Hi Nimesh
Thanks for your reply & I've got it to work now as follows:
// Create AGSUniqueValue objects
AGSUniqueValue *stn = [[AGSUniqueValue alloc] initWithValue:@"STN" label:nil description:nil symbol:composite];
Another query: What is the 'label' in the above statement used for? Thought it's for 'labelling' the symbol as what I had wanted to do. Also, how is the 'description' being used?
Thanks.
