Hello Guys.. I have an NSString named word (as you can guess, its one word), I don't know the length of the string. I need to check if the last letter (and only the last), Contains the sign "?" or "!", or any other sign that is not A-Z, a-z or 1-9. If the sign is not A-Z, a-z, or 1-9, than the sign will be erased from the string. Exsample: hello! = hello. Please just help me find the command for doing that, I'm looking for it for a long time now.. Hope you will answer me as soon as possible. Tal Shani.
