Dear Everyone

If you wish to add a function to merely list the items in the zip file, and return this as an NSString array, insert the following lines into ZipArchive?.mm:

- (NSMutableArray *) getZipFileContents
{
        BOOL success = YES;
        int ret = unzGoToFirstFile( _unzFile );
        NSMutableArray * AllFilenames = [[NSMutableArray alloc] initWithCapacity:40];
        
        if( ret!=UNZ_OK )
        {
                [self OutputErrorMessage:@"Failed"];
        }
        
        do{
                if( [_password length]==0 )
                        ret = unzOpenCurrentFile( _unzFile );
                else
                        ret = unzOpenCurrentFilePassword( _unzFile, [_password cStringUsingEncoding:NSASCIIStringEncoding] );
                if( ret!=UNZ_OK )
                {
                        [self OutputErrorMessage:@"Error occured"];
                        success = NO;
                        break;
                }
                
                // reading data and write to file
                unz_file_info   fileInfo ={0};
                ret = unzGetCurrentFileInfo(_unzFile, &fileInfo, NULL, 0, NULL, 0, NULL, 0);
                if( ret!=UNZ_OK )
                {
                        [self OutputErrorMessage:@"Error occurs while getting file info"];
                        success = NO;
                        unzCloseCurrentFile( _unzFile );
                        break;
                }
                char* filename = (char*) malloc( fileInfo.size_filename +1 );
                unzGetCurrentFileInfo(_unzFile, &fileInfo, filename, fileInfo.size_filename + 1, NULL, 0, NULL, 0);
                filename[fileInfo.size_filename] = '\0';
                
                // check if it contains directory
                NSString * strPath = [NSString stringWithCString:filename];
                BOOL isDirectory = NO;
                if( filename[fileInfo.size_filename-1]=='/' || filename[fileInfo.size_filename-1]=='\\')
                        isDirectory = YES;
                free( filename );
                if( [strPath rangeOfCharacterFromSet:[NSCharacterSet characterSetWithCharactersInString:@"/\\"]].location!=NSNotFound )
                {// contains a path
                        strPath = [strPath stringByReplacingOccurrencesOfString:@"\\" withString:@"/"];
                }
                
                // Copy name to array
                [AllFilenames addObject:[strPath copy]];
                                
                unzCloseCurrentFile( _unzFile );
                ret = unzGoToNextFile( _unzFile );
        }  while( ret==UNZ_OK && UNZ_OK!=UNZ_END_OF_LIST_OF_FILE );

        return [AllFilenames autorelease];
}

Thank you..
But, I want to see rar compress..
I found PhysicsFS.
PhysicsFS on the Iphone | Gamingseasons
It is a file manager which enables easy access of the contents of quake files(PAK), doom files (WAD), zip files and more.
