防止“退出时保存”可可文件申请退出时的对话 [英] Preventing the "Save on Exit" dialogue on exit of a Cocoa Document Application

问题描述

您好
我有一个正在构建的基于Cocoa文档的应用程序，它允许您打开单独的视图并与Webview组件进行交互。但是，无论何时与它进行交互，然后关闭应用程序，都会出现一条消息，提示：

Hi I have a Cocoa document based application that I have been building, that allows you to open seperate views and interact with a webview component. However, when ever you have interacted with it, and then go to close the application, a message comes down saying:

是否要保存您在其中所做的更改？文档无标题？
如果您不保存所做的更改，您的更改将丢失。

"Do you want to save the changes you made in the document "Untitled"? "Your changes will be lost if you don’t save them."

我希望当我的申请被提交时关闭，此消息不会显示。我不需要任何自动保存或保存选项。如何防止显示此消息并将其禁用？

I wish to make it that when my application is closed, this message is not shown. I do not need any auto-saves or saving options. How do I prevent this message been shown and disable it?

在此先感谢

Sam

推荐答案

最近我有我所做的就是将以下方法放在继承NSDocument的自定义文档类中：

Recently I had the exact same wish to prevent the save dialog from showing up. What I did is put the following method in my custom document class that inherits NSDocument

-(BOOL)isDocumentEdited {
    return NO;
}
