The warning is self-descriptive - api expects format you're passing to stringByAppendingFormat function to be a string literal. To avoid this warning you can just append a string (as you don't use format parameters anyway):

cell.quantity.text = [quant stringByAppendingString:metricUnit];

or

cell.quantity.text = [quant stringByAppendingFormat:@"%@",metricUnit];
