how can I convert string to an array with separator?

Question

I have a string in the following format

myString = \"cat+dog+cow\"

I need to store each string separated by + in to a array. Eg:

Answer 1

NSArray *lines = [string componentsSeparatedByString:@"-"];

The first value will be stored in 0th index of lines and second value will be stored in 1th index of lines..

Why not array?
