ziparchive是基于开源代码”MiniZip”的zip压缩与解压的Objective-C 的Class,使用起来非常的简单
方法：从http://code.google.com/p/ziparchive/ 上下载ZipArchive.zip，解压后将代码加入工程中，并且把libz.dylib库添加到工程中
使用方法：
1. 压缩:ZipArchive可以压缩多个文件,只需要把文件一一addFileToZip即可.
- ZipArchive* zip = [[ZipArchive alloc] init];
- NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
- NSString *documentpath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
- NSString* l_zipfile = [documentpath stringByAppendingString:@"/test.zip"] ;
-
- NSString* image1 = [documentpath stringByAppendingString:@"/image1.jpg"] ;
- NSString* image2 = [documentpath stringByAppendingString:@"/image2.jpg"] ;
-
- BOOL ret = [zip CreateZipFile2:l_zipfile];
- ret = [zip addFileToZip:image1 newname:@"image1.jpg"];
- ret = [zip addFileToZip:image2 newname:@"image2.jpg"];
- if( ![zip CloseZipFile2] )
- {
- l_zipfile = @"";
- }
- [zip release];
2. 解压缩:
- ZipArchive* zip = [[ZipArchive alloc] init];
- NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
- NSString *documentpath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
-
- NSString* l_zipfile = [documentpath stringByAppendingString:@"/test.zip"] ;
- NSString* unzipto = [documentpath stringByAppendingString:@"/test"] ;
- if( [zip UnzipOpenFile:l_zipfile] )
- {
- BOOL ret = [zip UnzipFileTo:unzipto overWrite:YES];
- if( NO==ret )
- {
- }
- [zip UnzipCloseFile];
- }
- [zip release];
