如何从数组中获取给定属性具有相同值的对象？

我正在编写新 iOS SSH 客户端的服务器列表部分，并且我有一个模型 RWServer 目前看起来像这样*：

@interface RWServer : NSObject <NSCoding> {
  NSString *_hostname;
  NSUInteger _port;
  NSString *_password;
}

@property(nonatomic, copy)   NSString *hostname;
@property(nonatomic, assign) NSUInteger port;
@property(nonatomic, copy)   NSString *password;

@end

在我的服务器列表控制器中，我有 -[< ;UITableView数据源> tableView:cellForRowAtIndexPath:] 方法如下：

// self.servers is an instance of NSArray
RWServer *server = [self.servers objectAtIndex:indexPath.row];
cell.textLabel.text = server.hostname;

问题是，当用户配置了多个主机名相同但端口号不同的服务器时，它们无法相互区分。为了解决这个问题，我想将端口号附加到标签的文本中，但我不知道如何检索数组中具有相同主机名的项目，所以有人可以帮助我吗？任何帮助表示赞赏。

I'm writing the servers list part of a new iOS SSH client, and I have a model RWServer which currently looks like this*:

@interface RWServer : NSObject <NSCoding> {
  NSString *_hostname;
  NSUInteger _port;
  NSString *_password;
}

@property(nonatomic, copy)   NSString *hostname;
@property(nonatomic, assign) NSUInteger port;
@property(nonatomic, copy)   NSString *password;

@end

In my servers list controller I have in the -[<UITableViewDataSource> tableView:cellForRowAtIndexPath:] method the following:

// self.servers is an instance of NSArray
RWServer *server = [self.servers objectAtIndex:indexPath.row];
cell.textLabel.text = server.hostname;

The problem is that when a user has configured multiple servers with the same hostname but a different port number, they cannot distinguish them from eachother. To solve this I want to append the port number to the label's text, but I don't know how to retrieve the items in the array that have the same hostname, so could anyone please help me with this? Any help is appreciated.
