本文介绍了一种针对iOS应用中特定页面（如话题详情页）的导航控制器进行优化的方法，通过判断当前可见视图控制器类型并采取不同措施来提高页面加载效率。包括直接刷新页面内容及调整导航堆栈。

if([delete_navigation.visibleViewController isKindOfClass:[TopicViewController class]] && [topicNotification.topic.id isEqualToString:self.otherTopicID]){//判断本身就在当前页时只需刷新即可
           
            TopicViewController *controller=(TopicViewController *)delete_navigation.visibleViewController;
            controller.topicNotification=topicNotification;
            controller.topicId=topicNotification.topic.id;
            [controller refreshTopic];
        }else{
            TopicViewController *controller= [[TopicViewController alloc] initWithNibName:@"TopicViewController" bundle:nil];
            controller.topicNotification=topicNotification;
             controller.topicId=topicNotification.topic.id;
            
            if([delete_navigation.topViewController isKindOfClass:[TopicViewController class]]){
                
                NSMutableArray *navigationArray = [[NSMutableArray alloc] initWithArray: delete_navigation.viewControllers];
                
                // [navigationArray removeAllObjects];    // This is just for remove all view controller from navigation stack.
                [navigationArray removeLastObject];  // You can pass your index here
                delete_navigation.viewControllers = navigationArray;
            }
            
            [delete_navigation pushViewController:controller animated:YES];
            
        }

这是程序代码，要根据自己的情况删除调整
