In my app i add array of AGSFeatureLayer with function:

for(int i=0;i<[self.nome count];i++){

                        NSString *url = [NSString stringWithFormat:@"%@/%i",servizio, i];

                        self.ServizioSITR = [AGSFeatureLayer featureServiceLayerWithURL:[NSURL URLWithString:url] mode:AGSFeatureLayerModeSnapshot];

                        [self.mapView addMapLayer:self.ServizioSITR withName:[self.nome objectAtIndex:i]];

}

I can not remove with function:

for(int i=0;i<[self.nome count];i++){

                    [self.mapView removeMapLayerWithName:[self.nome objectAtIndex:i]];

}

WHYYYYYYYYYYYY?

Please Help me

I would make 2  changes in your code.

for(int i=0;i<[self.nome count];i++){

                        NSString *url = [NSString stringWithFormat:@"%@/%i",servizio, i];

                        AGSFeatureLayer *local = [AGSFeatureLayer featureServiceLayerWithURL:[NSURL URLWithString:url] mode:AGSFeatureLayerModeSnapshot];

                        [self.mapView addMapLayer:local withName:[self.nomeobjectAtIndex:i]];

}

Then I would let them all load before calling the method to remove them by name, as what I think is happening, you call remove layer with name and hasn't been loaded yet.

Let me know if that makes any difference.

Cheers
