当我崩溃时，请看下面的方法

 + (NSArray*) controllersByTitle:(NSString*)title andNavigationController:(UINavigationController*)navController andSideBarController:(SP2SideBarViewController *)sidebarViewController {
    if ( [title isEqualToString:NSLocalizedString(@"****", @"****")] ) {
        **** *controller;

        controller.leftSidebarViewController  = sidebarViewController;
        sidebarViewController.sidebarDelegate = controller;
        return [NSArray arrayWithObject:controller];
    }
    else if ( [title isEqualToString:NSLocalizedString(@"****", @"****")] ) {
