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];
