[RTCImageTiledLayer tiledSublayers]: unrecognized selector under 100.2.1

mh10 — Mon, 04 Jun 2018 18:08:40 GMT

After upgrading from 100.1 to 100.2.1 our existing code is now failing when trying to call AGSArcGISTiledLayer initWithTileInfo

@interface TileLayer : AGSArcGISTiledLayer

self = [super initWithTileInfo:tileInfo fullExtent:envelope];

get error:
[RTCImageTiledLayer tiledSublayers]: unrecognized selector sent to instance 0x11baeea10

Could you provide some more info please so we can try to reproduce this?

For example, what are the tileInfo and fullExtent parameters, or does it occur across a range of values?

I haven't tried any other values

int resolutionLevels = 20;

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

for (int i=0; i < resolutionLevels;i++)
{
double resolution = 156543.032 / pow(2,i);
double scale = 5.91657527591555E8 / pow(2,i);

[levelsOfDetail addObject:[AGSLevelOfDetail levelOfDetailWithLevel:i resolution:resolution scale:scale]];
}

AGSPoint *origin = [AGSPoint pointWithX:-20037508.342787 y:20037508.342787 spatialReference:AGSSpatialReference.webMercator];

AGSEnvelope *envelope = [AGSEnvelope envelopeWithXMin:-20037507.0671618 yMin:-19971868.8804086 xMax:20037507.0671618 yMax:19971868.8804086 spatialReference:AGSSpatialReference.webMercator];

AGSTileInfo *tileInfo = [AGSTileInfo tileInfoWithDPI:96
format:AGSTileImageFormatPNG32
levelsOfDetail:levelsOfDetail
origin:origin
spatialReference:AGSSpatialReference.webMercator
tileHeight:256
tileWidth:256];

self = [super initWithTileInfo:tileInfo
fullExtent:envelope];

Thanks. I'm able to reproduce this here. We'll look into it.

Would you be able to subclass from AGSImageTiledLayer instead, or is there specific AGSArcGISTiledLayer functionality that you need?

Hi m h‌,

Were you able to get this working by inheriting from AGSImageTiledLayer?

Nick.

Sorry didn't see your replies, just tried switching to AGSImageTiledLayer and it works ok, we weren't using anything in AGSArcGISTiledLayer.

thanks a lot!
