    Here small snippet for UITextFieldDelegate:

    -(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
        if([[textField text] length] > 0) {
            if([[textField text] characterAtIndex:([[textField text] length]-1)] == ' ' && 
               [string isEqualToString:@" "]) return NO;
        }
        return YES;
    }
