I am an Objective C newbie. I want to write a method that takes in an array of strings and returns a concatenated string, with a comma (,) in between each string. So if an array is {a b c d}, I want to return a,b,c,d.
我是一个客观的菜鸟。我想编写一个方法，它接收一个字符串数组并返回一个连接的字符串，每个字符串之间都有一个逗号(，)。如果一个数组是{a b c d}，我想返回a b c d。
What is the easiest way to do that?
