Objective C - How to concatenate an entire array of strings?

Question

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.

What is the easiest way to do that?

Answer 1

There are many ways to do it, the simplest being

[yourArray componentsJoinedByString: @","]

Answer 2

Use NSArray's componentsJoinedByString: method.

NSArray *strings = ...;
NSString *combined = [strings componentsJoinedByString:@","];
