使用 ZipArchive 时，Xcode 报错 Apple Mach-O Linker (ld) Error Group，错误原因是类库依赖的框架没有添加，添加缺失的框架即可，在这个例子中我添加了 libe.tbd 后解决。
Teaching a man (or women) how to fish:
Usually Mach-O Linker Error means you have not included a header file for a function you are using in your code.
Easiest way is to copy that function or method call and paste into Xcode quick search using shift+command+O. This will search all frameworks (and header files), find that function or method call and show you its location (the header in this case):
In this case, this call belongs to the Accelerate framework so on top of your file, enter
#import <Accelerate/Accelerate.h>.When doing quick search, you might have to get rid of leading underscore. In other words, search for vImageBoxConvolve_ARGB8888
Hope this helps
