渲染一个面、一个区域，网上找到的代码是只是给出局部代码，缺少渲染符号，以及渲染符号的style，导致新手不能实现

本人使用具体代码如下，关键部分基本看出来

    AGSSimpleFillSymbol *MarkerSymbol =     [AGSSimpleFillSymbol simpleFillSymbol];    MarkerSymbol.color = [UIColor blueColor];    MarkerSymbol.style= AGSSimpleFillSymbolStyleSolid;    AGSMutablePolygon* poly = [[AGSMutablePolygon alloc] initWithSpatialReference:nil];    //添加环    [poly addRingToPolygon];    AGSPoint* points = [AGSPoint pointWithX:113 y:23 spatialReference:[AGSSpatialReference spatialReferenceWithWKID:GPSMercator WKT:nil]];    //添加节点    [poly addPointToRing:[self mapPointChangeto:points TO:kWebMercator]];        [poly addPointToRing:[self mapPointChangeto:[AGSPoint pointWithX:113 y:20 spatialReference:[AGSSpatialReference spatialReferenceWithWKID:GPSMercator WKT:nil]] TO:kWebMercator]];    [poly addPointToRing:[self mapPointChangeto:[AGSPoint pointWithX:114 y:20 spatialReference:[AGSSpatialReference spatialReferenceWithWKID:GPSMercator WKT:nil]] TO:kWebMercator]];    [poly addPointToRing:[self mapPointChangeto:[AGSPoint pointWithX:114 y:23 spatialReference:[AGSSpatialReference spatialReferenceWithWKID:GPSMercator WKT:nil]] TO:kWebMercator]];    [poly addPointToRing:[self mapPointChangeto:[AGSPoint pointWithX:113 y:23 spatialReference:[AGSSpatialReference spatialReferenceWithWKID:GPSMercator WKT:nil]] TO:kWebMercator]];
