GLMapVectorCascadeStyle

Objective-C


@interface GLMapVectorCascadeStyle : NSObject

Swift

class GLMapVectorCascadeStyle : NSObject

GLMapVectorCascadeStyle is used to define appearance of GLMapVectorObject. One style could be used with many GLMapVectorObjects. Style is used to render a map, which is stored inside DefaultStyle.bundle/Style.mapcss. Detailed MapCSS specification is located at: http://www.mapcss.org MapCSS examples: Any point with tag natural=peak, should be displayed on zoom level 11+ with trangle icon tinted with brown color.

node|z11-[natural=peak] {
icon-image:"triangle.svg";
icon-tint:brown;
}

Any point with tag natural=peak, should display it’s localized name on zoom level 13+.

node|z13-[natural=peak] {
text: eval( locTag('name') );
text-color:brown;
font-size:12;
}
