Question

I have seen one answer for my task, but I couldnt find it now.
I want to detect whether a string has empty word and contains at least “” or ” ” (two spaces” or more multiple spaces, OR not.
If not, I would add this to Nsmutablearray.
If yes with empty or at least one space, I would like it not to be written to mutablearray.

How to solve this?

EDIT 12 October 2011:

Guys, thank you.

Again I am sorry that I was unclear about my wish. I wanted to check if a string is empty or contains whitespaces without any character. I have posted my answer below.

Answer 1

    if( bookmarked.length == 0 )
    {
        NSLog (@"not allowed: empty");

    } 
    else if ([[bookmarked stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] length] == 0)        
    { 
        NSLog (@"not allowed: whitespace(s)");
    }

    else 
    {
        [bookmarklist addObject:bookmarked];
    }
