ios - 无法编译 Ziparchive 库 (iOS)

Question

我需要在我的 Xcode 项目中下载并解压一个文件， 我正在使用 Ziparchive ( https://code.google.com/p/ziparchive/downloads/detail?name=ZipArchive.zip) 来这样做，而不是按照下面的每一步我得到编译错误:

/Developer/AR/vuforia-sdk-ios-2-6-8/samples/ARDemo/minizip/ioapi.c:68:18: Redefinition of 'fopen_file_func' as different kind of symbol
/Developer/AR/vuforia-sdk-ios-2-6-8/samples/ARDemo/minizip/ioapi.c:68:35: Use of undeclared identifier 'opaque'
/Developer/AR/vuforia-sdk-ios-2-6-8/samples/ARDemo/minizip/ioapi.c:68:58: Expected ';' after top level declarator
/Developer/AR/vuforia-sdk-ios-2-6-8/samples/ARDemo/minizip/ioapi.c:72:1: Expected unqualified-id
/Developer/AR/vuforia-sdk-ios-2-6-8/samples/ARDemo/minizip/ioapi.c:90:17: Redefinition of 'fread_file_func' as different kind of symbol
Developer/AR/vuforia-sdk-ios-2-6-8/samples/ARDemo/minizip/ioapi.c:90:42: Use of undeclared identifier 'stream'; did you mean 'strcat'?
  Developer/AR/vuforia-sdk-ios-2-6-8/samples/ARDemo/minizip/ioapi.c:90:50: Use of undeclared identifier 'buf'
/Developer/AR/vuforia-sdk-ios-2-6-8/samples/ARDemo/minizip/ioapi.c:95:1: Expected unqualified-id

我不知道如何成功编译它，感谢任何帮助。

就我而言，这是因为我的前缀文件不正确。 它包括在“#ifdef OBJC” block 之外的 objective-c 导入 所以当所有类都是objecttive-C类时没有问题但是当我添加minizip的C类时它没有编译。

只需将前缀文件中的所有导入移动到 obj block 中，瞧!

#ifdef __OBJC__
    #import <Availability.h>
    #import <UIKit/UIKit.h>
    #import <Foundation/Foundation.h>
#endif

希望对你有帮助
