Populate an Array with a Comma Delimited String Content?

Question

My app uses a web service in which you scan a food item which returns a UPC number. I feed this number into the web service, and i get all the details about that specific food. I grabbed the "ingredients" and turned it into an array called "ingredients".

This is the value of my array:

  ingredientsArray = dataDictionary[@"nf_ingredient_statement"];

When I NSLog my [ingredients description] value, it looks like this:

Distilled Vinegar, Water, #1 Grade Mustard Seed, Salt, Turmeric, Paprika, Spice, Natural Flavors and Garlic Powder.

My question is how can I turn that string into an array which will populate the table view?

i used the web service to turn the returned value of "ingredients" into an array — doc92606

IF you want to turn a comma-separated string into an array, here is how you do it, assuming the string is separated by a comma and then a space.

NSString *exampleString = @"one, two, three";
NSArray *exampleArray = [exampleString componentsSeparatedByString:@", "];

Produces:

    one,
    two,
    three
)

I'm not confident based on your post/comment if you're dealing with an array or a string, but if I were you I would NSLog(@"%@", [ingredientsArray class]); to see what class the object you think you have is.
