localize UIAlertView

In my app, I'm using a lot of UIAlertView, so I need to localize every string I use. The below is my way to localize UIAlertView. But I got an exception which says " [__NSArrayM insertObject:atIndex:]: object cannot be nil' " After looking into it, I believe it's otherButtonTitles causing this exception whenever I try to localize otherMessage. If I just assign nil to "otherButtonTitles", everything works OK! But I'm still not sure how can I fix it if I want to localize it, and why this causes exception.

Thank you

- (void)showAlertWithTitle:(NSString *)title message:(NSString *)aMessage delegate:(id)delegate cancelMessage:(NSString *)aCancelMessage otherMessage:(NSString*)otherMessage{

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle: NSLocalizedString(title, nil)
message: NSLocalizedString(aMessage, nil)
delegate: delegate
cancelButtonTitle: NSLocalizedString(aCancelMessage, nil)
otherButtonTitles: NSLocalizedString(otherMessage, nil), nil];
    [alertView show];
}

You can use the addButtonWithTitle: method of the UIAlertView and before use you can check the value of the otherMessage parameter.

See below the solution:

- (void)showAlertWithTitle:(NSString *)title message:(NSString *)aMessage delegate:(id)delegate cancelMessage:(NSString *)aCancelMessage otherMessage:(NSString*)otherMessage {
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle: NSLocalizedString(title, nil)
                                                        message: NSLocalizedString(aMessage, nil)
                                                       delegate: delegate
                                              cancelButtonTitle: NSLocalizedString(aCancelMessage, nil)
                                              otherButtonTitles: nil];
    if (otherMessage != nil) {
        [alertView addButtonWithTitle:NSLocalizedString(otherMessage, nil)];
    }    
    [alertView show];
}
