objective-c - 用于 TAR 归档和取消归档文件的 Cocoa 类

Question

有人围绕文件的 tar 归档/取消归档编写了一个简单的 Cocoa 包装类吗？

我打算自己做这件事，除非有人已经慷慨地做到了。

编辑:有什么原因我不应该只围绕“tar”终端命令编写包装类吗？ (通过 NSTask)？除非有人反对，这就是我现在打算做的。

在您自己执行此操作(至少是取消存档)之前，我建议您查看 The Unarchiver的来源。
它支持Zip、Tar-GZip、Tar-BZip2、RAR、7-zip、LhA、StuffIt等。

对于完整的归档/取消归档支持，还有libarchive，
这是 BSD 许可并用 C 编写:http://code.google.com/p/libarchive/
(甚至还有一个 libarchive 的 static library 分支用于 iOS)

Filter Support

• gzip (read and write, uses zlib)
• bzip2 (read and write, uses bzlib)
• compress (read and write, uses an internal implementation)
• uudecode (read only)
• separate command-line compressors with fixed-signature auto-detection
• xz and lzma (read and write using liblzma)
• lzma (if you lack liblzma, you can get read-only lzma support through the lzmadec library; this will likely be dropped as soon as liblzma is stable and widely-available)
• Starting with libarchive 2.7, most of the above will fall back to using command-line tools if the libraries were unavailable at build time. Note that the command-line tools are usually slower than using the libraries directly.

Archive Formats Supported

• tar (read and write, including GNU extensions)
• pax (read and write, including GNU and star extensions)
• cpio (read and write, including odc and newc variants)
• ISO9660 (read only, including Joliet and Rockridge extensions, with some limitations; write support starting with libarchive 2.9)
• Zip (read only, with some limitations, uses zlib; write support starting with libarchive 2.8)
• mtree (read and write, uses OpenSSL libraries for creating and verifying cryptographic hashes)
• shar (write only)
• ar (read and write, including BSD and GNU/SysV variants)
• empty (read only; in particular, note that no other format will accept an empty file)
• raw (read only, starting in libarchive 2.8)
• xar (read only, starting in libarchive 2.8)

仅供记录:Apple private API rejection with libarchive (顺便说一句，问题已解决)
