Which works fine, but rapidly expands into a huge if-statement as you
try and handle more states. Ideally I'd like to do something along
the lines of:
NSMutableArray* ingredients = [NSMutableArray arrayWithObjects:@"gin",
@"vodka", nil];
if (user.likesTequila)
[ingredients addObject:@"tequila"];
[bartender mixCocktailIngredients:
NSArrayToVariableList(ingredients)];
How about something like this:
const int kMaxNumberOfIngredients = 50;
NSString* a[kMaxNumberOfIngredients];
// Zero out a
[ingredients getObjects:a]; // Assumes no more than 50 objects in
ingredients, will crash otherwise
[bartender mixCocktailIngredients: a[0], a[1], a[2] ..... a[48], a[49]];
A little clunky, but it should be usable if the max possible options
in known in advance and not excessive.
Also assumes that mixCocktailIngredients method really does check for
nil terminator instead of count of arguments
