Objective c - insert character into string between certain characters

Question

I need to insert a character into a string between each occurrence of strings that I have in an array. For example:

array = [ab,bc,cd,de];
string = @"abbccd";

newString = @"ab*bc*cd";

How can I accomplish this? I looked around but couldn't find a good solution. Thanks.

How about,

NSString *newString = [array componentsJoinedByString:@"*"];
