你如何在IOS 5中加入SSZipArchive？ [英] How do you include SSZipArchive for IOS 5?
问题描述
对于我正在处理的项目，我需要解压缩某些文件。为此，我找到了图书馆 SSZipArchive 。我将其包含在Xcode 4.2中（右键单击Classes文件夹 - >将文件添加到项目中，在对话框中将将项目复制到目标组的文件夹中 - 选中复选框）。我包含了libz库（我已经尝试了libz和zlib1.2.5）。我尝试编译，突然间我遇到了20个错误：
For the project I'm working on I needed to unzip certain files. For this, I found the library SSZipArchive. I included this in Xcode 4.2 (Right-click on the Classes folder->Add files to project, with in the dialogue the "Copy items into destination group's folder"-checkbox checked). I include the libz library (I've tried both libz and zlib1.2.5). I try to compile and suddenly I've got 20 errors:

这些都是核心库中的错误，所以在Xcode中包含库可能会出错。我设法将罪魁祸首缩小到SSZipArchive使用的minizip库（如果我删除该库，错误消失，编译器就像应该的那样运行），但我很难理解为什么这会导致编译器出现这么多问题。
These are all errors in the core library, so probably something went wrong with including the library in Xcode. I managed to narrow down the culprit to the minizip library that SSZipArchive uses (if I remove that library, the errors disappear and the compiler runs like it should), but I'm pretty stumped on why this causes the compiler to have so many issues.
推荐答案
经历了很多麻烦之后，我发现了问题所在。原来是_Prefix.pch。我完全看了看，但事实证明我在那里有以下一行：
After a lot of headaches, I figured out what was the problem. It turned out to be _Prefix.pch. I totally looked over it, but it turns out that I had the following line there:
#import "someclass.h"
此类正在使用minizip库的.c文件加载，从而生成Objective-C标题包含在.c文件中，这是XCode不喜欢的。将这些语句包装在#ifdef语句中修复了问题：
This class was being loaded in with the .c-files of the minizip library, resulting in Objective-C headers being included in .c-files, which was something that XCode did not like. Wrapping these statements in an #ifdef statement fixed the problem:
#ifdef __OBJC__
#import "someclass.h"
#endif
