Question

我正在尝试编写一些编辑二进制plist文件的脚本。 plist描述了DVD studio pro文件中包含的对象。看起来DVD studio pro中的文本框在plist中编码为base64数据，用于描述文本字符串及其格式。我似乎无法弄清楚如何理解这些数据。理想情况下，我希望能够更改文本字符串，但不能更改格式。以下似乎描述了一个文本框，上面写着“菜单标题”。有两个字符串，一个字符串称为“字典”，另一个字符串称为“字符串”;两者都是CFData。有什么想法我可以解析这个或将其转换为我可以直接编辑的格式？我一直在玩可可，但是没有运气。

这是一个base64编码的NSArchiver存档。您需要先解码base64，然后使用[NSUnarchiver unarchiveObjectWithData:]。上面的“Dictionary”条目在解码后看起来像这样（在Python语法中，因为我使用了pyObjC）：

{
    NSBackgroundColor = "NSCalibratedWhiteColorSpace 0 0";
    NSColor = "NSCalibratedRGBColorSpace 0.94902 0.937255 0.921569 1";
    NSExpansion = "0.1053606";
    NSFont = "\"LucidaGrande 21.00 pt. P [] (0x103110b60) fobj=0x103110c30, spc=6.64\"";
    NSObliqueness = 0;
    NSParagraphStyle = "Alignment 0, LineSpacing 0, ParagraphSpacing 0, ParagraphSpacingBefore 0, HeadIndent 0, TailIndent 0, FirstLineHeadIndent 0, LineHeight 0/0, LineHeightMultiple 0, LineBreakMode 0, Tabs (\n    28L,\n    56L,\n    84L,\n    112L,\n    140L,\n    168L,\n    196L,\n    224L,\n    252L,\n    280L,\n    308L,\n    336L\n), DefaultTabInterval 0, Blocks (null), Lists (null), BaseWritingDirection -1, HyphenationFactor 0, TighteningFactor 0.05, HeaderLevel 0";
}
