如何将NSTextView的格式化内容转换为字符串 [英] How to convert formatted content of NSTextView to string

问题描述

我需要将NSTextView的内容从Mac应用程序传输到iOS应用程序。我使用XML作为传输的文件格式。

I need transfer content of NSTextView from Mac app to iOS app. I'm using XML as transfered file format.

因此，我需要将NSTextView的内容（文本，字体，颜色atd。）保存为字符串。有什么办法怎么办？

So I need to save content of NSTextView (text, fonts, colors atd.) as a string. Is there any way how to do that?

推荐答案

一种方法是归档NSAttributedString值。大纲示例代码直接键入回答：

One way to do this is to archive the NSAttributedString value. Outline sample code typed directly into answer:

NSTextView *myTextView;
NSString *myFilename;
...
[NSKeyedarchiver archiveRootObject:myTextStorage.textStorage
                            toFile:myFilename];

回读：

myTextView.textStorage.attributedString = [NSKeyedUnarchiver unarchiveObjectWithFile:myFilename];

这就是创建和读回文件所需要的。有匹配的方法创建一个NSData而不是一个文件，你可以将NSData转换为NSString或只是插入一个NSDictionary和serialise作为plist（XML）等。

That's all that is needed to create and read back a file. There are matching methods which create an NSData rather than a file, and you can convert an NSData into an NSString or just insert one into an NSDictionary and serialise that as a plist (XML), etc.
