从http://code.google.com/p/ziparchive/ 上下载ZipArchive.zip，解压后将代码加入工程中，把zlib库添加到工程中

压缩    ZipArchive* zip = [[ZipArchive alloc] init];            NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);   NSString *documentPath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;   NSString * zipFile = [dcoumentpath stringByAppendingString:@"/images.zip"] ;             NSString *image1 = [dcoumentpath stringByAppendingString:@"/犬夜叉.jpg"] ;       NSString *image2 = [dcoumentpath stringByAppendingString:@"/杀生丸.jpg"] ;                   BOOL result = [zip CreateZipFile2:zipFile];    result = [zip addFileToZip:image1 newname:@"犬夜叉.jpg"];    result = [zip addFileToZip:image2 newname:@"杀生丸.jpg"];    if( ![zip CloseZipFile2] ){              zipFile = @"";    }    [zip release]; 解压缩    ZipArchive* zip = [[ZipArchive alloc] init];    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);    NSString *documentPath = ([paths count] > 0) ?
