I know i am doing something wrong , dont know where though , i want individual images for legend but its not coming and its crashing the app

+ (AGLegendInfo*)infoForGraphicsLayer:(AGSGraphicsLayer*)layer

{

AGLegendInfo *legendInfo = [[AGLegendInfo alloc] init];

NSMutableArray *legendInfos = [[NSMutableArray alloc] init];

AGSRenderer *renderer = layer.renderer;

AGLegendInfoType *info = [[AGLegendInfoType alloc] init];

AGSGraphic *g = [[AGSGraphic alloc]init];

UIImage *image = [[UIImage alloc]init];

if ([layer.renderer isKindOfClass:[AGSUniqueValueRenderer class]])

{

NSLog(@"AGSUniqueValueRenderer");

AGSUniqueValueRenderer *renderer = (AGSUniqueValueRenderer *)layer.renderer;

int num = [renderer.uniqueValues count];

NSLog(@"%d", num);

for (int j = 0 ; j < num ; j++)

{

AGSUniqueValue *value = [renderer.uniqueValues objectAtIndex:j];

g = [layer.graphics objectAtIndex:j];

image = [renderer swatchForFeature:g size:CGSizeMake(20, 30)];

legendInfo.defaultSymbol = image;

[legendInfos addObject:legendInfo];

}

//[legendInfos addObject:legendInfo];

legendInfo.defaultSymbol = image;

legendInfo.layerName = layer.name;

legendInfo.types = [[NSArray alloc] initWithArray:legendInfos];

return legendInfo;

}

I see you are using AGLegendInfo class. Is that meant to be AGSLegendInfo?

Which version of the SDK are you using (or intend to use)? I ask because AGSLegendInfo class is present only in the Quartz beta release and AGSGraphicLayer is in 10.2.5 (AGSGraphicsOverlay in Quartz)

no its not AGSLegendinfo , I have create my own class. the issue is the

render does not send all the types in.

but requirement has change now as users want those render values as a layer

that they can turn on and off

So I have to create individual layers for those render value. you may

solve my other issue , can i create a dynamic variable for

AGSGraphicsLayer

like i have to create all these AGSGraphicsLayer with different type of

statuses

AGSGraphicsLayer* APPRmyGraphicsLayer = [AGSGraphicsLayer

graphicsLayer];

AGSGraphicsLayer* COMPmyGraphicsLayer = [AGSGraphicsLayer

graphicsLayer]; ... and so on

why i cant do something like

NSSet *uniqueStatus = [NSSet setWithArray:[objects valueForKey:@"status"

]];

int numElement = uniqueStatus.count;

NSMutableArray *gr = [[AGSGraphicsLayer alloc]init];

for (NSString *item in uniqueStatus) {

;

}

for (NSString *item in uniqueStatus)

{

AGSGraphicsLayer *gr = [[AGSGraphicsLayer alloc] init];

;

NSLog(gr.name);

}

both gives me an error , the layer gets added to map but i cant add

geometry to it as its not an unique name layers

Please send a sample project that would reproduce the issue so we can take a look.
