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zlib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];
