What is the most efficient way to count number of word in NSString without using regex?

Question

I am a bit new to Objective C and was wondering if there is a better way to count words in a string.

ie:

NSString *str = @\"this is a string\";

// r         


        

Answer 1

This code will count the number of words (i.e., non-empty substrings) contained in a string that are separated by any number of space or line break characters:

NSUInteger wordCount = 0;

for (NSString* word in [someString
    componentsSeparatedByCharactersInSet:
    [NSMutableCharacterSet characterSetWithCharactersInString:@" \n"]]) {

    if (![word  isEqual: @""]) {
        wordCount++;
    }

}

It's a slight improvement to zoul's answer without recurring to regexes.
