Remove characters from NSString?

Question

NSString *myString = @\"A B C D E F G\";

I want to remove the spaces, so the new string would be \"ABCDEFG\".

Answer 1

If you want to support more than one space at a time, or support any whitespace, you can do this:

NSString* noSpaces =
    [[myString componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]
                           componentsJoinedByString:@""];
