推荐答案

您是否只想将字符串保存到磁盘？我会使用NSCoding。

Do you just want to save the string to the disk? I would use NSCoding for that.

将对象写入文件：

result = [NSKeyedArchiver archiveRootObject:attributedString toFile:archivePath];

从文件中读取对象：

attributedString = [NSKeyedUnarchiver unarchiveObjectWithFile:archivePath];

您可以使用符合NSCoding的任何对象执行此操作，并且可以非常轻松地添加对NSCoding到您自己的课程。有关更多信息，请访问：

You can do this with any object conforming to "NSCoding", and it's fairly easy to add support for NSCoding to your own classes. More information can be found at:
