Compression and decompression files for iOS development

Ziparchive is based on the open source code "Minizip" zip compression and decompression of the Objective-c class, very simple to use
Method: Download Ziparchive.zip from http://code.google.com/p/ziparchive/, add code to project after decompression, and adding zlib library to Project
How to use:
1. Compression: Ziparchive can compress multiple files, only need to addfiletozip the file one by one.

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. Unzip:

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];
