Hi folks. Just got back from a trip but I thought I would write you and tell you about this thing.
Sometimes, you just want to concatenate a bunch of strings together. There are several ways to do this. You can use stringByAppendingFormat with NSStrings or you can use append with NSMutableStrings. You can also add a bunch of strings to an array and generate a new string based on the array. Some languages overload the “+” operator to allow strings to be added together. Since Objective-C is a strict superset of C we can’t overload that operator.
So, what I’ve done is simply create a category on the NSString class. It contains a single class method called “concatenateStrings” that takes any number of arguments. Any number of NSString or NSMutableString arguments are concatenated together and returned as an NSString.
