必须使用谷歌地图为我的iPhone项目,我使用GMSpolygon绘制多边形但我怎么能填充我的地图上的任何地方,除了多边形的内部.如下图所示.
谢谢.
解决方法
-(void) drawsamplepolygon { GMSpolygon *polygon = [[GMSpolygon alloc] init]; polygon.path = [self pathOfNewYorkState]; polygon.title = @"New York"; polygon.fillColor = [UIColor colorWithRed:0.25 green:0 blue:0 alpha:0.2f];
