iOS边练边学--文件压缩和解压缩的第三方框架SSZipArchive的简单使用

一、非cocoaPods方法，需要注意的是：直接将SSZipArchive拖入项目编译会报错。

Undefined symbols for architecture x86_64:

"_crc32", referenced from:

_unzReadCurrentFile in unzip.o

_zipWriteInFileInZip in zip.o

"_deflate", referenced from:

_zipWriteInFileInZip in zip.o

_zipCloseFileInZipRaw64 in zip.o

"_deflateEnd", referenced from:

"_deflateInit2_", referenced from:

_zipOpenNewFileInZip4_64 in zip.o

"_inflate", referenced from:

"_inflateEnd", referenced from:

"_inflateInit2_", referenced from:

_unzOpenCurrentFile3 in unzip.o

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

将框架拖入项目，还需要引入另一个资源包。如图：

二、利用cocoaPods导入的SSZipArchive则不需要导入任何资源包，因为系统已经帮我们做好了。代码示例：
