基于可可文档的应用，NSWindowController子类为“主窗口".

问题描述

我有一个基于Cocoa文档的应用程序.我希望主窗口"由我的NSWindowController子类管理.我已经创建了子类，并将其接口布置在具有相同名称的.xib文件中.我最终希望获得与NSDocument管理窗口相同的行为，而由NSWindowController管理该窗口.

I have a Cocoa document based app. I want the "main window" to be managed by my subclass of NSWindowController. I have created the subclass and laid out its interface in a .xib file with the same name. I ultimately want the same behaviour as if the NSDocument managed the window, but instead have it managed by an NSWindowController.

首先，我该怎么做?其次，使用这种方法时，我有什么特别需要考虑的事情，例如如何处理打开和保存?

First of all, how do I do it? Second, are the anything special I have to think about when going with this approach, such as how to handle open and save?

推荐答案

1. 使用您自己的windowController实例覆盖makeWindowControllers

1. Override makeWindowControllers with your own windowController instance

//Lazy instantiation of window controller
- (WindowController *)controller {
  if (!_controller) {
      _controller = [[WindowController alloc] initWithWindowNibName:@"Document"];
  }

  return _controller;
}

- (void)makeWindowControllers {
  [self addWindowController:self.controller];
}

评论窗口NibName& windowControllerDidLoadNib:aController方法

comment windowNibName & windowControllerDidLoadNib:aController methods

//- (NSString *)windowNibName
//{
//  // Override returning the nib file name of the document
//  // If you need to use a subclass of NSWindowController or if your document supports multiple NSWindowControllers, you should remove this method and override -makeWindowControllers instead.
//  return @"Document";
//}

//- (void)windowControllerDidLoadNib:(NSWindowController *)aController
//{
//  [super windowControllerDidLoadNib:aController];
//  // Add any code here that needs to be executed once the windowController has loaded the document's window.
//}

将Document.xib文件所有者类从NSDocument更改为WindowController

Change Document.xib File Owner Class from NSDocument to your WindowController

您可以从WindowController中向文档类发送一条消息(调用方法).

From your WindowController you can send a message (call method) to your document class.
