NSString *trimmedString = [string stringByTrimmingCharactersInSet:
                                  [NSCharacterSet whitespaceAndNewlineCharacterSet]];

From Cocoanetics...

Take a look at the NSString method stringByReplacingOccurrencesOfString:withString for example, this should be able to perform the basic task you want it to do.
