Xcode gives Apple Mach-O linker error
提问by kuranes
I just compiled a project and Xcode returns these two errors which don't seem to be my code's fault. How do I fix them?
我刚刚编译了一个项目，Xcode 返回了这两个错误，这似乎不是我的代码的错。我该如何修复它们？
Undefined symbols for architecture i386:
"_vImageBoxConvolve_ARGB8888", referenced from:
-[UIImage(Blur) boxblurImageWithBlur:] in UIImage+Blur.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

教男人（或女人）钓鱼：
Usually Mach-O Linker Error means you have not included a header file for a function you are using in your code.
通常 Mach-O 链接器错误意味着您没有在代码中包含您正在使用的函数的头文件。
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):
最简单的方法是使用 shift+command+O 复制该函数或方法调用并粘贴到 Xcode 快速搜索中。这将搜索所有框架（和头文件），找到该函数或方法调用并显示其位置（在本例中为头文件）：
In this case, this call belongs to the Accelerate framework so on top of your file, enter:
在这种情况下，此调用属于 Accelerate 框架，因此在您的文件顶部，输入：
#import <Accelerate/Accelerate.h>
When doing quick search, you might have to get rid of leading underscore. In other words, search for vImageBoxConvolve_ARGB8888
在进行快速搜索时，您可能需要去掉前导下划线。换句话说，搜索 vImageBoxConvolve_ARGB8888
Hope this helps
希望这可以帮助

Google is your friend: someone else fixed this by adding the Accelerate framework to their project (and this does look like a framework error).
Google 是你的朋友：其他人通过将 Accelerate 框架添加到他们的项目中来解决这个问题（这看起来确实是一个框架错误）。

Make sure you also have the QuartzCore framework included as well, as that is also required by that library.
确保您还包含 QuartzCore 框架，因为该库也需要。

Apparently vImageBoxConvolve_ARGB8888() is not defined. See if the Accelerate framework is properly included in the project.
显然 vImageBoxConvolve_ARGB8888() 没有定义。查看 Accelerate 框架是否正确包含在项目中。
