Objective-C: How to extract part of a String (e.g. start with '#')

Pretty simple, easy to understand version avoiding NSRange stuff:

NSArray * words = [string componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]; 
NSMutableArray * mutableWords = [NSMutableArray new];
for (NSString * word in words){
    if ([word length] > 1 && [word characterAtIndex:0] == '#'){
        NSString * editedWord = [word substringFromIndex:1];
        [mutableWords addObject:editedWord];
    }
}
